Mandragora turcomanica

Mandragora turcomanica, the Turkmenian mandrake, [3] is a perennial herbaceous plant in the family Solanaceae, native to the Kopet Dag mountains in Turkmenistan and one location in neighbouring Iran. It differs from the mandrakes found around the Mediterranean ( Mandragora autumnalis and/or Mandragora officinarum ) chiefly by being larger.

Description

Mandragora turcomanica is a perennial herbaceous plant with a thick, often branched tap-root. It has little or no stem, the leaves being arranged in a basal rosette. The lowest leaves are up to 90 cm (3 ft) long by 60 cm (2 ft) across (less in Iranian specimens), the upper leaves being smaller. The lower leaves are usually irregularly toothed towards the end, the upper leaves being entire. Both sides of the leaves have scattered hairs, mainly along the veins. [3] [4]

Flowering time is autumn to early spring (October to March) in Turkmenistan, late winter to early spring (February to March) in Iran. The flowers are borne in the centre of the rosette, on stalks (pedicels) up to 3 cm (1.2 in) long, usually singly but sometimes with up to 6 flowers. The five sepals are fused at the base to form a bell-shaped cup, lobed to about two thirds of its length of 15–20 mm (0.6–0.8 in) when in flower, lengthening in fruit. The five violet or purple petals are 20–25 mm (0.8–1.0 in) long and similarly fused and lobed. The stamens are included within the flower, joined to the fused petals at the base. The anthers are pale blue. The ripe fruit (a berry) is yellow to orange, 40–60 mm (1.6–2.4 in) in diameter, described as smelling of melons, and containing yellow to light brown seeds, 4–5 mm (0.16–0.20 in) by 6–7 mm (0.24–0.28 in). [3] [4]

Taxonomy

Mandragora turcomanica was first described in 1942 by Olga F. Mizgireva [2] (Ольга Фоминична Мизгирёва), a Turkmenian botanist and former artist. [5] Mizgireva differentiated M. turcomanica from the Mediterranean mandrakes chiefly by the size of the plant (M. turcomanica is larger), the colour of the anthers and the relative sizes of the calyx and corolla. [3]

Ungricht et al. in their 1998 revision of the genus Mandragora retained M. turcomanica as a separate species, although they were not able to examine either any herbarium specimens or any live plants. They said that further study was needed to compare the ranges of variation of this species and their concept of Mandragora officinarum . [3] In 2003, Akhani and Ghorbani reported the occurrence of M. turcomanica in Iran. They considered that it was sufficiently similar to the Mediterranean species that the rank of subspecies rather than species might be appropriate, although further study was needed. [4] A 2010 molecular phylogenetic study placed M. turcomanica in a clade with the authors' concept of Mandragora autumnalis . [6]

Distribution and habitat

Mandragora turcomanica was first discovered in the south-western Kopet Dag mountains in Turkmenistan. Ungricht et al. queried whether it might also occur in the same mountain chain across the border in Iran. [3] It was reported in Iran in 2003, near the village of Dahaneh close to the Golestan National Park. It was growing in gardens, where it had been transplanted from wild sources. [4] In Turkmenistan, the species grows in shrubland, in ravines and on stony mountain slopes, especially among Paliurus spina-christi , at altitudes of 500–700 m (1,600–2,300 ft). [3]

Conservation

Mandragora turcomanica was reported to be "on the verge of extinction" in Turkmenistan in 2001. [7] There were said to be fewer than 500 plants in their natural habitats in Turkmenistan in 1999. Only about 50 plants were in cultivation in the sole Iranian location in 2010. [4]

Toxicity and uses

All the species of Mandragora are described as toxic and to have had traditional medicinal uses. [3] Mizgireva is reported to have said in 1942 that it was used by the local people in Turkmenistan as a medicinal plant. [8] In Iran, the discoverers of M. turcomanica described it as an "old medicinal and mythically important plant" but said that they were unable to discover earlier local uses. [4]

At the beginning of the growth cycle, the leaves of M. turcomanica contained 0.3% of alkaloids; later the roots contained 0.2%. By contrast the unripe fruits contained only 0.07% and the ripe seeds only 0.03%. The main alkaloids were the tropane alkaloids scopolamine (hyoscine), apohyoscine and hyoscyamine; others detected included belladonnine, norhyoscyamine, apoatropine, 3α-trigloyloxytropan-6β-ol and tigloidine. [9] Tropane alkaloids are potentially highly toxic. [10] A wide range of lipids and lipid-like compounds were also identified. [11]

<i>Atropa</i> Genus of plants

Atropa is a genus of flowering plants in the nightshade family, Solanaceae : tall, calcicole, herbaceous perennials, bearing large leaves and glossy berries particularly dangerous to children, due to their combination of an attractive, cherry-like appearance with a high toxicity. Atropa species favour temperate climates and alkaline soils, often growing in light shade in woodland environments associated with limestone hills and mountains. Their seeds can remain viable in the soil for long periods, germinating when the soil of sites in which plants once grew is disturbed by human activity or by natural causes, e.g. the windthrow of trees. The best-known member of the genus Atropa is Deadly Nightshade - the poisonous plant par excellence in the minds of many. The pharmacologically active ingredients of Atropa species include atropine, scopolamine, and hyoscyamine, all tropane alkaloids having anticholinergic, deliriant, antispasmodic and mydriatic properties. The genus is named for Άτροπος (Atropos) - lit. 'she who may not be turned (aside)' - one of the Three Fates and cutter of the thread of life / bringer of death - in reference to the extreme toxicity of A.belladonna and its fellow species - of which three others are currently accepted.

<i>Atropa belladonna</i> Species of toxic flowering plant in the nightshade family.

Atropa belladonna, commonly known as belladonna or deadly nightshade, is a poisonous perennial herbaceous plant in the nightshade family Solanaceae, which also includes tomatoes, potatoes, and eggplant (aubergine). It is native to Europe, North Africa, and Western Asia. Its distribution extends from Great Britain in the west to western Ukraine and the Iranian province of Gilan in the east. It is also naturalised or introduced in some parts of Canada and the United States.

Hyoscyamine Pharmaceutical drug

Hyoscyamine is a naturally occurring tropane alkaloid and plant toxin. It is a secondary metabolite found in certain plants of the family Solanaceae, including henbane, mandrake, angel's trumpets, jimsonweed, tomato, the sorcerers' tree, and deadly nightshade. It is the levorotary isomer of atropine and thus sometimes known as levo-atropine.

<i>Brugmansia</i> Genus of flowering plants in the nightshade family Solanaceae

Brugmansia is a genus of seven species of flowering plants in the family Solanaceae. They are woody trees or shrubs, with pendulous flowers, and have no spines on their fruit. Their large, fragrant flowers give them their common name of angel's trumpets, a name sometimes used for the closely related genus Datura..

Deliriant

Deliriants are a class of hallucinogen. The term was introduced by David F. Duncan and Robert S. Gold to distinguish these drugs from psychedelics and dissociatives, such as LSD and ketamine respectively, due to their primary effect of causing delirium, as opposed to the more lucid states produced by such other hallucinogens as those represented by psychedelics and dissociatives. The term is generally used to refer to anticholinergic drugs which are substances that inhibit the function of the neurotransmitter acetylcholine. Common examples of deliriants include plants of the genus Datura as well as higher than recommended dosages of Diphenhydramine (Benadryl).

<i>Nicandra physalodes</i> Species of flowering plant in the tomato family Solanaceae

Nicandra physalodes is a species of flowering plant in subfamily Solanoideae of the nightshade family. It is known by the common names apple-of-Peru and shoo-fly plant. It is thought originally to have been native to western South America, including Peru, and is known elsewhere as an introduced and ruderal species – sometimes as a weed – in tropical, subtropical and, to a lesser extent, temperate areas all over the world. It has also long been cultivated as an ornamental plant for its attractive flowers and curious fruits and has been adopted into the traditional medicine of countries far-removed from its original home.

<i>Mandragora officinarum</i> Species of plant

Mandragora officinarum is the type species of the plant genus Mandragora. It is often known as mandrake, although this name is also used for other plants. As of 2015, sources differed significantly in the species they use for Mandragora plants native to the Mediterranean region. The main species found around the Mediterranean is called Mandragora autumnalis, the autumn mandrake. In a broader circumscription, all the plants native to the regions around the Mediterranean Sea are placed in M. officinarum, which thus includes M. autumnalis. The names autumn mandrake and Mediterranean mandrake are then used. Whatever the circumscription, Mandragora officinarum is a perennial herbaceous plant with ovate leaves arranged in a rosette, a thick upright root, often branched, and bell-shaped flowers followed by yellow or orange berries.

Anisodus tanguticus is a species of flowering plant in the family Solanaceae which includes many important agricultural plants. It is mostly found growing in the Qinghai-Tibetan Plateau. A. tanguticus is collected and used mostly for its medicinal effects thought to be derived from the plant's biologically active nicotine and tropane alkaloids. It has a significant impact in China as one of the 50 fundamental herbs used in traditional Chinese medicine.

Tropane alkaloid Class of chemical compounds

Tropane alkaloids are a class of bicyclic [3.2.1] alkaloids and secondary metabolites that contain a tropane ring in their chemical structure. Tropane alkaloids occur naturally in many members of the plant family Solanaceae. Some tropane alkaloids have pharmacological properties and can act as anticholinergics or stimulants.

<i>Mandragora</i> (genus) Genus of plants

Mandragora is a plant genus belonging to the nightshade family (Solanaceae). Members of the genus are known as mandrakes. There are between three and five species in the genus. The one or two species found around the Mediterranean constitute the mandrake of ancient writers such as Dioscorides. Two or three further species are found eastwards into China. All are perennial herbaceous plants, with large tap-roots and leaves in the form of a rosette. Individual flowers are bell-shaped, whitish through to violet, and are followed by yellow or orange berries.

Mandrake Plant root

A mandrake is the root of a plant, historically derived either from plants of the genus Mandragora found in the Mediterranean region, or from other species, such as Bryonia alba, the English mandrake, which have similar properties. The plants from which the root is obtained are also called "mandrakes". Mediterranean mandrakes are perennial herbaceous plants with ovate leaves arranged in a rosette, a thick upright root, often branched, and bell-shaped flowers followed by yellow or orange berries. They have been placed in different species by different authors. They are highly variable perennial herbaceous plants with long thick roots and almost no stem. The leaves are borne in a basal rosette, and are variable in size and shape, with a maximum length of 45 cm (18 in). They are usually either elliptical in shape or wider towards the end (obovate), with varying degrees of hairiness.

<i>Mandragora autumnalis</i> Species of plant

Mandragora autumnalis, known as mandrake or autumn mandrake, is recognized by some sources as a separate species from Mandragora officinarum, although with different circumscriptions. Others regard it as merely part of this very variable species. Plants given the name Mandragora autumnalis consist of a rosette of leaves up to 60 cm (2 ft) across, close to the ground, with a central group of usually purplish flowers followed by yellow or orange berries. The large tap-roots as well as the leaves contain alkaloids and are toxic. They have traditional uses as herbal medicines.

Mandragora caulescens, the Himalayan mandrake, is a perennial herbaceous plant in the family Solanaceae, native to the Himalayas and mountainous regions of Myanmar and south-west China. One of the differences from the other species of Mandragora is that it has a stem, whereas they are stemless. Like all species of Mandragora, it contains tropane alkaloids, making it toxic. It is used in traditional Chinese medicine.

Solanaceae Family of flowering plants that includes tomatoes, potatoes and tobacco

The Solanaceae, or nightshades, are a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.

Atropa pallidiflora is a close relative of the infamous deadly nightshade and, like it, is an extremely poisonous plant, containing a variety of tropane alkaloids valued in medicine for their anticholinergic, antispasmodic and mydriatic properties and deliriant in excess. Atropa pallidiflora is the least well-known of the four currently accepted species of Atropa and is endemic to the remarkable Caspian Hyrcanian mixed forests of Northern Iran, which can boast all the species of Atropa currently recognised, with the sole exception of the strictly Ibero-Maghrebi A.baetica. The binomial Atropa pallidiflora was published by Eva Schönbeck-Temesy in volume 100 ('Solanaceae') of Karl Heinz Rechinger's monumental Flora Iranica in 1972. The specific name pallidiflora signifies 'bearing flowers of a pale, wan or washed-out hue' and, while appropriate, is not especially evocative, given that the flowers of most Atropa species are far from vivid. The flowers of A. pallidiflora, like those of A.baetica, vary from greenish to yellow, but, as the designation 'having pallid flowers' might suggest, the yellow in question is a dingy greenish-yellow that is far from ornamental. The geographical term 'Hyrcanian' in the common name signifies that the plant is native to what was once the satrapy of Hyrcania, the name of which derives from an Iranian root meaning 'wolf' : Hyrcania is thus the 'Land of Wolves'. The name is an apt one, since the Hyrcanian forests have long been known as a hunting ground of legendary richness and beauty : the lush forests could support an abundance of large, mammalian herbivores, which in turn could support an abundance of apex predators - notably the wolf, but also the Persian leopard and even the tiger. The word 'Hyrcanian' will be familiar to any diligent reader of the works of William Shakespeare, as an epithet of the proverbially savage Caspian Tiger, known to the dramatist from his reading of the works of various Latin authors - who, in turn, were familiar with the Ancient Greek coinage 'Hyrcania' and the lands adjoining the Caspian Sea to which the place name referred. Regarding the richness of the Hyrcanian flora - of which Atropa pallidiflora is a noteworthy element - it is worth mentioning that the name of the modern Iranian province of Golestan has the delightful meanings of 'Rose Garden' and 'Land of Flowers'.
