Cymbopogon martinii is a species of grass in the genus Cymbopogon (lemongrasses) native to India and Indochina but widely cultivated in many places for its aromatic oil. [3] [4] It is best known by the common name palmarosa (palm rose) as it smells sweet and rose-like. Other common names include Indian geranium, gingergrass, rosha, and rosha grass.
The essential oil of this plant, which contains the chemical compound geraniol, is valued for its scent and for traditional medicinal and household uses. Palmarosa oil may be an effective insect repellent when applied to stored grain and beans, [5] an antihelmintic against nematodes, [6] and an antifungal and mosquito repellent. [7] Palmarosa oil, which has a scent similar to that of roses, is added to soaps and cosmetics. [7]
It is widely used for rose-smelling perfumes and cosmetics. [8] It has been used for aromatherapy. [4] Palmarosa oil is an antifungal that fights against Aspergillus niger (commonly known as black mold), Chaetomium globosum (also known as soil mold), and Penicillium funiculosum , which is a plant pathogen. [3]
C. martinii grows fairly tall, ranging from 1.3 to 3 m (4 ft 3 in to 9 ft 10 in) in height with a pale green color and a strong thin stem. This crop grows slowly, taking three months to flower; once it has flowered, it can be harvested. It received the name palmarosa from the sweet-smelling floral rose aroma it gives off. [9]
Palmarosa grows in the wild in certain wetlands of India and Nepal. [10] Palmarosa oil is extracted from the stem of the grass by distillation of dried leaves. [11] Once the stems and leaves have been distilled for two to three hours, to separate the oil from the palmarosa plant matter, then the leftover grass residue is turned into manure or composted. [12]
The most efficient way to grow palmarosa is in a nursery with much irrigation and soil pH of 7-8. [13] Two or three days before planting, it is best to overwhelm the soil with water to increase soil moisture above 60% when planting the seeds. This moisture increases the germination of the seed and increases weed control in the nursery beds as well. It is also recommended to flood the soil monthly to maintain a high moisture level in the soil. Irrigation in a nursery is most important for the first 40 days. Palmarosa grass grows well in sandy texture soil with low nitrogen, sufficient phosphorus and potassium, but requires frequent manual weeding. [14] Palmarosa is often intercropped to help suppress weeds, thus increasing yields and land use efficiency. Farmers often intercrop with pigeon peas; millet and sorghum also work well with row or strip intercropping because palmarosa can be harvested three to four times per year. [15] [12]
A nursery is needed or there will be poor growth yields, that may not bring any profit to the farmer and potentially the farmer could have an economical loss. This requirement increases the startup cost for farmers which some farmers are unable to pay. [15] If not grown in a nursery this will increase the weeding labour inputs by over 70% and decrease the yield. Farmers will be spending more time weeding the plots and will receive a smaller return than if they had a nursery. [16]
Spearmint, also known as garden mint, common mint, lamb mint and mackerel mint, is native to Europe and southern temperate Asia, extending from Ireland in the west to southern China in the east. It is naturalized in many other temperate parts of the world, including northern and southern Africa, North America, and South America. It is used as a flavouring in food and herbal teas. The aromatic oil, called oil of spearmint, is also used as a flavoring and sometimes as a scent.
Companion planting in gardening and agriculture is the planting of different crops in proximity for any of a number of different reasons, including weed suppression, pest control, pollination, providing habitat for beneficial insects, maximizing use of space, and to otherwise increase crop productivity. Companion planting is a form of polyculture.
Cymbopogon, also known as lemongrass, barbed wire grass, silky heads, oily heads, Cochin grass, Malabar grass, citronella grass or fever grass, is a genus of Asian, African, Australian, and tropical island plants in the grass family. Some species are commonly cultivated as culinary and medicinal herbs because of their scent, resembling that of lemons . The name Cymbopogon derives from the Greek words kymbe and pogon "which mean [that] in most species, the hairy spikelets project from boat-shaped spathes." Lemongrass and its oil are believed to possess therapeutic properties.
Citronella oil is an essential oil obtained from the leaves and stems of different species of Cymbopogon (lemongrass). The oil is used extensively as a source of perfumery chemicals such as citronellal, citronellol, and geraniol. These chemicals find extensive use in soap, candles and incense, perfumery, cosmetic, and flavouring industries throughout the world.
Geraniol is a monoterpenoid and an alcohol. It is the primary component of citronella oil and is a primary component of rose oil and palmarosa oil. It is a colorless oil, although commercial samples can appear yellow. It has low solubility in water, but it is soluble in common organic solvents. The functional group derived from geraniol is called geranyl.
Chrysopogon zizanioides, commonly known as vetiver and khus, is a perennial bunchgrass of the family Poaceae.
Linalool refers to two enantiomers of a naturally occurring terpene alcohol found in many flowers and spice plants. Linalool has multiple commercial applications, the majority of which are based on its pleasant scent. A colorless oil, linalool is classified as an acyclic monoterpenoid. In plants, it is a metabolite, a volatile oil component, an antimicrobial agent, and an aroma compound. Linalool has uses in manufacturing of soaps, fragrances, food additives as flavors, household products, and insecticides. Esters of linalool are referred to as linalyl, e.g. linalyl pyrophosphate, an isomer of geranyl pyrophosphate.
Citronellal or rhodinal (C10H18O) is a monoterpenoid aldehyde, the main component in the mixture of terpenoid chemical compounds that give citronella oil its distinctive lemon scent.
Citral is an acyclic monoterpene aldehyde. Being a monoterpene, it is made of two isoprene units. Citral is a collective term which covers two geometric isomers that have their own separate names; the E-isomer is named geranial or citral A. The Z-isomer is named neral or citral B. These stereoisomers occur as a mixture, often not in equal proportions; e.g. in essential oil of Australian ginger, the neral to geranial ratio is 0.61.
The holy anointing oil formed an integral part of the ordination of the priesthood and the High Priest as well as in the consecration of the articles of the Tabernacle and subsequent temples in Jerusalem. The primary purpose of anointing with the holy anointing oil was to sanctify, to set the anointed person or object apart as qodesh, or "holy".
Rose oil is the essential oil extracted from the petals of various types of rose. Rose ottos are extracted through steam distillation, while rose absolutes are obtained through solvent extraction, the absolute being used more commonly in perfumery. The production technique originated in Greater Iran. Even with their high price and the advent of organic synthesis, rose oils are still perhaps the most widely used essential oil in perfumery.
Cenchrus purpureus, synonym Pennisetum purpureum, also known as Napier grass, elephant grass or Uganda grass, is a species of perennial tropical grass native to African grasslands. It has low water and nutrient requirements, and therefore can make use of otherwise uncultivated lands.
Caryophyllene, more formally (−)-β-caryophyllene (BCP), is a natural bicyclic sesquiterpene that is a constituent of many essential oils, especially clove oil, the oil from the stems and flowers of Syzygium aromaticum (cloves), the essential oil of Cannabis sativa, copaiba, rosemary, and hops. It is usually found as a mixture with isocaryophyllene and α-humulene, a ring-opened isomer. Caryophyllene is notable for having a cyclobutane ring, as well as a trans-double bond in a 9-membered ring, both rarities in nature.
Pelargonium graveolens is a Pelargonium species native to the Cape Provinces and the Northern Provinces of South Africa, Zimbabwe and Mozambique. Common names include rose geranium, sweet scented geranium, old-fashioned rose geranium, and rose-scent geranium.
Cymbopogon flexuosus, also called Cochin grass, East-Indian lemon grass or Malabar grass, is a perennial grass native to India, Sri Lanka, Burma, and Thailand. It is placed in the genus Cymbopogon (lemongrasses).
Cymbopogon citratus, commonly known as West Indian lemon grass or simply lemon grass, is a tropical plant native to South Asia and Maritime Southeast Asia and introduced to many tropical regions.
