Maesa lanceolata

Maesa lanceolata, the false assegai, is a tree species that is widespread in the Afrotropics, including Madagascar. [1] It occurs from the southern Arabian Peninsula, southwards to the Eastern Cape, South Africa. It grows on stream verges, river banks and forest verges, where it is often a pioneer plant.

Description

Maesa lanceolata grows either as a shrub or tree, when growing as a tree, it is capable of reaching 10 m tall, but it has been observed to reach 20 m. [2] It has a grey, brown to reddish brown bark that is vertically fissured, the slash is pink turning brown with a dark reddish exudate. [3] Leaves are petiolate, with the petiole capable of reaching 4 cm long. [3] Leaflets are elliptical to lanceolate in outline, they can reach 16 cm in length and 7 cm in width with a margin that tends to be either serrate to crenate; the apex is acute and base is rounded to obsute. [3] Flowers are arranged in shortly pedunculate axillary panicles, they are numerous and white to yellowish in color. [3] [2]

The fruits are yellow in color and globose in shape, they contain up to 20 seeds.

Ecology

The yellow fruits of the species are consumed by the Yellow-whiskered greenbul and the lolive-breasted mountain greenbul but can be toxic to humans. [4] [2]

Distribution

Occurs in Tropical Africa and the Arabian peninsula. They are commonly found in montane forest and gallery forest environments. [2]

Chemistry

Oleane type pentacyclic triterpenoid saponins have been isolated from the leaves of the species, [5] also isolated from the leaves and fruits of the species is the bioctive benzoquinone, Maesanin. [6]

Uses

Though considered toxic to human the extracts of Maesa lanceolata have been used in different communities to treat various ailments. In East Africa root and fruit extracts are used by native healers in decoctions to treat cholera disease, tapeworm and sore throat. [7]

<i>Aesculus pavia</i> Species of tree

Aesculus pavia, known as red buckeye or firecracker plant, is a species of deciduous flowering plant. The small tree or shrub is native to the southern and eastern parts of the United States, found from Illinois to Virginia in the north and from Texas to Florida in the south. It is hardy far to the north of its native range, with successful cultivation poleward to Arboretum Mustila in Finland.

Saponins are bitter-tasting, usually toxic plant-derived secondary metabolites. They are organic chemicals and have a foamy quality when agitated in water and a high molecular weight. They are present in a wide range of plant species throughout the bark, leaves, stems, roots and flowers but particularly in soapwort, a flowering plant, the soapbark tree, common corn-cockle, baby's breath and soybeans. They are used in soaps, medicines, fire extinguishers, dietary supplements, steroid synthesis, and in carbonated beverages. Saponins are both water and fat soluble, which gives them their useful soap properties. Some examples of these chemicals are glycyrrhizin and quillaia, a bark extract used in beverages.
