Flemingia Grahamiana
''Flemingia grahamiana'' is a species of flowering plant in the family Fabaceae. Extracts of the plant are used in the dyeing of silk and cotton in parts of India, Africa, and the Middle East. Description An erect herb or subshrub, ''Flemingia grahamiana'' can grow up to 1.8 m tall but commonly shorter, it is much branched, deeply rooted and sometimes tuberous. Leaves appear digitately trifoliate with stipules and petioles present; leaflets are elliptic to lanceolate in outline, up to 13 cm long and 7 cm wide. Inflorescence is an axillary raceme, corolla is yellowish white to pink in color, calyx is tubular and up to 1.5 cm long.

Chalcone
Chalcone is the organic compound C6H5C(O)CH=CHC6H5. It is an α,β-unsaturated ketone. A variety of important biological compounds are known collectively as chalcones or chalconoids. They are widely known bioactive substances, fluorescent materials, and chemical intermediates. Chemical properties Chalcones have two absorption maxima at 280 nm and 340 nm. Biosynthesis Chalcones and chalconoids are synthesized in plants as secondary metabolites. The enzyme chalcone synthase, a type III polyketide synthase, is responsible for the biosynthesis of these compounds. The enzyme is found in all "higher" (vascular) and several "lower" ( non-vascular) plants. Laboratory synthesis Chalcone is usually prepared by an aldol condensation between benzaldehyde and acetophenone. : This reaction, which can be carried out without any solvent, is so reliable that it is often given as an example of green chemistry in undergraduate education. Potential pharmacology Chalcones and thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isoflavone
Isoflavones are a type of naturally-occurring isoflavonoids, many of which act as phytoestrogens in mammals. Isoflavones occur in many plant species, but are especially high in soybeans. Although isoflavones and closely-related phytoestrogens are sold as dietary supplements, there is little scientific evidence for either the safety of long-term supplementation or of health benefits from these compounds. Some studies indicate that isoflavone supplementation may help lower the risk of hormone-related cancers. Organic chemistry and biosynthesis Isoflavone is an isomer of flavone, which is chromone substituted with a phenyl group in the 2-position. In isoflavone, the phenyl group is in the 3-position. Substituted isoflavone derivatives are related to the parent by the replacement of two or three hydrogen atoms with hydroxyl groups. Isoflavone differs from flavone (2-phenyl-4''H''-1-benzopyr-4-one) in location of the phenyl group. Isoflavones are produced via a branch of the ...

Prenylflavonoid
Prenylated flavonoids or prenylflavonoids are a sub-class of flavonoids. They are widely distributed throughout the plant kingdom. Some are known to have phytoestrogenic or antioxidant properties. They are given in the list of adaptogens in herbalism. Chemically they have a prenyl group attached to their flavonoid backbone. It is usually assumed that the addition of hydrophobic prenyl groups facilitate attachment to cell membranes. Prenylation may increase the potential activity of its original flavonoid. Monoprenyl isoflavone epoxidase is a key enzyme in fungal ''Botrytis cinerea'' metabolism of prenylated flavonoids. Many prenylflavonoids appear to have anticancer activity in vitro. Prenylchalcones, prenylflavones, prenylflavonols and prenylflavanones are classes of prenylflavonoids. Examples 6-Prenylnaringenin, 6-geranylnaringenin, 8-prenylnaringenin and isoxanthohumol can be found in hops and beer. Of the prenylflavonoids, 8-prenylnaringenin is the most potent phytoe ...

Ethnomedical
Ethnomedicine is a study or comparison of the traditional medicine based on bioactive compounds in plants and animals and practiced by various ethnic groups, especially those with little access to western medicines, e.g., indigenous peoples. The word ''ethnomedicine'' is sometimes used as a synonym for ''traditional medicine''.Acharya, Deepak and Shrivastava Anshu: ''Indigenous Herbal Medicines: Tribal Formulations and Traditional Herbal Practices''. Aavishkar Publishers Distributor, Jaipur / India 2008, , p. 440. Ethnomedical research is interdisciplinary; in its study of traditional medicines, it applies the methods of ethnobotany and medical anthropology. Often, the medicine traditions it studies are preserved only by oral tradition. In addition to plants, some of these traditions constitute significant interactions with insects on the Indian Subcontinent, in Africa, or elsewhere around the globe. Scientific ethnomedical studies constitute either anthropological research o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decoction
Decoction is a method of extraction by boiling herbal or plant material (which may include stems, roots, bark and rhizomes) to dissolve the chemicals of the material. It is the most common preparation method in various herbal medicine systems. Decoction involves first drying the plant material; then mashing, slicing, or cutting the material to allow for maximum dissolution; and finally boiling in water to extract oils, volatile organic compounds and other various chemical substances. Occasionally, aqueous ethanol or glycerol may be used instead of water. Decoction can be used to make tisanes, tinctures and similar solutions. Decoctions and infusions may produce liquids with differing chemical properties, as the temperature or preparation difference may result in more oil-soluble chemicals in decoctions versus infusions. The process can also be applied to meats and vegetables to prepare bouillon or stock, though the term is typically only used to describe boiled plant extracts, usu ...

Flora Of East Tropical Africa
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Flora Of India
The flora of India is one of the richest in the world due to the wide range of climate, topology and habitat in the country. There are estimated to be over 18,000 species of flowering plants in India, which constitute some 6-7 percent of the total plant species in the world. India is home to more than 50,000 species of plants, including a variety of endemics. The use of plants as a source of medicines has been an integral part of life in India from the earliest times. There are more than 3000 Indian plant species officially documented as possessing into eight main floristic regions : Western Himalayas, Eastern Himalayas, Assam, Indus plain, Ganges plain, the Deccan, Malabar and the Andaman Islands. Forests and wildlife resources In 1992, 743,534 km2 of land in the country was forested of which 92 percent was government land. This amounts to 22.7 percent land coverage, compared to the recommended 33 percent of the National Forest Policy Resolution 1952. The majority ...
