PRELIMINARY PHYTOCHEMICAL INVESTIGATION AND TLC ANALYSIS OF PEEL AND SEED EXTRACTS OF PERSEA AMERICANA
Journal Title: Asian J of Pharm Sci & Tech - Year 2015, Vol 5, Issue 3
Abstract
ABSTRACT Medicinal plants are as “old as mankind on earth” which are used in herbal medicine to treat diseases. Excellent research works and reviews have documented a list of medicinal plants used in every part of the world for the treatment of a variety of disorders like asthma, diabetes, malaria, elephantiasis, Cold, etc. for as long as history can remember. It is reported that many of these medicinal plants possess bioactive compounds that exhibit physiological activity against different illness. Noted that these plant bioactive compounds are in chemical forms, and are called phytochemicals. Studies have shown that some of these phytochemicals aside their medicinal values, can as well act as body nutrients. Persea americana (Lauraceae), the plant that produces alligator pear as fruit, is among such plants whose constituents act as medicine and body nutrients. It is a tall evergreen tree that can grow up to 65 feet in height. They have a green-skinned, fleshy body that may be pear-shaped, egg-shaped, or spherical; the fruit is edible when ripped. In herbal medicine, infusion, concoction and extracts made from any part of the plant are effective against hypertension, cancer, menstrual problems, inflammation, wounds, etc. The elliptic dark green peel of P. americana, & the seeds which are normally discarded after consumption of the fruit has received very little scientific scrutiny. Present study reports the phytochemical properties which have been carried out on the seed and peel extract using hexane, ethyl acetate, water, methanol, acetone, chloroform & ethanol. The preliminary phytochemical screening of this plant crude extracts showed the maximum phytochemical constituents with methanolic extracts and hence for further studies the methanolic extracts were considered. The Phytochemical analysis shows the presence of Phenols, Flavanoids, Terpenoids steroids in methanolic peel and seed extracts. Thin layer chromatography (TLC) has been carried out on the methanolic peel and seed extracts of Persea americana, which further illustrates the presence of tetraterpenoid namely beta carotene. Key words: Persea americana, Lauraceae, Phytochemicals, TLC, Tetraterpenoid, Extract.
