Lippia is a genus of flowering plants belonging to the Verbenaceae family. It contains about 220 species with diverse ethnopharmacological applications. Myriad of biologically active phytoconstituents abound in Lippia. The essential oil chemotypes found in Lippia species included myrcenone rich-type, carvone rich-type, piperitenone rich-type, ipsenone rich-type, linalool rich-type, citral rich-type, carvacrol rich-type, thymol rich-type and lippiol rich-type. Other constituents apart from essential oils isolated and chemically characterized were highlighted. β-caryophyllene and iridoid glycosides were notable as chemotaxonomic marker compounds which were common to many of Lippia...

The hypolipidemic activity of Aloe vera (Family: Liliaceae) extract has been studied in two models of hyperlipidemia in rats. In an acute model, hyperlipidemia was induced by injecting a single dose of triton WR-1339 (400mg/kg, b.w.) intraperitoneally in rats. Feeding with Aloe vera extract at the dose of 500 mg/ kg, b.w. exerted a significant lipid-lowering effect as assessed by the reversal of plasma levels of total cholesterol (TC), phospholipids (PL), triglyceride (TG) and reactivation of post-heparin lipolytic activity (PHLA). In the chronic model, hyperlipidemia was induced by feeding with cholesterol-rich- HFD in rats. The treatment with seeds extracts of Aloe vera (500 mg/ kg b.w) simultaneously for 15 days also caused lowering of lipid levels in plasma and liver following reactivation of plasma post-heparin lipolytic activity and hepatic lipoprotein lipase activity in animals. The hypolipidemic activity of Aloe vera was compared with a standard drug guggulipid (200 mg/ kg, b.w.) in both...

The present investigation has been carried out to determine the antioxidant activity of the ethanolic extracts obtained from plant seeds belonging to family Leguminosae i.e., Lens culinaris, Vigna unguiculata, Dolichos biflorus and Phalaseous. Phenolic compounds present in the extracts showed the antioxidant and antiradical properties when investigated using a ferrous ion chelating ability and reducing power assay. The results indicated that ethanolic extracts of all four plant seeds resembled in the activities above. Phenolic constituents contained in plant mentioned above seeds may have a future role as ingredients in the development of functional...
