    ABSTRACT: Root of Cocos nucifera Linn. (Arecaceae) is astringent, diuretic, anthelmintic and useful in curing pharyngodynia, uterine disorders, blenorrhagia, bronchitis, hepatopathy, strangury and helminthiasis. It is an important commodity in folklore medicines of south India for urinary troubles. So far there is no record on detailed pharmacognostic evaluation of this crude drug, hence this communication throws light on parameters essential to fix standards for this medicinal material.

    ABSTRACT: Root bark of Alangium salvifolium (Linn.f.) Wang. (Family Alangiaceae) is a reputed drug mentioned in the ancient books of Ayurveda and Siddha for the treatment of epilepsy, jaundice, hepatitis etc. Root bark of the plant was subjected to macro-microscopic, photomicrographic, physico-chemical, fluorescence, preliminary phytochemical, TLC and HPTLC to fix quality standards for this drug. Microscopic studies have shown stratified phellem, rhytidome, cluster crystals of calcium oxalate and uni- to triseriate medullary rays in the root bark. Chloroform, ethyl acetate, ethanol extracts and alkaloid fraction revealed characteristic chromatographic patterns with presence of alkaloids in varying concentrations. This study would be useful in the identification and authentication of the raw drug.

    ABSTRACT: Physicochemical parameters of roots of three Plumbago species, Plumbago capensis, P. rosea and P. zeylanica belonging to Plumbaginaceae were analyzed. Microbial contamination, aflatoxins, pesticide residue and heavy metal content were also determined. Attempt has also been made to estimate the biologically active chemical plumbagin present in them and the data compared. The study ensures that the quality control parameters do help in the proper standardization of the crude drugs in drug development process for global acceptance.

    ABSTRACT: Two flavonoids and two carboxylic acids have been isolated from the ethyl acetate extract of the roots. The structures of these compounds have been established as myricetin-3,3',5',7-tetra methyl ether 1. ampelopsin-3',4',5',7-tetramethyl ether 2, plumbagic acid 3 and roseanoic acid 4 on the basis of UV, IR, H-1 and C-13 NMR and mass spectrum studies. The two carboxylic acids 3 and 4 arc reported here for the first time. Compounds 1 and 2 are the first report from the genus plumbago.
