Background: Hibiscus rosa-sinensis Linn. (Fam.Malvaceae) is a small evergreen shrub cultivated in gardens throughout India. The decoction of flowers is used in Indian system of Medicine for bronchial inflammation, urinary astringent and cardio tonic, to promote growth and to prevent graying of hair. The dried flowers of Rhododendron arboreum Sm. (Fam.Ericaceae) are morphologically looking similar to Hibiscus rosa-sinensis and used as adulterant in the market. Hence, the morphological, Micro-morphological and powder microscopical studies on dried flowers of Hibiscus rosa-sinensis and Rhododendron arboreum was carried out and reported. Objective: To identify the dried flowers of Hisbiscus rosa-sinensis macro-microscopically and to differentiate it from adulterant Rhododendron arboreum. Methods: The morphology and powder microscopy were observed following standard methods and photographed. Results: The colour, taste, arrangement and appearance of calyx, corolla and stamen, trichomes, calcium oxalate crystals, sclereids, oil globules and pollen grains are found to be differentiating diagnostic characters in raw drug/powdered form of dried flowers of Hibiscus rosa-sinensis and Rhododendron arboreum. Conclusion: The finding of present study is helpful in standardization of formulation consists of Hibiscus rosa-sinensis as ingredient in their powdered form and also for authentication/identification of dried flowers of Hibiscus rosa-sinensis.

Background: Santalum album L. (Fam. Santalaceae) is a small evergreen tree distributed in South India mainly on the Deccan plateau, especially in Mysore and Tamil Nadu. The heartwood is highly prized and medicinally useful; Santalum album is one of the ingredients in many Ayurvedic and Siddha formulations. Objective: The present study brings out macro-microscopic atlas on heartwood of medicinal plant Santalum album L. Materials and Methods: Sections and powder were observed and photographed under different magnifications with the help of Olympus BX51 Microscopic unit fitted with Olympus Camera. Results: Macroscopically odour and taste, microscopically tyloses, fibres, tailed pitted vessels, uni and biseriate medullary rays, brownish content and oil globules are the unique diagnostic characters reported. Conclusion: The finding of the present study is believed to be helpful in identifying the correct botanical source of the plant in crude form and also standardization of herbal formulation containing sandalwood as ingredient.

Introduction: Comparative powder microscopic and HPTLC studies were carried out on stem barks of Symplocos racemosa Roxb. and Symplocos crataegoides Ham. to differentiate its identity in Ayurvedic formulations. Method: Powder microscopic and HPTLC studies of these barks were undertaken on a comparative basis and results are reported in this paper. The authentic samples are cleaned, powdered and passed through sieve No. 80. A few mg of powder was stained with saffranin, Toluidine blue and Iodine and photographed under different magnifications with the help of NICKON Labphot -2. HPTLC studies were followed by Sethi and Wagner et al method. Results: The colour, taste, cork cells, fibres, sclereids, starch grains, calcium oxalate crystals, number of spots and Rf values of HPTLC are found to be differentiating diagnostic characters in powdered form of S. racemosa and S. crataegoides. Conclusion: The findings of the present study is believed to be helpful in standardization of Ayurvedic formulation containing stem bark of S. racemosa and S. crataegoides as ingredients in powder form. The study sets the specific microscopic protocol and HPTLC finger print of the two drugs and may lead to global acceptance and reputation of the Ayurvedic system.

Context: The stem barks of the plant Symplocos crataegoides Buch.-Ham. ex D. Don (syn. Symplocos paniculata (Thunb.) Miq.), Fam. Symplocaceae is extensively used in Indian medicine under the names of Lodhra/Patikalodhra. Mainly it is used to cure uterine complaints, vaginal and menstrual disorders. Aim: To investigate the phytochemicals from the n-hexane extract of the stem bark of Symplocos crataegoides Buch.-Ham. ex D. Don., using GC-MS analysis. Materials and Methods: Stem bark of S.crataegoides was extracted by Soxhlet extraction method using n-hexane. The extract was injected by splitless injection mode into the GC MS 5975 C Agilent equipped with a QP- 5000 (quadrupole) Gas Chromatography - Mass Spectrometer. Results: Identification of 57 compounds from n-hexane extract. Those compounds were identified by close matches with standard MS spectra and compared with NIST - 11 and WILEY library data. Undecane (7.51\%) was found as major compound followed by Isopropyl myristate, Dodecane, 1,2,4-trimethyl-benzene, Octacosane, 2-methyl-decane, 2-ethyl-1,2-dimethyl-benzene, 1,2,3,5- tetramethyl-benzene etc., other constituents were found to be in traceable quantities. Conclusion: GC-MS analysis of S. crataegoides revealed certain interesting facts of presentation of various phytoconstituents in the stem bark. The presence of various phytoconstituents contributes to the medicinal activity of the plant.
