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.
