Background: Rohitaka (Tecomella undulata (Sm.) Seem.) has been considered as threatened and listed as rare at international level (IUCN, 2000). In Ayurveda classics, Rohitaka is described as Yakritpleehgulmodarhara (useful in liver and spleenic disorders). Rhododendron arboreum Sm. is used by folklore practitioners for treatment of Jaundice and marketed as Rohitaka in Nepal. Aim: To evaluate Rhododendron arboreum Sm. as an effective pratinidhi dravya (substitute) in abhava (absence) of Rohitaka (Tecomella undulata (Sm.) Seem.) with special reference to hepatoprotective activity in paracetamol induced hepatotoxicity in rats. Materials and Methods: In the present study, hepatoprotective effect of Choorna (powder) and Kwatha (decoction) of Rhododendron arboreum Sm. and Tecomella undulata (Sm.) Seem. (Choorna-0.54 g/kg body wt. and Kwatha- 4.32 ml/kg body wt. p. o. for 10 days along with paracetamol toxicant 3 g/kg body wt. p. o. on 6th and 8th day) were investigated against paracetamol induced hepatotoxicity. Silymarin (100 mg/kg body wt.) was used as standard hepatoprotective reference drug. Statistical Analysis Used: The obtained data were analyzed by ANOVA with Dunnet{\textquoteright}s multiple {\textquoteleft}t{\textquoteright} test and level of p\<0.05 was considered as statistically significant. Results: Paracetamol treatment led to elevated levels of liver marker enzymes and disorientation in histological observations which were significantly reversed by treatment with Rhododendron arboreum Sm. and Tecomella undulata (Sm.) Seem. dependent on dosage forms. Conclusion: The study revealed that both the drugs have similar hepatoprotective effect and thus Rhododendron arboreum Sm. as {\textquotedblleft}Abhava Pratinidhi Dravya{\textquotedblright} for Tecomella undulata (Sm.) Seem. with special reference to hepatoprotective activity is justified.

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.
