  • This study presents a detailed pharmacognostical study of the underground portion of the crude drug Sphaeranthus indicus Linn. (Asteraceae), an important plant in the Indian system of medicine. The root and stolon were studied using procedures of light, conofocal microscopy, WHO recommended-physicochemical determinations, and authentic phytochemical procedures. The physicochemical, morphological, and histological parameters presented in this paper may be proposed as parameters to identify and establish the authenticity of S. indicus root and stolon.

  • The methanol extract of seeds of Swietenia macrophylla King. (MESM) was studied for its antidiabetic activity in streptozotocin induced diabetic rats. It was principally aimed to correlate the efficacious role of MESM on reduction of oxidative state associated with diabetes. The extract was found to be potent antidiabetic evidenced by significant reduction of blood glucose level in diabetic rats (47.96% reduction of blood glucose level, at 300 mg/kg, on day 10). It was found that, MESM at 300 mg/kg, significantly decreased TBARS (35.03 and 22.22%) whilst increased GSH (86.75 and 31.45%), SOD (93.05 and 45.88%) and CAT (56.99 and 68.46%) levels in liver and kidney respectively in diabetic rats.

  • This paper presents a detailed pharmacognostical study of the plant drug Hybanthus enneaspermus (L.) F. Muell (Violaceae), an important drug in the Indian system of medicine. The leaf and stem samples were studied using procedures of light, confocal microscopy, WHO recommended physico-chemical determinations and authentic phytochemical procedures. The physico-chemical, morphological, and histological parameters presented in this paper may be proposed as parameters to establish the authenticity of H. enneaspermus and may possibly help to differentiate the drug from its adulterants.
