The purpose of this study is to investigate the central nervous system (CNS) depressant and analgesic activities of the ethanol extract of Scutia myrtina (EESM) (Family: Rhamnaceae) in Swiss albino mice. To evaluate the CNS depressant activity by using the methods such as general behavior, exploratory behavior, muscle relaxant activity and phenobarbitone sodium-induced sleeping time were studied. Analgesic effect of EESM was evaluated in acetic acid induced writhing and hotplate tests. The results revealed that the EESM at the dose of 200 and 300 mg/kg caused a significant reduction in the spontaneous activity (general behavioral profile), remarkable decrease in exploratory behavioral pattern (Y-maze and head dip test), a reduction in muscle relaxant activity (rotarod and traction tests), and also significantly potentiated phenobarbitone sodium-induced sleeping time. The EESM also produced significant analgesic activity in both models at the dose of 200 and 300 mg/kg. Further, the EESM potentiated the morphine and aspirin induced analgesic in mice. The results suggest that EESM exhibit CNS depressant and analgesic activity in tested animal models.
Tagetes erecta(African marigold) has various medicinal values. The present study has been undertaken to evaluate the effects of extracts of the fresh leaves and flowers of Tagetes erecta on oral ulcer models in Wistar albino rats. The anti-ulcer activity of the extracts of tagetes erecta (2.5% and 5%) was compared between the leaf and flower and also with the standard drug, Triamcinolone. Phytochemical screening of plant extract, extract action on oral ulcer and histopathology analysis were carried out. Tagetes erecta leaf and flower extracts have showed the presence of alkaloids, flavonoids, and carotenoids. Results showed that Tagetes erect leaf extract showed significant oral ulcer protective activity (83.6%) when compared with the standard drug Triamcinolone. In the present work, it can be concluded that the hydro alcoholic leaf and flower extractHistopathologys of Tagetes erectagel have better potential against oral ulcer which supports the traditional claims in folklore medicine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
