In the ongoing phytochemical studies the roots of Medicinal plant known as Indigofera heterantha were investigated phytochemicaly in order to explore its medicinal potential. The ethyl acetate fraction was subjected to column chromatography which resulted in the isolation and purification of two new source compounds known as β-sitosterol (1) and Stigmasterol (2). The structures of these compounds were established by using Mass Spectrometry. The structures of these compounds were further authenticated by comparison with the literature data. The isolated pure compounds were screened for antidiabetic and membrane stabilizing activities. The antidiabetic activity of β-sitosterol (1) was measured on the basis of the glucose uptake in yeast cells. The results obtained revealed that β-sitosterol (1) exhibited significantly antidiabetic activity at all glucose concentrations with minimum increase 66.48% at 10µg/ml and maximum increase 74.46% at 80μg/ml glucose concentration. The Stigmasterol (2) showed good membrane stabilizing activity in HRBC, the minimum stabilization 62.74% at 10μg/ml and maximum stabilization 65.19% at 40μg/ml. These results showed that this plant is very important from medical point of view and it needs further phytochemical investigation to explore its hidden medicinal potential.
The current study was carried out to investigate the anti-inflammatory activity of the I. heterantha roots using membrane stabilizing assay by HRBC. The n-hexane fraction showed minimum stabilization 25.44% at 100μg/ml and maximum stabilization 55.61% at 400μg/ml while the EtoAc fraction showed minimum stabilization 48% at 100 μg/ml and maximum stabilization 71.88% at 400 μg/ml as compared to standard drug 64.70% at 100 μg/ml and 92.29% at 400μg/ml. These results revealed that this plant is very important from medicinal point of view and it needs further phytochemical exploitation to isolate phytochemical constituents having anti-inflammatory activity.
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.
