Phytochemical And Bioactivity Studies Of Strobilanthes Crispus L
Phytochemical investigation of the hexane, dichloromethane and methanol extracts of the leaves of Strobilanthes crispus has led to the isolation of nine compounds, comprising 1-heptacosanol (c-1), lignoceric acid (c-2) and stigmasterol (c-3) from the hexane extract, a mixture of four esters of β-amy...
