Description
Summary:The study of the chemical constituents of the whole plant of Geranium wallichianum (Geraniaceae) has resulted in the isolation and characterization of six compounds. These six compounds were identified as ursolic acid (1), β-sitosterol (2), stigmasterol (3),b-sitosterol galactoside (4), herniarin (5), and 2,4,6-trihydroxyethylbenzoate (6) which were isolated for the first time from Geranium wallichianum. The above compounds were individually identified by spectroscopic analyses and comparisons with reported data. The antioxidant potential of Geranium wallichianum extracts has been investigated by DPPH radical scavenging assay and EtOAc extract was found to be most potent with IC50 19.05 ug/mL.
