LC-ESI-MS/MS profile accompanied by the structure of compounds identified from stem extract. Fig. 2D (SHE) was predicted to contain stigmastan-3,6-dione (3). Fig. 2E (SEAE) was predicted to contain lucialdehyde B (8), and Fig. 2F (SEE) was predicted to contain the compounds 5,2′,6′-trihydroxy-7,8-dimethoxy-flavone-2′-O-β-D-glucopyranoside (13), 5,7,3′,5′-tetrahydroxyflavanone (14), and quercetin (15).
