The ethanolic extract of the seeds of Trifolium alexandrinum afforded a new naturally occurring compound identified as methyl-alpha-glucose. The known compounds quercetin, kaempferol, apigenin 7-O-beta-D-glucoside and the nucleoside xanthosine were also isolated. The isolated compounds were identified by spectroscopic (UV
Induction of cancer-cell differentiation is an alternative approach for cancer chemotherapy. There are numerous studies that diets containing an abundance of fruits and vegetables have protection against cancers, and the main agents thought to provide such protective effect are flavonoids.

To study the flavonoids constituents of Trachelospemum jasminoides. The compounds were separated and purified by column chromatography with silica gel, and identified by IR, MS, NMR and 2D-NMR. Six flavonoids were identified as apigenin (I), apigenin 7-O-beta-glucoside (II), apigenin 7-O-beta-neospheroside
