Chevalierinoside A: A new isoflavonoid glycoside from the stem bark of Antidesma chevalieri Beille (Euphorbiaceae)

Abstract : Chevalierinoside A (1), a new isoflavonoid glycoside determined as biochanin A 7-O-[a-L-rhamnopyranosyl-1→6-β-D-apiofuranosyl-1→2-β-D-glucopyranoside], together with the known friedelin (2), friedelan-3b-ol (3) and betulinic acid (4), were isolated from the stem bark of Antidesma chevalieri Beille. Their structures were established by direct interpretation of their spectral data, mainly TOF-HRESIMS, 1D-NMR (1H, 13C and DEPT) and 2D-NMR (COSY, ROESY, TOCSY, HSQC and HMBC), and by comparison with the literature.
