Аннотация
From the root of Scutellaria prostrata JACQ. ex BENTH., five compounds (I-V) were isolated, together with three known glycosides of phenylethanoid (IV-VIII) and sixteen known flavonoids (IX-XXIV). On the basis of chemical and spectral evidence, I-V were identified as 5, 6, 2', 6'-tetrahydroxy-7, 8-dimethoxyflavone, 5, 6, 2'-trihydroxy-7, 8, 6'-trimethoxyflavone, 5, 7, 2'-trihydroxy-8-methoxyflavone 7-O-β-D-glucuronopyranoside, 2-(3-hydroxy-4-methoxyphenyl)ethyl 1-O-β-D-glucopyranoside and 2-(3-hydroxy-4-methoxyphenyl)ethyl 1-O-β-D-(4-O-feruloyl)glucopyranoside, respectively. Compound II has already been synthesized.
