From the root of Scutellaria prostrata Jacq. ex Benth. five compounds (I-V) were isolated, together with three known glycosides of phenylethanoid (VI-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.
