The aerial part of the plant Scutellaria intermedia Popov yielded five glucuronides, three of which were identified as chrysin 7-O-β-D-glucuronide, wogonin 7-O-β-D-glucuronide, and baicalein 7-O-β-Dglucuronide (baicalin). IR, UV, PMR, and 13C NMR spectral data and acid hydrolysis of the two new glucuronides established their structures as 5,7,2′-trihydroxyflavone 2′-O-β-D-glucuronopyranoside (4) and
植物 Scutellaria intermedia Popov 的地上部分产生了五种葡糖苷酸,其中三种被鉴定为白杨素 7-O-β-D-葡糖苷酸、汉黄芩素 7-O-β-D-葡糖苷酸和黄芩素 7-O-β-D-葡糖苷酸(黄芩苷)。两种新葡糖苷酸的 IR、UV、PMR 和 13C NMR 光谱数据和酸水解确定它们的结构为 5,7,2'-三羟基黄酮 2'-O-β-D-吡喃葡萄糖苷 (4) 和 scutevulin 2'-O -β-D-吡喃葡萄糖醛酸苷 (5)。
