从菊科植物灯盏花 Erigeron brevis capus中分得 4个黄酮苷类化合物 ,通过理化常数、光谱数据分别鉴定为灯盏乙素 (scutellarin, )、5 ,6 ,4′-三羟基黄酮 - 7- O-β- D-半乳糖醛酸苷 (5 ,6 ,4′- trihydroxy flavone- 7- O-β- D-galactonic acid, )、灯盏甲素 (4′- hydroxy baicalein- 7- O- β- D- pyrangluconate methyl ester, )和黄芩素 - 7- O- β- D-吡喃葡萄糖苷 (baicalein- 7- O-β- D - pyranglucose, )。其中 为新化合物 , 为首次从本植物中分得 Four flavonoid glycosides were isolated from Erigeron brevis capus, and identified as scutellarin, 5,6,4′-trihydroxyflavone-7-one by physicochemical constants and spectral data. -β-D-galactosidase (5,6,4’-trihydroxy flavone- 7-O-β-D-galactonic acid, ), chloramphenicol (4’-hydroxy baicalein- 7-O-β- D-pyranluconate methyl ester, ) and baicalein-7-O-β-D-glucopyranoside (baicalein-7-O-β-D-pyranlucose). Which is a new compound, it is the first time it has been obtained from this plant.
