Studies on chemical constituents in Guizhi Fuling Capsule (VII) / 中草药

Objective To study the chemical constituents from the n-butanol extract of Guizhi Fuling Capsule. Methods The chemical constituents were isolated and purified by multiple chromatographic methods. Their structures were identified on the basis of the spectral data and physicochemical properties. Results Five compounds were identified as 3'-O-galloylsucrose (1), 4'-O-galloylsucrose (2), 6'-O-galloylsucrose (3), 1'-O-galloylsucrose (4), and 1,2,3,4,6-pentagalloylglucose (5). Conclusion Compounds 1-5 are isolated from Guizhi Fuling Capsule for the first time, and compound 1 is a new compound. Compounds 1-5 inhibited calcium influx in uterine smooth muscle cells of primary mice.
