绞股蓝及其制剂中总皂苷不宜用人参皂苷R_(bl)对照测定含量

Not proper for the determination of GinosideR_(b1) in Gynostemma pentaphyllum (Thunb.)Makin and its preparation

绞股蓝及其制剂中总皂苷的含量 ,大多以人参皂苷Rbl为对照品进行测定。目前 ,使用高效液相色谱法测定人参皂苷Rbl含量 ,未见报道。本文采用高效液相色谱法对人参皂苷Rbl进行含量测定 ,结果表明 :绞股蓝中人参皂苷Rbl的含量极低 ,用高效液相色谱法测定人参皂苷Rbl含量难以进行。

The content of Ginoside R b1 in Gynostemma pentaphyllum (Thunb.)Makin was too low. It is difficult to determinate Ginoside R b1 in Gynostemma pentaphyllum(Thunb.)Makin and its preparation by HPLC. It was reported that Ginoside R b1 in Gynostemma pentaphyllum (Thunb.)Makin was not found by TLC identification.
