在培养的Ｗｉｓｔａｒ大鼠心室肌细胞上，用膜片钳法证明齐墩果酸型人参皂甙单体Ｒ０２００μｍｏｌ·ｍＬ－１对Ｌ，Ｂ，Ｔ三型钙通道的单通道活动均无影响；用电子自旋共振法证明Ｒ０３０μｍｏｌ·ｍＬ－１不能抑制黄嘌呤０．４２ｍｍｏｌ·Ｌ－１－黄嘌呤氧化酶５．３ｎｍｏｌ·Ｌ－１所致的自由基含量增多。确切证明Ｒ０既无钙通道阻滞作用，也无抗自由基作用。
On the cultured Wistar rat ventricular myocytes, the patch-clamp method was used to prove that single-channel activities of L-type, B-type and T-type calcium channels were not affected by R0200μmol · mL-1 of oleanolic acid type ginsenoside. Electron spin resonance method proved R030μmol · mL-1 can not inhibit xanthine 0.42mmol · L-xanthine oxidase 5.3nmol·L-1 induced by free radicals increased. It is proved that R0 has neither calcium channel block effect nor anti-free radical effect.
