【摘要】 采用超声提取法对人参香皂中的人参总皂苷进行提取,溶剂萃取法对人参总皂苷进行纯化,用香草醛-高氯酸比色法对纯化后样品进行了人参总皂苷含量的测定,检测波长为540 nm。实验结果表明,香草醛-高氯酸比色法在0.02~0.24 mg内线性关系良好(r=0.999 5),平均回收率为96.04%,RSD为2.29%(n=5)。所测6种人参香皂中人参总皂苷的质量分数为1.72~9.66 mg·g-1。更多还原

【Abstract】 Ginseng- formulated toilet soap sample was extracted by ethanol under assistance of ultrasonic action.Then the extract was purified by extraction with a series of solvents.Total ginsenoside content in the purified extract sample was determined by vanillin- perchloric acid colorimetry with detection wavelength of 540 nm.Results showed that the relationship between the absorbance and the ginsenoside content displays good linearity within range of 0.02- 0.24 mg(r = 0.999 5) and average recovery rate was 96.04% with a relative standard deviation of 2.29%(n = 5).Determination test with samples of six kinds of ginseng- formulated toilet soap was carried out and the total ginsenoside content lies within 1.72- 9.66 mg·g- 1.更多还原
