摘要:
The paper deals with the determination of ginsenoside-Rgl in Radix Notoginseng(l), the dried roots of P. notoginseng, and Sanqi Oral Liquid(2).The calibration curves for ginsenoside-Rgl was linear over the range of 4 ug~20 ug. The regression equation of peak areas against weights was Y=121475X+8636(r=0.9999). The recovery assay of ginsenoside-Rgl was carried out by adding the standard compounds(2.0-4.0mg) to (2),which was treated according to the procedure described in preparation of sample solutions. The average recovery was 98.9%, its RSD being 1.6%(n=5). The precision of the chromatographic determination was evaluated by injecting the same standard sample repeatedly, its RSD being 0.83%. The method was simple, accurate, sensitive and reliable.
