REN Lingyan, et al. Content determination of Total Saponins from Rubus parvifolius L[J]. Journal of Chongqing Medical University, 2005,(6):854-856. DOI: 10.13406/j.cnki.cyxb.2005.06.021.
Objective; To establish a method for content determination of total saponins in Rubus parvifolius L.. Methods; Total saponins was determined by UV - VIS spectrophotometry after different extracts of the sample had been coloured. Results; The method was linear in the range of 22-176μg (r = 0.9997)
and the average recovery was 102. 1 %
RSDwas 2. 82% (n = 6). The content of total saponins was highest by the method of 70% ethanol reflux. Conclusion; The sample is stable after coloured. The method is sensitive and reliable
which may be used for the quality control of Rubus parvifolius L. .
