- W2377987564 abstract "Objective To optimize the technology for separation and purification of total alkaloids from Uncariae Ramulus cum Uncis by cation exchange resin.Methods The elution and absorption rate and content of mitrinermine and total alkaloids were used as indexes through comparing different elution agents to optimize the purifying conditions of total alkaloids.Results The optimum condition was passing through the 001×7 hydrogen cation exchange resin column(r:h = 1:8) at the rate of 6 BV/h in reverse direction,then the resin column was flushed with water at the rate of 6 BV/h to neutral in forward direction.At last,the column was eluted at the rate of 8 BV/h to obtain alkaloids with 5% NaCl in 50% alcohol,the content of mitrinermine was 13.9% and the content of the total alkaloids was 47.6%;The elution ratio of mitrinermine was 88.2% and total alkaloids was 89.9%.Conclusion Separation and purification of the total alkaloids from Uncariae Ramulus cum Uncis with 001×7 hydrogen cation exchange resin could achieve satisfactory results,and it has wide application prospects in industry." @default.
