Study on Separation and Purification of Chlorogenic Acid from Honeysuckle Flower by Macroporous Resin
摘要
Abstract
The tests of single factor, orthogonal and verification to separate and purify chlorogenic acid from honeysuckle crude extracts by NKA-2, D1400, polyamide, HP2MGL, ADS-21, D101 and AB-8 seven macroporous resin were carried out in sequence, and the best processing parameters were optimized based on the adsorption and desorption results. The results showed that NKA-2 was the best resin, whose static saturated adsorption capacity was 212. 17 mg/g, and desorption rate by 90% ethanol reached 81.4%. The best processing parameters for separating and purifying chlorogenic acid from honeysuckle crude extracts by NKA-2 resin were as follows: sample concentration: 4 g/L, sample volume: 3.5 BV, sample flow rate: 3 BV/h, elution ethanol concentration: 80% , elution volume: 3 BV, and elution flow rate: 1 BV/h. Under the optimal conditions, the yield rate of chlorogenic acid reached 85.79% , and its purity was 45.50%. When using sample concentration of 3 g/L, sample volume of 4. 5 BV, sample flow rate of 2 BV/h, elution ethanol concentration of 80% , elution volume of 3 BV and elution flow rate of 3 BV/h, the purity of chlorogenic acid reached 53.07% , and its yield was 73.33%. Comparing with the current separating and purifying process of chlorogenic acid from honeysuckle crude extracts, the optimized process has better practical and reference value.关键词
