摘要
目的探讨不同炮制方法对于黄芪制品中黄酮类及糖类成分的影响。方法将统一产地及批次的黄芪通过不同的炮制方式转变为酒黄芪、米黄芪、炒黄芪、盐黄芪及蜜黄芪,分析不同方式炮制的黄芪中含有的糖类及黄酮类成分的变化情况。结果黄酮类:酒黄芪中毛蕊异黄酮的含量相对于生黄芪明显增加;蜜黄芪中黄酮类成分含量明显下降,而盐黄芪、米黄芪对黄酮类成分的影响不明显。糖类:水溶性糖在不同炮制方式中的含量由高到低依次为生黄芪>米黄芪>酒黄芪>盐黄芪>炒黄芪;还原性糖:生黄芪>米黄芪>酒黄芪>盐黄芪>炒黄芪;多糖:酒黄芪>盐黄芪>炒黄芪>米黄芪>生黄芪,以酒炙黄芪最高。结论不同的炮制方式会对黄芪中的有效成分含量产生明显的影响,黄酮类以酒制增加最为明显,蜜制则下降明显;多糖类也亦酒制增加明显,而水溶性糖及还原性糖则通过炮制后含量下降,以盐黄芪下降最明显。
Objective To explore the effects of different processing methods on the components of flavonoid and sugar in astragalus propinquus.MethodsAstragalus propinquus （huangqi） of the same place of production and batch was processed via different methods into wine huangqi, rice huangqi, fried huangqi, salt huangqi and honey huangqi. Changes of sugar and flavonoid contained in huangqi processed by different methods were analyzed.Results Flavonoid： The content of calycosin in wine huangqi significantly increased compared to that in raw huangqi; the content of flavonoid in honey huangqi significantly reduced, and no significant changes of flavonoid were shown in salt huangqi and rice huangqi. Sugar： the contents of water-soluble sugars in different processing methods ranked from high to low were raw huangqi 〉 rice huangqi 〉wine huangqi 〉 salt huangqi 〉 fried huangqi; ranks of reducing sugar： raw huangqi 〉 rice huangqi 〉 wine huangqi 〉 salt huangqi 〉 fried huangqi; ranks of polysaccharide： wine huangqi 〉salt huangqi 〉 fired huangqi 〉 rice huangqi 〉 raw huangqi, and the highest content of polysaccharide was seen in wine-fried huangqi. ConclusionDifferent processing methods have significant effects on the content of active components in astragalus propinquus. Flavonoid is seen the most significant increase in wine huangqi, and the most significant decrease in honey huangqi; polysaccharide is seen the most significant increase in wine huangqi as well, and the contents of water-soluble sugars and reducing sugar decrease after the processing, with the most significant decrease in salt huangqi.
