甘肃不同产地红芪中主要功效成分及有益元素含量的研究
目的 比较甘肃省渭源县、漳县、宕昌县、陇西县和武都县等5个产区的红芪样品中主要功效成分总黄酮、总皂甙、总多糖以及9种有益无机元素含量, 并分析这些成分与产地之间的关系。方法 参照保健食品中功效成分的检测方法对红芪中总黄酮、总皂甙和总多糖的含量进行测定; 参考《国家食品污染物和有害因素风险监测工作手册》方法测定红芪中无机元素的含量。结果 所采5个产区的红芪样品中总黄酮含量漳县最低(0.935 mg/100 g), 渭源县最高(3.115 mg/100 g); 总多糖含量宕昌县最低(0.078 mg/g), 陇西县最高(0.462 mg/g); 总皂甙含量渭源县最低(1.503 mg/100 g), 陇西县最高(1.600 mg/100 g)。Ca和Mg的含量均是武都县较高, 分别为6960.389 mg/kg和2526.444 mg/kg; 比较其余元素发现, Sr在陇西样品中含量较高, 均值为82.017 mg/kg, 宕昌县样品含量最低, 均值为31.500 mg/kg。5个县区之间红芪中总黄酮与总多糖含量含量有统计学差异(P0.05)。Mg、Mo、Sr在5个县区之间存在统计学差异(P0.05)。结论 不同产区红芪中总黄酮、总皂甙、总多糖含量和9种有益无机元素含量存在一定的差异, 武都县和陇西县样品的质量优于渭源、漳县和宕昌等3个县区, 可为红芪资源的进一步开发利用提供参考依据。
Objective To compare the main efficacy components such as total flavonoids, total saponins, total polysaccharides and 9 kinds of beneficial inorganic element content of Hedysari radix from 5 different origins in Gansu, including Weiyuan, Zhang, Dangchang, Longxi and WuDu county and analyze the relationship between the content and the origin areas. Methods The content of total flavonoids, total saponins and total polysaccharides was determined according to the detection methods of functional components in health foods. The content of inorganic elements in Radix Hedysari was determined according to the National manual for risk monitoring of food contaminants and harmful factors. Results Total flavonoids content in Radix Hedysari samples from 5 origin areas was the lowest (0.935 mg/100 g) in Zhang county and the highest (3.115 mg/100 g) in Weiyuan county. Total polysaccharide content in Dangchang was the lowest (0.078 mg/g), and in Longxi was the highest (0.462 mg/g). The total saponin content was the lowest (1.503 mg/100 g) in Weiyuan county and the highest (1.600 mg/100 g) in Longxi county. The samples from Wudu county had higher content of Ca and Mg, with 6960.389 mg/kg and 2526.444 mg/kg, respectively. Compared with other elements, the content of Sr in Longxi sample was higher, with 82.017 mg/kg in average, which was the lowest in Dangchang county, with 31.500 mg/kg in average. The content of total flavonoids and total polysaccharides in Hedysari radix were significantly different among the 5 counties (P0.05). There were significant differences in Mg, Mo and Sr among the 5 counties (P0.05). Conclusion There are some differences in the content of total flavonoids, total saponins, total polysaccharides and 9 kinds of beneficial inorganic elements in different origin areas of Hedysari radix. The quality of samples in Wudu and Longxi county is better than those in Weiyuan, Zhang and Dangchang county, which can provide reference for further development and utilization of Hedysari radix resources.
