运用超声波提取方法对柽柳植株中总黄酮的空间分布、年变化及不同柽柳家系总黄酮的变化情况进行了研究。结果表明:柽柳植株各部位都含有黄酮类化合物,但总黄酮含量不同,其中根皮和茎皮含量最高达到17.949mg/g和17.060mg/g,显著(P<0.01)超过其他部位,去皮茎含量最低为5.233mg/g;柽柳茎和嫩茎叶中总黄酮含量各月间存在显著差异,在7月达最高值显著(P<0.01)超过5月和6月;柽柳家系间地上部分总黄酮含量的差异显著(P<0.05),9个家系的平均值为20.232mg/g,变异系数为49.6%,滨1012和滨1018总黄酮含量最高,与其它家系达到极显著差异水平(P<0.01)。
The ultrasonic extraction method was used to study the spatial distribution of flavonoids in Tamarix chinensis and the changes of flavonoids in different species of Tamarix chinensis. The results showed that all parts of Tamarix spp. Contained flavonoids, but the contents of total flavonoids were different. The content of root bark and bark reached 17.949mg / g and 17.060mg / g respectively, which was significantly (P <0.01) The content of total flavonoids in stems and leaves of Tamarix chinensis varied significantly from month to month, reaching the highest value in July (P <0.01), exceeding that in May and June. The aboveground parts The average content of total flavonoids was 20.232mg / g, the coefficient of variation was 49.6%, the content of total flavonoids in Bin 1012 and Bin 1018 was the highest, and reached the extremely significant difference with other families (P <0.05) <0.01).
