通过气质和液质联用技术,对三种中草药植物虎杖、买麻藤和小叶买麻藤以及葡萄籽中白藜芦醇首先进行了定性研究;而后采用高压液相法对这四种植物的提纯液进行了定量研究,含量分别为53.00,36.18,32.69和30.63μg·g-1;其次对小叶买麻藤的藤茎进行了组织化学的定位研究,发现白藜芦醇在韧皮部中的含量为448.80μg·g-1,在木质部中为0μg·g-1,结果显示白藜芦醇主要存在于韧皮部中。 Through qualitative and liquid chromatography-mass spectrometry techniques, qualitative studies were first performed on the three Chinese herbal plants Polygonum cuspidatum, Maitake and Maitake, and resveratrol in grape seed; then the four plants were purified by high pressure liquid phase method. Quantitative studies were carried out on the liquids, the contents were 53.00, 36.18, 32.69, and 30.63 μg·g-1, respectively; secondly, the cane of Maitake ratoon was studied by histochemical localization and it was found that the content of resveratrol in the phloem was 448.80 μg·g-1, 0 μg·g-1 in the xylem, showed that resveratrol was mainly present in the phloem.
