为分析夏黑葡萄藤在放置过程中化合物的种类、含量变化规律及机制。本研究应用超高效液相色谱仪联用四级杆串联飞行时间质谱仪(UPLC-Q-TOF-MS)在负离子模式下对夏黑葡萄藤中主要化学成分进行定性分析;采用高效液相色谱仪(HPLC)分析夏黑葡萄藤在放置过程中化合物的含量变化趋势。通过液质联用分析方法初步鉴定出夏黑葡萄藤中的黄酮类化合物主要有儿茶素、表儿茶素、槲皮素、槲皮素-3-O-半乳糖苷、petunidin 3-O-glucoside、trans-scirpusin A;芪类化合物为反式白藜芦醇、ε-葡萄素、vitisin B、miyabenol C;苯丙素类化合物为反式咖啡酸。葡萄藤在剪枝后放置过程中,反式白藜芦醇与ε-葡萄素在0~20...

To analyze the variety and content of the compounds change rules during grapevines of Summer Black storage.The main chemical constituents in the grapevine of Summer Black were qualitatively analyzed by ultra high performance liquid chromatography(UPLC-Q-TOF-MS)under the negative ion mode,and the change trend of the chemical constituents in the grape vine of Summer Black during storage was analyzed by high performance liquid chromatography(HPLC).The main flavonoids in grape vine were identified by LC-MS as catechin,epicatechin,quercetin,querceti...
