黄酮醇糖苷与茶树品种适制性关系
发布时间：2018-07-16 15:52
【摘要】：对不同加工适制性的18个茶树品种春季茶叶中10种黄酮醇糖苷进行了超高效液相色谱-四极杆-飞行时间质谱联用检测,并计算了葡萄糖苷化黄酮醇与半乳糖苷化黄酮醇的比值。结果发现相比于适制绿茶的茶树品种,适制红茶品种茶叶中黄酮醇葡萄糖苷化水平较高,而半乳糖苷化水平较低。山柰酚-3-葡萄糖苷含量、山柰酚-3-葡萄糖酰芸香糖苷含量、山柰酚-3-葡萄糖苷/山柰酚-3-半乳糖苷比值、槲皮素-3-葡萄糖苷/槲皮素-3-半乳糖苷比值、杨梅素-3-葡萄糖苷/杨梅素-3-半乳糖苷比值在不同适制性品种间具有显著性差异(P0.05)。其中山柰酚-3-葡萄糖苷含量和山柰酚-3-葡萄糖苷/山柰酚-3-半乳糖苷比值差异极显著(P0.001),对于绿茶适制性品种和红茶适制性品种的判断准确率分别为100%和83%,具有作为指导茶树品种适制性生化指标的可能。
[Abstract]:Ten kinds of flavonol glycosides from 18 tea varieties with different processing suitability were detected by ultrahigh performance liquid chromatography-quadrupole time-of-flight mass spectrometry. The ratio of glucoside flavonol to galactoside flavonol was calculated. The results showed that the level of flavonol glucoside was higher and galactosylation was lower than that of tea varieties with suitable green tea. Kaempferol-3- glucoside content, kaempferol-3-glucoylrutin content, kaempferol-3-glucoside / kaempferol-3-galactoside ratio, quercetin-3-glucoside / quercetin-3-galactoside ratio, The ratio of myricetin-3-glucoside / myricetin-3-galactoside was significantly different among different suitable varieties (P0.05). The content of kaempferol -3-glucoside and the ratio of kaempferol -3-glucoside to kaempferol -3-galactoside were significantly different (P0.001). The accuracy of judgement for suitable varieties of green tea and black tea were 100% and 83%, respectively. In order to guide the tea varieties suitable biochemical indicators.
