摘要：以金花茶、小果金花茶、扶绥金花茶、龙州金花茶和陇瑞金花茶等五种金花茶组植物为试验材料,按照CIE L*a*b*表色系法测量其花色,利用超高效液相色谱-四极杆-飞行时间质谱(UPLC-Q-TOF-MS)联用技术定性定量分析其花中类黄酮成分与含量,运用多元线性回归方法研究花色与类黄酮成分之间的关系。结果表明:5种金花茶组植物花中共检测到8种类黄酮成分,其中天竺葵素-3-O-葡萄糖苷(Pg3G)、木犀草素-7-O-芸香糖苷(Lu7R)、芸香柚皮苷和圣草素为金花茶组植物中首次发现;槲皮素-3-O-葡萄糖苷(Qu3G)、槲皮素-7-O-葡萄糖苷(Qu7G)、槲皮素-3-O-芸香糖苷(Qu3R)和山柰酚-3-O-葡萄糖苷(Km3G)为扶绥金花茶和小果金花茶中首次发现;金花茶花中类黄酮成分总量最高,其次是扶绥金花茶和小果金花茶,陇瑞金花茶和龙州金花茶较低;金花茶和小果金花茶主要类黄酮成分为Qu3G、Qu3R和Pg3G,扶绥金花茶为Qu3G和Qu7G,陇瑞金花茶和龙州金花茶为圣草素和芸香柚皮苷; Qu3G和Qu3R是决定金花茶组植物花瓣呈现黄色的主要成分,圣草素与花瓣红晕显著正相关,Pg3G影响花色鲜艳程度。
The flower colors,flavonoid components and contents in five species of Camellia section Chrysantha,including Camellia nitidissima,C.microcarpa,C.achrysantha,C.longruiensis and C.longzhouensis,were measured.The flower colors were measured by CIE L*a*b*scale,and flavonoid components and contents were measured by ultra-performance liquid chromatography quadrupole-time-of-flight mass spectrometry.The relationship between flower colors and flavonoid components was explored by multiple linear regression analyses.Eight flavonoids were detected in the five species.The flavonoids including pelargonium-3-O-glucoside(Pg3 G),luteolin-7-O-rutinoside(Lu7 R),narirutin and erodcyol were identified in the five species for the first time.The quercetin-3-O-glucoside(Qu3 G),quercetin-7-O-glucoside(Qu7 G),quercetin-3-Orutinoside(Qu3 R)and kaempferol-3-O-glucoside(Km3 G)were identified in C.microcarpa and C.achrysantha for the first time.Among the five species,the total flavonoid content of C.nitidissima was the highest,followed by C.achrysantha and C.microcarpa,and that of C.longruiensis and C.longzhouensis were lower.Qu3 G,Qu3 R and Pg3 G were the main flavonoid components in C.nitidissima and C.microcarpa.Qu3 G and Qu7 G were the main flavonoid components in C.achrysantha.Erodcyol and narirutin were the main flavonoid components in C.longruiensis and C.longzhouensis.We conclude that Qu3 G and Qu3 R were the important pigments determining the yellow coloring of petals of Camellia section Chrysantha.Erodcyol had a significantly positive correlation with red coloring of petals.Pg3 G affected the brilliance of flower colors.
