摘要
以“连桕1号”“云台红桕”和“云台金桕”为研究对象,利用超高效液相色谱-质谱联用技术定性定量分析其叶片转色前和转色后花青素成分与含量。结果表明:3个乌桕品种中共检测到14种花青素物质,分别为锦葵花素、天竺葵色素、飞燕草素、芍药色素、矢车菊素半乳糖苷、异鼠李素、矢车菊素、矢车菊素双葡萄糖苷、矮牵牛色素、槲皮素、芦丁、原花色素B4、双聚原矢车菊苷元和山奈酚,其中矢车菊素半乳糖苷、芦丁为3个乌桕品种叶片转色后共有的主体成分。矢车菊素半乳糖苷是“云台红桕”转色后叶片呈现红色的主要色素成分;芦丁是“云台金桕”叶片变黄的主要原因。花青素类型主要为芦丁类、矢车菊素类和其他类。叶片转色后矢车菊素类含量由高至低依次为“连桕1号”>“云台红桕”>“云台金桕”,叶片转色后芦丁类含量由高至低依次为“云台金桕”>“连桕1号”>“云台红桕”。
Using“Lianjiu No.1”,“Yuntaihongjiu”and“Yuntaijinjiu”as research objects,the anthocyanin components and content of their leaves before and after color transformation were qualitatively and quantitatively analyzed using ultra-high performance liquid chromatography-mass spectrometry technology.The results showed that a total of 14 anthocyanins were detected in leaves from three varieties,including malvidin,pelargonidin,delphinidin,peonidin,cyanidin 3-galactoside,isorhamnetin,cyanidin,cyanidin 3,5-diglucoside,petunidin,quercetin,rutin,procyanidin B4,procyanidin B2 and kaempferol.Cyanidin 3-galactoside and rutin were the main anthocyanin components of three varieties.The cyanidin 3-galactoside was the main pigment component for the red colored leaves of“Yuntaihongjiu”;rutin was the main reason for the yellow colored leaves of“Yuntaijinjiu”.The main anthocyanins types in three varieties were rutins,cyanidins and others.After the color change of leaves,the content of cyanidins from high to low was in order of“Lianjiu No.1”>“Yuntaihongjiu”>“Yuntaijinjiu”.After the color change of leaves,the content of rutins from hight to low was in order of“Yuntaijinjiu”>“Lianjiu No.1”>“Yuntaihongjiu”.
