2种花色的薰衣草花色苷成分分析

Anthocyanin in Lavender of Two Flower Colors:Analysis of Compositions

为明确2种不同花色薰衣草间花色苷成分及含量差异性,探索薰衣草花色与花色苷的相关性。以‘新薰二号’(蓝花)和‘YXA-05’(白花)2种薰衣草花器官为研究材料,利用超高效液相色谱-四极杆飞行时间质谱(UPLC-Q-TOF/MS)联用技术测定2种薰衣草花器官中花色苷的成分及含量。结果表明,‘新薰二号’和‘YXA-05’2种薰衣草花冠中总花色苷含量分别为42.24μg/g和35.96μg/g,均含有6类花色苷,分别为矢车菊素、芍药花素、飞燕草素、矮牵牛素、锦葵素和天竺葵素。其中‘新薰二号’含有39种花色苷,‘YXA-05’含有37种花色素苷,‘新薰二号’含有6种‘YXA-05’中不存在的花色苷,而‘YXA-05’含有4种‘新薰二号’中不存在的花色苷。可见,2种薰衣草中花色苷的种类丰富,且成分及含量存在差异,薰衣草花冠的颜色与其花色素苷的成分和含量有关。

The aim is to clarify the composition and content differences of anthocyanin between two kinds of lavender varying in flower color,and to explore the relevance between lavender flower color and anthocyanin.The flower organs of‘Xinxun No.2’(blue flower)and‘YXA-05’(white flower)were used as research materials.The composition and content of anthocyanins in flower organs of the two lavender varieties were determined by using the combination technology of ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF/MS).The result showed that the total anthocyanin content in‘Xinxun No.2’and‘YXA-05’was 42.24μg/g and 35.96μg/g respectively,and both two varieties contained 6 types of anthocyanin,including cyanidin,peonidin,delphinidin,petunidin,malyidin and pelargonidin.There were 39 types of anthocyanin in‘Xinxun No.2’,and 37 types of anthocyanin in‘YXA-05’.‘Xinxun No.2’contained 6 types of anthocyanin that were not found in‘YXA-05’,while‘YXA-05’contained 4 types of anthocyanin that were not found in‘Xinxun No.2’.It was indicated that in these two lavender varieties,anthocyanin was rich in types and differed in composition and content.The flower color of corolla was related to the composition and content of its anthocyanin.
