摘要:

为明确紫薇属(Lagerstroemia)和黄薇属(Heimia)的花色成分,探讨属间远缘杂交获得黄色花紫薇的可能性,以8个紫薇属种和品种与2种黄薇属植物的花瓣为材料,利用英国皇家园艺学会比色卡测量花色表型参数,采用超高效液相色谱—电喷雾电离—串联质谱(UPLC-ESI-MS/MS)技术对花瓣中类黄酮代谢物进行了定性和定量分析。8个紫薇属种和品种的花色分为红色、紫色与白色3个色系,共检测到158种类黄酮代谢物;2种黄薇属植物花色均为黄色系,共检测到138种类黄酮代谢物。黄薇属花瓣中芹菜素-4-O-鼠李糖苷、芹菜素-O-葡萄糖-O-鼠李糖、木犀草素、木犀草素-7-O-芸香糖苷(黄酮类)、山奈酚-3-O-葡萄糖苷-7-O-鼠李糖苷、山奈酚-3-O-洋槐糖苷、山奈酚-3-O-芸香糖苷、山奈酚-3-O-葡萄糖苷、山奈酚-7-O-葡萄糖苷(黄酮醇类)的相对含量远高于紫薇属,推测是黄薇属植物花瓣呈黄色的主要色素。而紫薇属花瓣中共有的相对含量较低的类黄酮代谢物有32种,其红色系和紫色系花瓣中主要呈色色素为花青素苷,白色系花瓣中黄酮与黄酮醇类代谢物主要以木犀草素与槲皮素为苷元。类黄酮代谢途径的中间产物或最终物质积累量不同,是导致紫薇属与黄薇属植物花色差异的主要原因。

Abstract:

In order to clarify the pigment composition of Lagerstroemia and Heimia,and to explore the feasibility of obtaining Lagerstroemia cultivar with yellow petals by distant hybridization,petal colors of eight Lagerstroemia species and cultivars and two Heimia species were used in this research. The Royal Horticultural Society Color Chart(R.H.S.C.C.)was used for the measurement of the phenotype parameters. UPLC-ESI-MS/MS method was used for profiling the flavonoids in petals of ten samples. The results showed that the petal color of Lagerstroemia can be divided into three color groups,including red,violet and white,and a total of 158 flavonoids were detected. The petal color of two Heimia species was yellow,and a total of 138 flavonoids were detected. Compared with Heimia,there were 32 metabolites with low content in the petals of Lagerstroemia. Among them,the relative content of apigenin-4-O-rhamnoside,apigenin-O- glucoside-O-rhamnoside,luteolin,luteolin-7-O-rutinoside,kaempferol-3-O-glucoside-7-O-rhamnoside,kaempferol-3-O-robinobioside,kaempferol-3-O-rutinoside,kaempferol-3-O-glucoside and kaempferol-7- O-glucoside in the petals of Heimia were much higher than that of Lagerstroemia,which were speculated to be the mainly metabolites in the yellow petals of Heimia. In Lagerstroemia,the main flavonoids metabolites of the violet and red group are anthocyanins,and the flavones and flavonolss in the white petals were mainly luteolin and quercetin. The difference in petal color was caused by the difference of intermediate products or final products accumulation in the flavonoid metabolism pathway between Lagerstroemia and Heimia.

Key words: Lagerstroemia, Heimia, petal color, flavonoids, UPLC-ESI-MS/MS
