Abstract

L. contains high amounts of flavonoids and phenolic acids. However, there is limited information on the composition of these compounds in different parts of the plant. The present study analyzed the secondary metabolite profiles of the stem, leaf, flower, and seed of L.cv. Mengzao (LIM) using a widely targeted metabolomic approach. A total of 576 secondary metabolites were identified, including 218, 267, 232, 286, 302, and 308 differentially accumulated metabolites (DAMs) in the stem_vs_leaf, stem_vs_flower, stem_vs_seed, leaf_vs_flower, leaf_vs_seed, and flower_vs_seed comparisons. In particular, considerable differences were detected in the flavonoids and phenolic acids, five flavonoids, five phenolic acids, one triterpenoid and one alkaloid being differentially accumulated in the four parts. Compared to the stem and flower, the leaf and seed had higher total flavonoid content and total phenolic content. Thses findings provide comprehensive insights into utilizing different parts of LIM in developing functional food products.

摘要

L.含有大量黄酮类化合物和酚酸。然而，关于这些化合物在该植物不同部位的组成信息有限。本研究采用广泛靶向代谢组学方法分析了L.cv.蒙早（LIM）的茎、叶、花和种子的次生代谢产物谱。共鉴定出576种次生代谢产物，包括在茎与叶、茎与花、茎与种子、叶与花、叶与种子以及花与种子比较中分别有218、267、232、286、302和308种差异积累代谢物（DAMs）。特别是，在黄酮类化合物和酚酸方面检测到相当大的差异，四种部位中有五种黄酮类化合物、五种酚酸、一种三萜类化合物和一种生物碱差异积累。与茎和花相比，叶和种子的总黄酮含量和总酚含量更高。这些发现为利用LIM的不同部位开发功能性食品提供了全面的见解。
