Abstract

The aroma characteristics of flowers and leaves from G. jasminoides were comprehensively explored using HS-GC-MS technology, coupled to relative odour activity value (rOAV) determination and PCA analysis. A total of 116 volatiles were identified in G. jasminoides, with 71 common volatiles detected in both the leaves (GJ-L) and flowers (GJ-F). Alkenes were found to be the most abundant volatiles in both samples, both in terms of quantity and relative abundance. Notably, 2,3-butanedione (rOAV = 100) was identified as the key contributor to buttery aroma in GJ-F, while 3-methylbutanal (rOAV = 100) was the principal contributor to fruity odour in GJ-L. PCA further revealed significant differences in the aroma characteristics between GJ-F and GJ-L. This study enhances our understanding of the volatile compositions and odour characteristics of different parts (flowers and leaves) of G. jasminoides, providing a theoretical basis for the development and utilisation of products derived from G. jasminoides.

用HS-gC-MS研究栀子花和叶的香气特征。

采用HS-GC-MS技术，结合相对气味活性值（rOAV）测定和PCA分析，对茉莉花和叶的香气特征进行了全面研究。共鉴定出116种挥发物，其中71种挥发物在叶（GJ-L）和花（GJ-F）中均有检出。烯烃被发现是两个样品中最丰富的挥发物，无论是在数量上还是相对丰度上。值得注意的是，2,3-丁二酮（rOAV = 100）被确定为GJ-F中黄油气味的主要贡献者，而3-甲基丁醛（rOAV = 100）是GJ-L中水果气味的主要贡献者。PCA进一步揭示了GJ-F和GJ-L在香气特性上的显著差异。本研究提高了我们对茉莉花不同部位（花和叶）挥发性成分和气味特征的认识，为茉莉花衍生产品的开发利用提供了理论依据。

期刊介绍： The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds. The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal. Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section. All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
