Abstract

Natural volatile organic compounds (VOCs) obtained from five Rubiaceae plants native to south China, namely Damnacanthus indicus, Hamelia patens, Exallage chrysotricha, Psychotria serpens, and Spermacoce pusilla, were isolated and characterized in this study. The analysis revealed that each plant contained 71, 57, 80, 73, and 70 volatile organic chemical compounds, respectively. The main VOCs shared by five plants was palmitate (10.20%–36.26%). Methyl salicylate, caryophyllene oxide, tetradecanoic acid, 6,10,14-trimethyl-2-pentadecanone, pentadecanoic acid, pentacosane, pentadecanal, nonanal, hexadecanoic acid methyl ester, phytol, linalool, and (E)-β-ionone were shared by at least 4 Rubiaceae plants in this study. Besides, each of the five plants has its main components as follows: 12.81% ethyl linoleate and 6.13% (E)-13-octadecenoic acid for D. indicus; 35.17% methyl salicylate for H. patens; 9.50% (Z, Z)-9,12-octadecadienoic acid and 7.56% endo-borneol for E. chrysotricha; 13.93% methyl salicylate for P. serpens; 6.19% humulene and 6.08% humulene oxide II for S. pusilla. This research provides insights into the phytochemical diversity and classification of Rubiaceae plants, laying a solid foundation for future natural product development in the Rubiaceae family.

五种茜草科植物的挥发性有机成分：洞察植物化学多样性

本研究从五种原产于中国南方的茜草科植物中分离并表征了天然挥发性有机化合物（VOCs），这五种植物分别是茜草（Damnacanthus indicus）、茜草（Hamelia patens）、茜草（Exallage chrysotricha）、茜草（Psychotria serpens）和茜草（Spermacoce pusilla）。分析表明，每种植物分别含有 71、57、80、73 和 70 种挥发性有机化学化合物。五种植物共有的主要挥发性有机化合物是棕榈酸酯（10.20%-36.26%）。本研究中至少有 4 种茜草科植物共享水杨酸甲酯、氧化香叶醇、十四酸、6,10,14-三甲基-2-十五烷酮、十五烷酸、十五烷、十五醛、壬醛、十六酸甲酯、植物醇、芳樟醇和 (E)-β-ionone 等挥发性有机化合物。此外，五种植物的主要成分如下：D. indicus 的亚油酸乙酯含量为 12.81%，(E)-13-十八碳烯酸含量为 6.13%；H. patens 的水杨酸甲酯含量为 35.17%；(Z, Z)-9,12-十八碳烯酸含量为 9.50%，内龙脑含量为 7.56%。E. chrysotricha 含 9.50% (Z, Z) -9,12-octadecadienoic acid 和 7.56% endo-borneol; P. serpens 含 13.93% methyl salicylate; S. pusilla 含 6.19% humulene 和 6.08% humulene oxide II。这项研究有助于深入了解茜草科植物的植物化学多样性和分类，为茜草科植物未来的天然产品开发奠定了坚实的基础。

期刊介绍： Biochemical Systematics and Ecology is devoted to the publication of original papers and reviews, both submitted and invited, in two subject areas: I) the application of biochemistry to problems relating to systematic biology of organisms (biochemical systematics); II) the role of biochemistry in interactions between organisms or between an organism and its environment (biochemical ecology). In the Biochemical Systematics subject area, comparative studies of the distribution of (secondary) metabolites within a wider taxon (e.g. genus or family) are welcome. Comparative studies, encompassing multiple accessions of each of the taxa within their distribution are particularly encouraged. Welcome are also studies combining classical chemosystematic studies (such as comparative HPLC-MS or GC-MS investigations) with (macro-) molecular phylogenetic studies. Studies that involve the comparative use of compounds to help differentiate among species such as adulterants or substitutes that illustrate the applied use of chemosystematics are welcome. In contrast, studies solely employing macromolecular phylogenetic techniques (gene sequences, RAPD studies etc.) will be considered out of scope. Discouraged are manuscripts that report known or new compounds from a single source taxon without addressing a systematic hypothesis. Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
