Abstract Phytochemical research on the flower buds of Lonicera japonica Thunb. led to the isolation of 15 compounds, including nine terpenoids (1–9), three phenylpropanoid glycosides (10–12), two alkyl glycosides (13–14) and an alkaloid (15). The structures of these compounds were determined by NMR spectroscopy and comparison with data from previous literatures. Among them, eleven compounds (2–5, 8, 10 and 11–15) were reported from the genus Lonicera for the first time and compounds 3, 4, 5, 10 and 11–15 were firstly reported from the family Caprifoliaceae. Network analysis was carried out to explore the chemotaxonomic significance of these compounds for L. japonica in this study.

忍冬的植物化学和基于网络的化学分类学研究

摘要 忍冬花芽的植物化学研究。导致分离出 15 种化合物，包括九种萜类化合物 (1-9)、三种苯丙烷苷 (10-12)、两种烷基糖苷 (13-14) 和一种生物碱 (15)。这些化合物的结构是通过核磁共振光谱确定的，并与以前文献中的数据进行比较。其中，忍冬属首次报道了11个化合物（2-5、8、10和11-15），忍冬科首次报道了化合物3、4、5、10和11-15。进行网络分析以探讨这些化合物在本研究中对 L. japonica 的化学分类学意义。
