Phytochemical investigation of the stems and leaves of Lonicera hypoglauca Miq. led to the isolation of one novel methoxylated flavone, acunminatin (7,2′,4′-trihydroxyl-5,5′- methoxyflavone) (1), and fourteen known compounds (2–15), including six flavonoids (mearnsetin 2, kaempferol 3, acacetin 4, 5,7,3′,4′-tetramethoxyflavone 5, tricin 6, and 5,7,3′,4′,5′-pentamethoxyflavone 7), two coumarins (umbelliferone 8 and scopoletin 9), two phenylpropanoids (trans-ferulic acid 10 and chlorogenic acid 11), two iridoid glycosides (loganin 12 and sweroside 13), and two triterpenoids (uvaol 14 and ursolic acid 15). The structures of the compounds were identified by spectroscopic analysis and by comparing their spectral data with those reported in the literature. Five of these compounds (1, 2, 4, 5, and 7) were isolated from the L. genus for the first time, and compounds 6–8 and 14–15 were isolated for the first time from L. hypoglauca. The chemotaxonomic significance of the isolated compounds in the L. genus and the Caprifoliaceae family are discussed herein.

Lonicera hypoglauca Miq茎和叶的植物化学研究。导致分离出一种新的甲氧基黄酮、acunminatin（7,2',4'-三羟基-5,5'-甲氧基黄酮）（1）和十四种已知化合物（2 – 15），包括六种类黄酮（mearnsetin 2，山奈酚3 , 金合欢素4 , 5,7,3',4'-四甲氧基黄酮5 , tricin 6 , 和 5,7,3',4',5'-五甲氧基黄酮7 ), 两种香豆素 (伞形酮8和东莨菪碱9 ),两种苯丙素（反式阿魏酸10和绿原酸）11）、两种环烯醚萜苷（马钱子苷12和 sweroside 13）和两种三萜类化合物（紫杉醇14和熊果酸15）。通过光谱分析和将它们的光谱数据与文献中报道的数据进行比较来鉴定化合物的结构。这些化合物（五个1，2，4，5，和7）从分离大号。首次属，和化合物6 - 8和14 - 15中分离得到的第一次从L. hypoglauca. L 中分离化合物的化学分类学意义。属和 Caprifoliaceae 科在本文中讨论。
