Two secoiridoid glycosides, loniceracetalides A and B, were isolated in very small amounts, together with 10 known iridoid glycosides, from the flower buds of Lonicera japonica. The structures of loniceracetalides A and B were determined by spectroscopic analysis.
从忍冬的花蕾中分离出了两种裂环环烯醚萜苷类化合物，忍冬缩醛苷A和忍冬缩醛苷B，含量极少，同时还分离出了10种已知的环烯醚萜苷。通过光谱分析确定了忍冬缩醛苷A和忍冬缩醛苷B的结构。
