中间连翘的叶和茎中含有4种主要的木脂素及其O-糖苷。这些化合物被鉴定为二苄基丁内酯衍生物（. sbd.）。牛蒡苷元，牛蒡苷[（. sbd.）-牛蒡子苷元4“-O-葡萄糖苷]，（. sbd.）- matairesinol和（. sbd.）- matairesinol 4“-O-葡糖苷，以及呋喃木脂素（+）-连翘苷元、连翘苷[（+）-连翘苷元4-O-葡糖苷]、（+）-表半夏醇和（+）-表半夏醇4”-O-葡糖苷。木脂素含量因组织类型和季节而异。木脂素的全光谱数据。1H NOE差谱记录phillygenin和epipinerinol有必要扭转早期的化学位移分配轴向和赤道质子上的C-9呋喃木脂素具有一个轴向和一个赤道芳基（epi系列）。
Leaf and stem material of Forsythia intermedia contains four main lignans and their O-glucosides. These were identified as the dibenzylbutyrolactone derivatives (.sbd.)-arctigenin, arctiin [(.sbd.)-arctigenin 4''-O-glucoside], (.sbd.)-matairesinol and (.sbd.)-matairesinol 4''-O-glucoside, together with the furofuran lignans (+)-phillygenin, phillyrin [(+)-phillygenin 4-O-glucoside], (+)-epipinoresinol and (+)-epipinoresinol 4''-O-glucoside. The lignan contents varied according to tissue type and season. Full spectral data for the lignans are presented. The 1H NOE difference spectra recorded for phillygenin and epipinoresinol necessitate the reversal of earlier chemical shift assignments for axial and equatorial protons on C-9 of furofuran lignans having one axial and one equatorial aryl group (the epi series).
