Four unprecedented diarylheptanoids-calyxin H (1) and epicalyxin H (2), possessing a diarylheptanoid unit and a chalcone moiety, and blepharocalyxins A (3) and B (4), possessing two diarylheptanoid units and a chalcone moiety-were isolated from the seeds of Alpiniablepharocalyx. The structures of 1-4, including absolute stereochemistry, were elucidated by spectroscopic means and after a consideration of their biogenesis.
从毛萼山姜种子中分离出四种前所未有的二芳基庚烷类化合物——具有二芳基庚烷单元和查耳酮部分的卡里辛H（1）和表卡里辛H（2），以及具有两个二芳基庚烷单元和查耳酮部分的毛萼山姜素A（3）和B（4）。通过光谱手段并考虑其生源合成对1-4的结构（包括绝对立体化学）进行了阐明。
