In the course of screening for novel naturally occurring insecticides from Chinese crude drugs, a MeOH extract of Alpinia oxyphylla was found to give an insecticidal activity against larvae of Drosophila melanogaster Meigen. From the extract, an insecticidal compound was isolated by bioassay-guided fractionation and identified as yakuchinone A (1) by GC, GC/MS, 1H and 13C NMR spectroscopy.
在从中药材中筛选新型天然杀虫剂的过程中，发现益智甲醇提取物对黑腹果蝇幼虫具有杀虫活性。通过生物测定导向的分级分离从该提取物中分离出一种杀虫化合物，并通过气相色谱、气相色谱/质谱、1H和13C核磁共振光谱鉴定为氧化姜黄酮A（1）。
