在非洲，野芝麻被广泛用作香料。两个未描述的paradol相关化合物，（S）−9-羟基-[6]-paradol（1）和（9 S）− 3，9-二羟基二氢-[6]-paradol（2）以及八个已报道的成分（3-10）从A的甲醇提取物中分离和表征。我的瓜子。通过NMR和质谱数据分析实现了这些代谢物的结构解析。用改进的Mosher方法确定了未描述化合物（1和2）的绝对构型。
Aframomum meleguetaseeds are widely used as a spice in Africa. Two undescribed paradol-related compounds, (S)−9-hydroxy-[6]-paradol (1) and (9S)−3,9-dihydroxydihydro-[6]-paradol (2) together with eight reported constituents (3-10) were isolated and characterised from the methanol extract ofA. meleguetaseeds. Structure elucidation of these metabolites was achieved by means of NMR and mass spectroscopic data analyses. The absolute configuration of undescribed compounds (1and2) was determined using the modified Mosher’s method.
