Two serotonin derivatives, N,N-dimethylserotonin 5-O-β-glucoside (1a) and N-methylserotonin 5-O-β-glucoside (1b) were isolated from immature seeds of Zanthoxylum piperitum. Their structures were determined by multi-step conversion reactions and spectroscopic analyses. Immature seeds of Z. piperitum contained extremely high levels of compounds 1a and 1b of approximately 0.29% and 0.15% (w/w), respectively.
从竹叶花椒的未成熟种子中分离得到两种5-羟色胺衍生物,N,N-二甲基-5-O-β-D-吡�苷(1a)和N-甲基-5-O-β-D-吡喃葡糖苷(1b)。通过多步转化反应和光谱分析确定了它们的结构。竹叶花椒的未成熟种子中1a和1b的含量极高,分别约为0.29%和0.15%(w/w)。
