Methanolic extracts prepared from dried leaves of Jasminum officinale f. var. grandiflorum (L.) Kob. (Spanish jasmine) inhibited seed germination and stunted both root and shoot length of the weeds Echinochloa crus-galli (L.) Beauv. and Phaseolus lathyroides L. The main active compound was isolated and determined by spectral data as a secoiridoid glucoside named oleuropein. In addition, a decrease in allelopathic efficacy appeared as the decomposition periods increased. The mitotic index in treated onion root tips decreased with increasing concentrations of the extracts and longer periods of treatment. Likewise, the mitotic phase index was altered in onion incubated with crude extract. Furthermore, crude extract produced mitotic abnormalities resulting from its action on chromatin organization and mitotic spindle.
从 Jasminum officinale f. var. grandiflorum（L.）Kob.（西班牙茉莉）干叶制备的甲醇提取物抑制了杂草稗草（L.）Beauv.和菜豆（L.）的种子萌发，并使根和茎的长度变短。主要活性化合物通过光谱数据分离并确定为一种名为橄榄苦苷的裂环环烯醚萜糖苷。此外，随着分解时间的增加，化感效应会降低。用提取物处理洋葱根尖的有丝分裂指数随着提取物浓度的增加和处理时间的延长而降低。同样，用粗提取物孵育的洋葱的有丝分裂相指数也发生了改变。此外，粗提取物通过作用于染色质组织和有丝分裂纺锤体产生有丝分裂异常。
