The aim of this work is the production of Parthenin toxin (sesquiterpene lactone) free vermicompost from Parthenium hysterophorus L. Five different concentration of P. hysterophorus and cow dung mixtures were vermicomposted using Eudrilus eugeniae. Parthenium mediated vermicompost showed an increase in plant nutrition, but decrease in organic carbon and phenol contents when it was compared to initial feed mixtures. The 30-35% of organic carbon and 32-48% of phenol contents were reduced during vermicomposting, which was achieved after 45 days of earthworm's activity. FT-IR spectra revealed the absence of Parthenin (sesquiterpene lactone) and phenols in vermicompost which was obtained at high concentration of cow dung. Earthworm's biomass gain was in low level in high concentration of P. hysterophorus (without cow dung). The results indicated that Parthenin toxin and phenols can be eradicated via vermicomposting if P. hysterophorus is mixed with appropriate quantity of cow dung.
本工作旨在利用 Eudrilus eugeniae 从一枝黄花中生产不含蓖麻毒素（倍半萜内酯）的蚯蚓粪。使用不同浓度的一枝黄花和牛粪混合物进行蚯蚓堆肥。与初始饲料混合物相比，一枝黄花介导的蚯蚓堆肥显示出植物营养增加，但有机碳和酚含量减少。在 45 天的蚯蚓活动后，有机碳含量减少了 30-35%，酚含量减少了 32-48%。傅里叶变换红外（FT-IR）光谱显示，在高浓度牛粪的情况下，获得的蚯蚓粪中没有蓖麻毒素（倍半萜内酯）和酚类物质。在高浓度一枝黄花（无牛粪）的情况下，蚯蚓的生物量增长水平较低。结果表明，如果将适量的牛粪与一枝黄花混合，可以通过蚯蚓堆肥消除蓖麻毒素和酚类物质。
