The present work performed a systematical analysis of the aqueous extract of newborn black widow spiderlings.The extract was shown to contain 69.42％ of proteins varying in MWs and pls.Abdominal injection of the extract into mice and cockroaches caused obvious poisoning symptoms as well as death,with LD50 being 5.30 mg/kg in mice and 16.74 μg/g in P americana.
