RESUMO
The novel assingment of 13C and 1HNMR data for cadina-4,10(15)-dien-3-one obtained from Hyptis verticillata is presented. The study revealed that cadina-4,10(15)-dien-3-one possesses chemosterilant activities against the economically important cattle tick, Boophilus microplus, and toxic action against adult Cylas formicarius the most destructive pest of sweet potato (I pomoea sp.) (AU)

A procedure for detection and measurement of Hypoglycin A in biological material is described, based on reaction of the amino acid with 1-dimethylaminonaphthalene-5-sulphonyl chloride (Dansyl chloride). The desired flourescent derivative can be separated from others by paper chromatography and measured by flourimetry after elution. Less than 0.2 microgram of hypoglycin A is detectable on chromatograms (AU)
