Abstract
A new method, utilizing image analysis on TLC, was developed for the d etermination of zygacine, the neurotoxic steroidal alkaloid in death c amas (Zigadenus venenosus). The quantitative detection level of zygaci ne on TLC was 1 mu g. Diurnal changes in zygacine levels were not evid ent, nor were there differences in zygacine levels in death camas grow ing at high- or low-elevation habitats. The image analysis method was also applied to the determination of vanillylveracevine in Zigadenus e legans.
