title: 13-Deoxyitol A, a new insecticidal isoryanodane diterpene from the seeds of Itoa orientalis.
abstract: A new isoryanodane diterpene, 13-deoxyitol A (1), together with a known isoryanodane diterpene, itol A (2), was isolated from the methanol extract of the seeds of Itoa orientalis. Its structure was determined by spectroscopic means. Compounds 1 and 2 showed antifeedant and contact toxic activities against various insect pests.
