title: Dichotenol-A, B and C: the C-16 oxidized seco-dolastanes from the marine brown alga Dictyota dichotoma (Huds.) Lamour.
abstract: Marine brown alga Dictyota dichotoma (Dictyotaceae) collected from the Karachi coast of the Arabian Sea has yielded three new C-16 oxidized seco-dolastanes (diterpenoids) named dichotenol-A, B and C. Their structures have been characterized with the aid of 2D-NMR spectroscopic techniques.
