title: [Chemical constituents of Cuscuta austrolis R.Br].
abstract: Australiside A(1), a new diterpenoid glucoside, was isolated together with thymidine(2), caffeic acid(3), p-coumaric acid(4) and caffeic-beta-D-glucoside(5) from Cuscuta australis. Based on spectral analysis and physico-chemical properties the structures of the above-cited five compounds were identified. The structure of compound 1 was deduced as 4-oic acid-7-oxo-kaurene-6 alpha-O-beta-D-glucoside. Compounds 2, 3, 4 and 5 were obtained from Cuscuta for the first time.
