kadsura oblongifolia/adenosine

A phytochemical investigation of the stems of Kadsura interior has led to an isolation of four new lignans, named kadsutherin E⁻H (1⁻4), together with two known lignans (5⁻6). The structures of the four new compounds were established on the basis of comprehensive spectroscopic analyses. Compounds

From the stems of Kadsura heteroclita, two new lignans named heteroclitins F and G were isolated and their structures were determined by various spectroscopic means including an X-ray diffraction method. Dibenzocyclooctadiene type lignans and related compounds isolated from the stems of K.
