Sapium baccatum

A new skeletal alkaloid, bukittinggine (36), was isolated from Sapium baccatum (Euphorbiaceae). The structure, which is closely related to both methyl homo-secodaphniphyllate (11) and daphnilactone B, was determined by X-ray analysis of its hydrobromide [43]. The presence of bukittinggine indicates that Sapium baccatum may be closely related to the genus Daphniphyllum (Figure 18.5). 

The two most interesting compounds in this group to be published this year are baccatin (145), a novel nortriterpenoid peroxide from the bark of Sapium baccatum, and papyriogenin G (146), a j8-lactone from the leaves of Tetra-panax papyriferum. The structure of the latter was solved by X-ray analysis.
