• General Description: Rabdophyllin G, also known as Rabdosin C, is a Spiro-seco-kaurene type diterpenoid structurally related to rabdosin B, as confirmed through chemical correlation and X-ray crystallography. Its identity was established by mild acidic hydrolysis of rabdosin B, yielding a compound identical to rabdophyllin G, and both compounds were further validated by forming the same triacetate derivative. This structural revision highlights its significance in clarifying the taxonomy of diterpenoids from *Rabdosia japonica*.

STRUCTURAL REVISION OF RABDOSIN B FROM RABDOSIA JAPONICA

10.1016/0031-9422(90)85141-2

The study focuses on the structural revision of rabdosin B, a compound isolated from the plant Rabdosia japonica. Initially, rabdosin B was thought to belong to the B-.seco-ent-kaurene type of compounds, but further investigation revealed it actually belongs to the Spiro-seco-kaurene type. The revision was made by chemically correlating rabdosin B with rabdophyllin G. Mild acidic hydrolysis of rabdosin B yielded a compound identical to rabdophyllin G, which had its structure confirmed by X-ray crystallography. Both rabdosin B and rabdophyllin G were acetylated to form the same triacetate. The study also suggests that the structure of isodonal, another compound isolated from the same plant family, may be incorrect. The chemicals involved include rabdosin B, rabdophyllin G, and their derivatives such as the triacetate and rabdosinate, each playing roles in confirming the revised structure through various chemical reactions and analyses.
