Phytochemistry, 1989, 28(1):189-191.
Abietane quinones from rabdosia lophanthoides.[Reference: WebLink]

METHODS AND RESULTS:
The dried leaves of Rabdosia lophanthoides were found to contain six new diterpenoids having a royleanoneskeleton, lophanthoidin A, Lophanthoidin B, lophanthoidin C, lophanthoidin D, lophanthoidin E, lophanthoidin F, and the known compounds, enmein, β-sitosterol and stigmasterol.
CONCLUSIONS:
The structures of the new compounds were elucidated by spectroscopic methods.
