A NEW DITERPENOID FROM LEUCOTHOE GRAYANA MAX.
A new minor diterpenoid was isolated from the leaves of Leucothoe grayana Max., and its structure was characterized as a secograyanane derivative(1, 3(S), 6(R), 14(R), 16(R)-tetrahydroxy-5-oxo-5,10-seco-ent-kaur-1(10)-ene) by spectroscopic and chemical studies.
