摘要：

Coleonol-B a diterpenoid isolated from the roots of the Indian plant Coleus forskohlii crystallizes in the orthorhombic system, space group P2(1)2(1)2(1) with a = 29.085(5), b = 11.603(2), c = 6.341(1) angstrom and four molecules in the unit cell. As in Coleonol, the substituents at the 6- and 7-positions are in the beta-configuration. 2133 reflections were used, 398 parameters were refined. Final R-values were R(w) = 0.057 and R = 0.045.
