Abstract
The structure of a new labdane diterpene, limonidilactone, from the le aves of Vitex limonifolia Wall. (Verbenaceae) has been established by spectroscopic methods and a single-crystal X-ray structure determinati on. Crystals are orthorhombic, P2(1)2(1)2(1), a 19.373(10), b 10.871(7 ), c 8.207(3) Angstrom, Z 4. Diffractometer data were refined by full- matrix least-squares techniques to a residual of 0.043 for 1436 indepe ndent 'observed' reflections.
