and their structures elucidated by NMR spectroscopy. Some hydroxylated menthols showed plant growth inhibitory and strong mosquito repellent activity. Among the hydroxylated cineoles, microbial and animal metabolites of cineoles were included. From ent-kauranes, a plant growth inhibitory diterpene alcohol, (−)-16α-hydroxy kaurane was obtained along with 16α-kauran-13α-ol.
