Abstract

Methanol extracts of Kaempferia rotunda L. rhizomes yielded seven compounds including six polyoxygenated cyclohexane derivatives identified as (−)-6-acetylzeylenol (1), four acylated derivatives of 1-benzoyloxymethyl-1,6-epoxycyclohexan-2,3,4,5-tetrol (3–6), a Diels–Alder adduct of 3-benzoyl-1-benzoyloxymethylcyclohexa-4,6-dien-2,3-diol (7), and a triacylated derivative of salicin (9). The cyclohexane diepoxide, crotepoxide (8), was also obtained. Spectroscopic methods were used for structure determination. The methanol extract of the rhizomes of K. rotunda and (−)-2-acetyl-4-benzoyl-1-benzoyloxymethyl-1,6-epoxycyclohexan-2,3,4,5-tetrol (2-acetylrotepoxide B; 6), had antifeedant activity against larvae of Spodoptera littoralis. (−)-Zeylenol (2) also showed antifeedant activity, whereas (−)-6-acetylzeylenol (1) was inactive.
