Terpenoids from Elsholtzia Species; II1. Constituents of Essential Oil from a New Chemotype of Elsholtzia cristata

Planta Med. 1987 Jun;53(3):268-71. doi: 10.1055/s-2006-962701.

Abstract

Capillary GC, GC-MS, (1)H-, and (13)C-NMR spectroscopy revealed that the essential oil of ELSHOLTZIA CRISTATA Willd. growing in the Kumaun region contains 88% dehydroelsholtzia ketone along with some minor acylfuran derivatives. This species with respect to its oil composition is unlike that which grows in Japan and Kashmir, and contains elsholtzia ketone as the main constituent.
