✦ Synopsis

RECKNTLY, Btlchi, Greuter and Tokoroyamal published their results about structure of calarene (characterised mainly by @OB +58') isolated from the so called Chinese Spikenard oil (from Nardostachys jatamanis /Koxb/DC.) and allotted structure I for it. The hydrocarbon calarene had been isolated also from sweet-flag oil in this Laboratory' nearly ten years ago. Bflchi and coworkers 1 elucidated also stereochemistry of aristolone (II), a sesquiterpenic ketone, the constitution of which had been ascertained by Furukawa et a1.3 last year.

We studied independently the structure of calarene, characterised in our case by [gi" + 23.6', which had been newly isolated from the sweet-flag oil (Acorus oalamus L.) using the already reported procedure2; further, me investigated structure ofp-gurjunene (III) obtained from gurjunbalsam
