Showing papers on "Terpene published in 1982"
TL;DR: Results of toxicity tests with several congeners of R -(+)-pulegone strongly implicated the α-isopropylidene ketone group as the structural unit required for eliciting hepatotoxicity, although the configurational orientation of the methyl group can modulate the hepatotoxic response.

TL;DR: In this paper, samples were obtained of the volatile essential oils of the two types of curry leaf, Murraya koenigii and Pandanus latifolius, which contained mainly terpenes and sesquiterpene hydrocarbons.

TL;DR: This article investigated the volatile components in botrytized grape must and transformation of terpenoids in terpene-supplemented grape must by Botrytis cinerea.
Abstract: Experiments were done to investigate the volatile components in botrytized grape must and transformation of terpenoids in terpene-supplemented grape must by Botrytis cinerea Twenty-eight compounds were identified in the volatile concentrate of botrytized must with a combined gas chromatograph-mass spectrometer No terpenoids were detected in the concentrate Linalool or terpinen-4-ol decreased a lot when Botrytis cinerea was cultured in the must with these terpenes for 15 days In linalool-supplemented botrytized must 9 identified and 3 unidentified terpenes were found, while only geranial was detected in terpinen-4-ol-supplemented botrytized must Botrytis cinerea did not produce terpenoid in grape must without terpenes, but transformed linalool added to grape must into some other monoterpenes

14 Oct 1982TL;DR: In this paper, a process for the conversion of terpenes to limonene which comprises contacting at least one terpene, selected from the group comprised of mono- and bi-cyclic unsaturated hydrocarbons having the formula C10 H16 with an alkali metal sulfide catalyst on a support at a temperature of 300° to 450° C.
Abstract: There is disclosed a process for the conversion of terpenes to limonene which comprises contacting at least one terpene, selected from the group comprised of mono- and bi-cyclic unsaturated hydrocarbons having the formula C10 H16 with an alkali metal sulfide catalyst on a support at a temperature of 300° to 450° C.

TL;DR: In this article, a stereoselective total synthesis of (±)-cubitene, a diterpene isolated from termite soldiers, and its stereisomer has been achieved utilizing the anion-induced intramolecular cyclization.

TL;DR: Linalyl pyrophosphate is a sterically plausible precursor of cyclic hydrocarbons, but the present data support only its role as an alternative substrate and not as an obligatory free intermediate in terpene biosynthesis.

TL;DR: In this article, a new terpene glucoside, Loliolide-β-d-glucopyranoside from Flue-cured Tobacco, was isolated.
