Monoterpenes of Teucrium marum

Australian Journal of Chemistry, 1976
Four cyclopentanoid monoterpenes were isolated from Teucrium marum; they are the two [(A) and (B)] C2-epimers of a-(2-formyl-3-methylcyclopentyl)acrylaldehyde and two new [(C) and (D)] isomeric unsaturated lactones. Structures were established by spectral (u.v., i.r., N.M.R., m.s.) evidence and chemical transformations.

Monoterpene biotransformation by Colletotrichum species

Biotechnology Letters, 2017
To investigate the biocatalytic potential of Colletotrichum acutatum and Colletotrichum nymphaeae for monoterpene biotransformation.C. acutatum and C. nymphaeae used limonene, α-pinene, β-pinene, farnesene, citronellol, linalool, geraniol, perillyl alcohol, and carveol as sole carbon and energy sources. Both species biotransformed limonene and linalool,

Monoterpenes in grape juice and wines

Journal of Chromatography A, 2000
The importance of monoterpenes on varietal flavour of wines has been reviewed. These compounds were mainly found linked to sugar moieties in the grape juice and wines, showing no olfactive characteristics. In this way, mechanisms to liberate terpenes were studied, making a comparative study between acidic and enzymic hydrolysis of terpene glycosides ...

Molecular Engineering of Monoterpene Production

1998
The terpenoids (often referred to as isoprenoids) constitute the largest group of natural products, with more than 22, 000 individual structures now known (1). They are all derived from the sequential addition of branched, five-carbon isopentenoid (isoprenoid) units, and range in size from isoprene (C5H8) to natural rubber (molecular weight greater ...

Monoterpene hydrocarbons in the nighttime troposphere

Environmental Science & Technology, 1985
Monoterpene hydrocarbons were measured during the night at a rural site in the Rocky Mountains. The compounds positively identified and quantified were ..cap alpha..-pinene, camphene, ..beta..-pinene, ..delta../sup 3/-carene, and d-limonene. The average sum of the mixing ratios of the five compounds measured during the nighttime between July and Oct ...

Just how insoluble are monoterpenes?

Journal of Chemical Ecology, 1993
Prior generalizations about the ecological roles of monoterpenes may be misleading if based on the presumed insolubility of monoterpenes in water. We determined the aqueous solubility of 31 biologically active monoterpenes by gas chromatography. While hydrocarbons were of low solubility (< 35 ppm), oxygenated monoterpenes exhibited solubilities one or ...

Biosynthesis of Monoterpenes in Rose Flowers

Nature, 1970
ALTHOUGH mevalonic acid (MVA) is generally assumed to be an obligatory precursor of terpenes in higher plants, incorporation of 2-14C-MVA into the principal monoterpenes of numerous species is almost invariably less than 1 per cent (ref. 1). Monoterpene biosynthesis is nevertheless assumed to occur via conversion of MVA into isopentenyl pyrophosphate ...

Monoterpene indole alkaloids and monoterpene diglycosides from the roots of Triosteum pinnatifidum

Phytochemistry Letters, 2014
Five monoterpene indole alkaloids (vincosamide-6′-O-β-d-glucopyranoside (1), vincosamide (2), strictosamide (3), strictosidine (4), and 5(S)-5-carboxystrictosidine (5)), and two monoterpene diglycosides (urceolide (6) and 4(S)-4-hydroxyurceolide (7)) were isolated from the roots of Triosteum pinnatifidum.

Opportunities in microbial biotransformation of monoterpenes

1997
Monoterpenes are important flavour and fragrance compounds. The biotransformation of monoter penes has been studied quite extensively during the past 30 years. Specific problems have been encountered during these studies which have prevented the commercialization of monoterpene biotransformation processes.
