Limonoids are distinctive secondary metabolites of the Citrus essential oils, derived from limonene
compound and showed large number of pharmacological and biological activities [15-16]
In contrast, [alpha]-pinene, [beta]-myrcene, limonene
, bornyl acetate, geranyl acetate, and [beta]-caryophyllene were inactive against Y.
Co-encapsulation of fish oil with phytosterol esters and limonene
by milk proteins.
The use of the silk to encapsulate limonene
provides a fully biodegradable, biocompatible encapsulation system which demonstrates the potential for limonene
stabilization at elevated temperatures.
a-pinene and AY-pinene were ordered from product supplier of Alfa Aesar company in Beijing China.
The substances present in the reactant system include limonene
([C.sup.10][H.sup.16]) and hydrogen peroxide ([H.sup.2][O.sup.2]) as reactant species, acetonitrile (C[H.sup.3]CN) as solvent and water ([H.sup.2]O) and limonene
epoxide ([C.sup.10][H.sup.16]O) as products (Reaction R1) (Barrera et al., 2010).
For reference standards we used [alpha]-pinene, 99 percent pure, 0.85 g [mL.sup.-1] density (Acros Organic, Somerville, New Jersey); [beta]-pinene, 97 percent pure, 0.86 g [mL.sup.-1] density (Alpha Aesar, Ward Hill, Massachusetts); terpineol, 90 percent pure, with a density of 0.93 g [mL.sup.-1] (Spectrum Chemical Manufacturing Corp., New Brunswick, New Jersey); limonene
, 97 percent pure, 0.842 g [mL.sup.-1]; and (-)-frarcs-caryophyllene, 98.5 percent pure, 0.902 g [mL.sup.-1] (Sigma Aldrich, Milwaukee, Wisconsin).
The strains that showed the greatest resistance to d-limonene and capable of using limonene
as sole carbon source were identified by 16s rRNA gene sequencing technique.
The results revealed a unique constituent in major proportion (>90%) and five principal compounds: limonene
, [beta]-ocymene, [delta]-3-carene, [alpha]-pinene, and myrcene.
Shampoos, soaps, perfumes, domestic cleaners, sunscreens, and massage creams are among the household products likely to contain limonene
The aim of the study was to evaluate antibacterial activity of Caraway essential oil obtained from fruit originated from different genotypes and investigate the correlation between this activity and essential oil content and its main components (carvone and limonene
(2) mixture of [alpha]-pinene (24 mg), [beta]-pinene (57 mg), myrcene (14 mg), and limonene
(6 mg) in 100 mL hexane resembling the secretion of Z.
