In this proof of concept study we demonstrate direct utilization of limonene containing waste product orange peel as starting material for a biocatalytic cascade reaction. The product of this cascade is chiral carvolactone, a promising building block for thermoplastic polymers. Four different concepts were applied to augment limonene availability based on either water extraction solely, additio...

Plants use volatile terpene compounds as odor cues for communicating with the environment. Fleshy fruits are particularly rich in volatiles that deter herbivores and attract seed dispersal agents. We have investigated how terpenes in citrus fruit peels affect the interaction between the plant, insects, and microorganisms. Because limonene represents up to 97% of the total volatiles in orange (C...

The epoxidation of limonene with hidrogen peroxide was studied over zeolite Tibeta (a large pore material) and heteropoly acids on carbono and alumina supported. PW11/C was catalyst the best tested. Introduction In the last years, the increase in environmental restrictions lead to the search for new oxydant systems to replace the traditionals in order to avoid the generation of polluting efflue...

Introduction: Diabetes mellitus (DM) is a multi-factorial condition associated with oxidative stress. Limonene, as plant-derived antioxidant, can be used for treating DM. Objectives: An investigation on antioxidant effects in diabetic rats exposed to D-limonene. Materials and Methods: Sixty male Wistar were categorized into six groups follows: control (healthy rats), (untreated sham glibenclami...

The aim of this work is to evaluate the activity of R(+) limonene of against Anisakidae larvae. Its effectiveness was tested in vitro. The results obtained showed a significant activity of the compound against Anisakis larvae, suggesting further investigation on its potential use in the industrial marinating process. In this regard, the use of R(+) limonene in seafood products could be interest...

In the present study, we provided synthesis of a series R-(+)- and S-(-)-limonene-based thiosemicarbazones containing different pentacyclic heterocyclic nucleus moiety focused in search novel antitumor antileishmanial agents. assay, derivative imidazole S-(-)-limonene 8 was most active compound, especially for U-251, UACC-62 K562 human tumor cell lines with GI50 ranging from 1.0 to <0.25 µg....

This study reports the isolation of microorganisms that are resistant to environment containing limonene, the most important residue in the citrus industry. For the isolation, samples collected from strategic places of a citrus processing plant (yellow water, entrance and exit of the bagasse tank, effluent and deteriorated fruits found in bins, machine straps, fruit washers and plant floor), so...

background & aim: dracocephalum genus belongs to the lamiaceae family which has eight species in iran. dracocephalum kotschyi boiss is an important medicinal and aromatic plant that use in pharmaceutical industry. in addition, this species is used in iranian traditional medicine. the aim of current study was to examine the various growth regulations and explants on direct organogenesis of d...
