The purpose of this study was to investigate the production of flavor compounds from olive mill waste by microbial fermentation of Rhizopus oryzae and Candida tropicalis. Olive mill waste fermentations were performed in shake and bioreactor cultures. Production of flavor compounds from olive mill waste was followed by Gas Chromatography-Mass spectrometry, Gas chromatography- olfactometry and Sp...

An epoxide hydrolase from Rhodococcus erythropolis DCL14 catalyzes the hydrolysis of limonene-1,2-epoxide to limonene-1,2-diol. The enzyme is induced when R. erythropolis is grown on monoterpenes, reflecting its role in the limonene degradation pathway of this microorganism. Limonene-1,2-epoxide hydrolase was purified to homogeneity. It is a monomeric cytoplasmic enzyme of 17 kDa, and its N-ter...

During our screening program for agrochemicals from Chinese medicinal herbs and wild plants, the essential oil of Carum carvi fruits was found to possess strong contact toxicity against Sitophilus zeamais and Tribolium castaneum adults, with LD₅₀ values of 3.07 and 3.29 μg/adult, respectively, and also showed strong fumigant toxicity against the two grain storage insects with LC₅₀ values of 3.3...

BACKGROUND Plants used for traditional medicine produce diverse and complex secondary metabolites exhibiting various medicinal properties. The medicinal plant Haplophyllum tuberculatum is used by native people against malaria and parasitic infections. METHODS In this study and in order to contribute for the search of new natural drugs for leishmaniasis, the essential oils of H. tuberculatum l...

The present study was designed to determine the effects of the essential oil of Laurusnobilis L. (Lauraceae) and its three main components on α-glucosidase and reactive oxygenspecies scavenging activity. The chemical composition of the essential oil from Laurus nobilisL. leaves was analyzed by GC/GC-MS and resulted in the identification of 29 compounds,representing 99.18% of the total oil. 1,8-...

Abstract Haplophyllum tuberculatum is a plant commonly used in folk medicine to treat several diseases including vomiting, nausea, infections, rheumatism, and gastric pains. In the current study, H. essential oils, hydrosols, pure compounds R-(+)-limonene, S-(−)-limonene, 1-octanol, as well their combinations R-(+)-limonene/1-octanol S-(−)-limonene/1-octanol, were screened for cytotoxicity on H...

Brazilian fish farming goes together with the emergence of numerous bacterial diseases, Aeromonas hydrophila being main pathogen. As a consequence, antimicrobials are excessively used. Considering that relatively stable and nonbiodegradable, medicinal plants their phytochemicals have been used as alternative treatments bacteriosis in farming. Limonene is monoterpene available two enantiomers: R...

Myoga is a fragrant plant which is the special product of Japan and is cultivated throughout Japan. According to our earlier investigation (unpublished data) of myoga cultivators in Japan, 8 of 35 cultivators experienced contact dermatitis in the harvest season. The purpose of this study was to assess the allergenicity of myoga and its major volatile components. The volatile components of myoga...

the present study was designed to determine the effects of the essential oil of laurusnobilis l. (lauraceae) and its three main components on α-glucosidase and reactive oxygenspecies scavenging activity. the chemical composition of the essential oil from laurus nobilisl. leaves was analyzed by gc/gc-ms and resulted in the identification of 29 compounds,representing 99.18% of the total oil. 1,8-...
