The absolute configuration of (+)-2,7(14),10-bisabolatrien-1-ol-4-one, a peculiar sesquiterpenol in the Japanese cedar, Cryptomeria japonica, was determined as (1S,6R)-2,7(14),10-bisabolatrien-1-ol-4-one by comparing the specific rotation values of cryptomeriones respectively converted from (+)-2,7(14),10-bisabolatrien-1-ol-4-one and synthesized from (R)-(-)-carvone.

A new chiral diketonate ligand based on carvone binds early lanthanides. The Eu complex displays high circularly polarized (g(lum) = 0.82) red luminescence under near-UV excitation in the solid state. This is the first report on such CPL activity in the solid state with a rigorous protocol to exclude artifacts. Paramagnetic NMR spectroscopy revealed the nature and structure of the active species.

In the course of our continuing work on transformation of monoterpenes by microorganisms, the biotransformation of (+)- and (-)-carvone was carried out. The metabolites formed during microbial transformations were screened using a simple, rapid and efficient technique: Headspace-solid phase microextraction (SPME)/GC-MS. The results as well as the application of this technique are described.

Background: Diabetes mellitus is a metabolic disorder causing dysfunctional regulation of carbohydrate metabolism and contributing to multiple serious health challenges worldwide. Aims: This research explores the effect caraway hydroalcoholic extract (S)-(+)-carvone on transcription genes coding for key glycolytic enzymes in liver diabetic rat treated with streptozotocin (STZ). Methods: In this...

     To evaluate the effects of hydrogel polymer levels (0, 10, 20, 30 g m-2) and NO3:NH4 ratios (0: 100, 25: 75, 50: 50, 75: 25, and 100: 0) on dill seed yield and its essential oil constituents, an experiment was conducted in October 2012 in the experimental field of Islamic Azad University, Jiroft, Iran. Results showed that using 30 g m-2 hydrogel polymer with 75NO3-: 25 NH4+ ratio produced ...

Chemical composition, antioxidant and anti-Vibrio spp. activities of the essential oil isolated from the aerial parts of Mentha spicata L. (spearmint) are investigated in the present study. The effect of the essential oil on Vibrio spp. biofilm inhibition and eradication was tested using the XTT assay. A total of 63 chemical constituents were identified in spearmint oil using GC/MS, constitutin...

this study was conducted to assess the effects of irrigation and plant growth promoting bactera on seed yield and qualitative characteristics of black cumin (nigella sativa l.) at the experimental station of the research institute of forest and rangeland, damavan region, iran. a split-plot experimental design, based on randomized complete block design (rcbd) with three replications, was used. i...
