Biotransformation of cadinane sesquiterpenes by Beauveria bassiana ATCC 7159
摘要:
Incubation of cadina-4.10(15)-dien-3-one with Beauveria bassiana ATCC 7159 has resulted in the production of nine novel sesquiterpenes. These metabolites were identified as (4S)-cadin-10(15)-en-3-one, (4S)-3 alpha-hydroxycadin-10(15)-ene, (4R)-3 alpha-hydloxycadin-10(15)-ene, (4S)-3 beta-hydroxycadin-10(15)-ene, (4S)-3 beta-hydroxycadina-10(15),12(14)-diene, (4S)-13-hydroxycadin-10(15)-en-3-one, (4S)-12-hydroxycadin-10(15)-en-3-one, (4R)-3 beta,14-dihydroxycadin-10(15)-ene and 3 alpha-hydroxycadina-4,10(15)diene. The allylic alcohol 3 alpha-hydroxycadina-4 10(15)-diene was also biotransformed to afford cadina-4,10(15)-dien-3-one, (4S)-cadin-10(15)-en-3-one and (4S)-12-hpdroxycadin-10(15)-en-3-one. The insecticidal potential and phytotoxicity of the isolated metabolites have been evaluated, (C) 2000 Elsevier Science Ltd. All rights reserved.
Biotransformation of cadina-4,10(15)-dien-3-one and 3α-hydroxycadina-4,10(15)-diene by Curvularia lunata ATCC 12017
摘要:
Cadina-4,10(15)-dien-3-one (1) was metabolised by Curvularia lunata ATCC 12017 in two different growth media to give three metabolites, one of which, 12-hydroxycadina-4,10(15)-dien-3-one (4), was new. Incubation of 3a-hydroxycadina-4,10(15)-diene (2) with the fungus produced three new analogues, namely, (4S)-1alpha,3alpha-dihydroxycadin-10(15)-ene (5), 3alpha,14-dihydroxycadina-4,10(15)diene (6) and 3alpha, 12-dihydroxycadina-4,10(15)-diene (7).

Squamulosone (aromadendr-1(10)-en-9-one). isolated in large quantity from the plant Hyptis verticillata Jacq. (Labiatae), was incubated with the fungus Curvularia lunata ATCC 12017 in two different growth media. Six metabolites were isolated from each medium, with five of the products being common to both fermentations. All seven metabolites are novel. The insecticidal activity of these aromadendranes was evaluated against the sweet potato weevil Cylas formicarius elegantulus. (C) 2001 Elsevier Science Ltd. All rights reserved.

The present invention relates to the development of a novel, morphologically and genetically distinct khusinol rich essential oil producing clone of vetiver [
Vetiveria zizaniodes
(L.) Nash. syn.
Chrysopogon zizanioides
(L.) Roberty; family Poacaeae} named ‘CIMAP-Khusinolika’. The plant of this clone is characterized by spreading type clump canopy in the initial stage, white feathery stigma and capable of producing >1% (v/w) essential oil containing 45-50% Khusinol (v/v) obtained after hydro-distillation from fresh roots harvested from 6 month old plantations. This clone has unique ISSR profiles that serve as DNA-fingerprints. The clone was obtained through recurrent selection in polycrossed population generated from the bulk of wild collection, and can be propagated through vegetative slips (3 to 6 month old stem with few roots) for commercial plantation as a short duration crop.
