Detected volatile constituents in studied species were constituted mainly by sesquiterpene, as well as diterpene compounds. All so-established compositions cannot successfully index some of them to known chemotypes but afforded the discovery of new chemotypes such as cuparane/fusicoccane. The major component of B. francana was isolated and characterized as a new zierane-type sesquiterpene called ziera-12(13),10(14)-dien-5-ol (23). In addition, qualitative intraspecies variations of chemical composition were very important particularly for B. francana which possessed three clearly defined different compositions. We report here also the first phytochemical investigation of Acromastigum species. Moreover, crude diethyl ether extract of B. vitatta afforded a new bis(bibenzyl) called vittatin (51), for which a putative biosynthesis was suggested. specialized PLANTE UTILE PHYTOCHIMIE COMPOSITION CHIMIQUE BIOSYNTHESE CHIMIOTAXONOMIE NOUVELLE CALEDONIE 076BOTA11 23 6 art. no 1353 [27 ] 2018 1420-3049 https://www.documentation.ird.fr/hor/fdi:010075999 10.3390/molecules23061353 1420-3049 [F B010075999] https://www.documentation.ird.fr/hor/fdi:010075999 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers19-06/010075999.pdf IRD - Base Horizon / Pleins textes 2019-06-06 2023-07-11 fdi:010075999 fre
