Lactarius vellereus

New sesquiterpenes of the lactarane (occasionally named also vellerane) group (Table 10) have been isolated by Swedish authors during their pioneering work on the chemical defence system of Lactarius species. Vellerol (10.8) and vellerdiol (10.20) were first isolated from extracts of Lactarius vellereus made at different times after grinding the mushrooms (27). The reduction of either... [Pg.165]

Part 6 also includes a few isomarasmanes (6.9-6.11) and nor-marasmanes (6.12-6.22). The former are synthetic compounds and were obtained by thermal isomerization of the corresponding marasmanes (see chemical part). The 13-normarasmane isomers 6.12 and 6.13 are among the few known norsesquiterpenes of Lactarius, The two compounds were isolated (58) together with compound 6.6 from an ethanol extract of Lactarius vellereus. The normarasmane ketones may derive in mushrooms from lactaropallidine (6.5) by 3-deformylation and oxidation at C-7. [Pg.88]
