A rare class of onoceranoid-type triterpenoids, represented by lamesticumin A (1), the ethanolysis product of lamesticumin A (2), lamesticumins B-F (3-7), lansic acid 3-ethyl ester (8), and ethyl lansiolate (9), along with four known analogues were isolated from the twigs of Lansium domesticum. Their structures were elucidated on the basis of extensive spectroscopic analysis, and the absolute configuration of C-21 in compound 7 was assigned by using Snatzke's method. Compounds 1-9 exhibited moderate antibacterial activity against Gram-positive bacteria.

“…The bark of Picea abies was shown to contain 3-methoxy-serrat-14-en-21-ol (9), 21-methoxy-serraten-14-one (6) and 3-methoxy-serrat-14-en-21-ol (10; Norin and Winell, 1972a). PJ1 (9) and PJ2 (10) were extracted from Picea glehni (Sakhalin spruce; Tanaka et al, 2000) and Picea obovata (Siberian spruce; Chernenko et al, 1992b). They were accompanied by 3-methoxy-serrat-14-en-21-yl formate and piceanonol A in the former and by compounds 1 and 5 (both isomers) in the latter.…”

International audienceIn the frame of a study aimed at defining new soil molecular biomarkers that could attest to former land use and that could also be screened in lake sediments for palaeoenvironmental reconstruction, we analysed the 2-4 cm depth layer of a soil developed under a conifer forest in the Lake Aydat catchment (French Massif Central). The lipid fraction of the sample contained 12 serratenoids bearing at least a methoxyl (OMe) group at C-3 or C-21 and various additional functional groups (alcohol, ketone or acetate). A survey of the literature provided indubitable evidence that these compounds are typical for Pinaceae species, in agreement with the surrounding vegetation at the sampling site. Due to the economic and ecological importance of the taxa, the presence of these highly specific compounds in soil, sediments or peat should therefore help in unravelling the timing of forestry activity

“…Thus, the structure of the second new triterpenoid was determined to be 21β-hydroxyserrat-14-en-3β-yl-formate. The known isolated compounds serratenediol (3), [12] 21-episerratenediol (4), [12] serrate-14-en-3,21-dione (5), [12] 21β-hydroxyserrat-14-en-3β-yl-acetate (6), [13] serrat-14-en-3β-yl-acetate (7), [14] lycoclavanol (8), [12] α-onocerin (9), [15] and α-onoceradienedione (10) [16] were identified by comparing their spectroscopic data to previously published data.…”
