The flower and leaf oil of Hypericum triquetrifolium Turra (Guttiferae, Hypericoideae) from Calabria (Italy) were studied by GC and GC-MS. The major components identified in each oil were n-nonane (8%, 15%), β-pinene (8%, 4%), α-pinene (13%, 10%), myrcene (16%, 5%), β-caryophyllene (5%, 11%), germacrene-D (10%, 13%), sabinene (13%, 3%) and caryophyllene oxide (5%, 12%) in the leaf and flower oils, respectively. The aerial parts of the same plant were also analysed by SPME. The SPME analysis showed higher yields of undecane (14%, 10%) and β-caryophyllene (14%, 10%) in comparison with the corresponding hydrodistillation oils, in addition to α-pinene, β-pinene, sabinene and myrcene, amounting to (9%, 6%), (7%, 4%), (1%, 9%), (1%, 10%) for the leaves and flowers, respectively.

Abstract:The content and distribution of stilbenes and resin acids in Scots pine (Pinus sylvestris) and spruce (Picea abies), sampled in central Norway, have been examined. The contents of pinosylvin stilbenes in pine heartwood/living knots were 0.2-2/2-8 % (w/w). No stilbenes could be detected in spruce (Picea abies). The resin acid contents of pine sapwood/heartwood and knots were 1-4 and 5-10 % (w/w), respectively. Minor amounts of resin acids (<0.2/<0.04 %w/w) were identified in spruce wood/knots. The lignan content in knots of Norwegian spruce was 6.5 % (w/w). Diastereomerically pure hydroxymatairesinol (HMR, 84 % of total lignans) was readily isolated from this source since only minor quantities (2.6 % of total lignans) of the allo-HMR diastereomer was detected. Insignificant amounts of lignans were present in the sapwood. Lignans could not be detected in the sapwood or knots of Norwegian sallow (Salix caprea), birch (Betula pendula) or juniper (Juniperus communis).

The Japanese cedar, Cryptomeria japonica D. DON. (Taxodiaceae) is a widely distributed conifer called sugi in Japanese. This wood is the most popular building material for Japanese housing. Although many cedar cores are reddish brown, about 20% are black, as a result of genetic factors, physical damage, infection of fungus, etc., and are called kurojin in Japanese. Chemical research on the terpene components of cedar cores is limited to the reddish brown ones. [1][2][3][4][5][6][7][8][9] This prompted us to examined the terpene constituents of black heartwood.Shaved chips (3.92 kg) of black heartwood were exhaustively extracted with MeOH at room temperature for 4 weeks. The extract was partitioned between H 2 O and EtOAc. Repeated separation of the EtOAc-soluble portion by chromatography over ordinary-phase silica gel and reverse-phase silica gel furnished a novel abietane, sugikurojin A (1), dimeric abietanes, and sugikurojins B (2) and C (3), along with known compounds formosaninol (4), 10) a-muurolene (5), 11) d-cadinene (6), 12) calamenene (7), 13,14) T-cadinol (8), 15) cubenol (9), 15) epi-cubenol (10), 16,17) cubebol (11), 16,17) 21) 7(14),10-bisaboladien-1-ol-4-one (16), 22) 2,7(14),10-bisabolatrien-1-ol-4-one (17), 23) 7 (14),10-bisaboladien-1,4-diol (18) A-C (1-3) were isolated from the black heartwood of Cryptomeria japonica. The structure of sugikurojin A was deduced to be 19-hydroxy-6,7-dehydroferruginol on the basis of extensive NMR experiments. Sugikurojin B was a dimer of 6,7-dihydroxyferruginol and 6,7-dehydroferruginol with a 6-O-11 linkage. Sugikurojin C was a dimeric ferruginol with 6-O-7 and 7-O-6 linkages. Also obtained in this investigation were the known compounds formosaninol (4), 15 sesquiterpenes (5-19), 16 diterpenes (20-35), three phenylpropanoids (36-38), and a phenolic compound (39).
