“…Compounds 4-38 were identified by comparison with published data. 1 Ϫ1 in the IR spectrum and the l max at 290, 231, and 213 nm in the UV spectra suggested the presence of a hydroxyl group and an aromatic ring. Its 1 H-NMR spectrum had signals for six angular methyl groups, two isopropyl groups, and one methoxy group.…”

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).

Publication details, including instructions for authors and subscription information: Avenue Escadrille N o m n d i e -N i e m n , Case 56113397 Marseille Cbdex 13, FranceABSTRACT: GUMS analysis of the leaf oil of Cyptomriajaponica D. Don obtained from Reunion allowed us to identify more than 70 compounds thanks to our SPECMA data bank. Among the volatiles, monoterpene hydrocarbons (45%), monoterpene alcohols (lo%), monoterpene esters (2%), sesquiterpenes (25%) and diterpenes (12%) have been found. The presence of a moderate amount of a-kaurene (10%) and its 16-hydroxylated derivative (0.6%) was noted. The composition of the C.japonica from Reunion was found to be similar to that originating from Japan. Unidentified sesquiterpene and diterpene derivatives require further attention.

In our study, we investigated the antioxidant effect of methanol extract from the leaves of Picrasma quassioides (PQ) and Chamaecyparis obtuse (S. et Z.) ENDL (CO). Total polyphenol contents of methanol extracts from PQ and CO varied from 138.3 to 367.52 μg/mg and total flavonoid contents varied from 8.12 to 46.41 μg/mg. Contents of polyphenol and flavonoid in PQ were found to be extremely high. In addition, the methanol extract of PQ had a higher antioxidant activity in both DPPH (4.79 μg/ml) and ABTS (7.21 μg/ml) compared to other plants (CO). Based on the results of the FRAP assay, PQ showed a value of 8.52 μmol/μg and CO exhibited a value of 1.77 μmol/μg. The methanol extracts from the leaves of PQ showed the highest radical-scavenging activity in various antioxidant systems.
