Chemical Constituents Of The Camellia Oleifera Aberl.

Camellia oleifera Abel. belongs to Camellia Linn of Theaceae. In China it is distributed in southwest and southeast, across 17 provinces. Currently were contained in 2015 edition of Ch P. The medicinal parts of this plant are oil, s eed, root, flower, leaf and so on. Meanwhile Camellia oleifera Abel. also our basic edible oil woody species. It contains many chemical constituents includin g saponins, flavonoids, tannins and so on. The pharmacological effects is anti-i nflammatory, anti-bacterial, ant-mutation, antineoplastic and so on. Particularly a ntineoplastic. To explore the potentialvalue Camellia oleifera Abel., We studied the chemical constituents of the Camellia oleifera Abel. on the basis of previ ous research. We gain 31 compounds from stems and seeds with 95% ethanol extract by using of resin, silica gel, ODS silica gel, Sephadex LH-20, medium pressure column chromatography and Preparative high performance liquid chro matography. And we identified 23 compounds whose structures were elucidated by chemical propertyes, and spectroscop analyses, of which 8 were determine d as new. They are composed of(i) six lignans: 5-Benzofuranpropanol, 2, 3-di hydro-2-(4-hydroxy-3-methoxyphenyl)-3-(hydroxymetyl)-(2S, 3R)-spectra(1), α-C onidendrin(2), Syringaresinol(3),(-)-Medioresinol(4),(-)-Pinoresinol(5), 3’,4-O-dimethylcedrusin(6);(ii) one flavone: SkullcapflavoneⅡ(7);(iii) three Trite rpenoids: Betulinic acid(8), Oleanolic acid(9), Ursolic acid(10);(iv) one phe nylpropanoid glycosides: Acteoside(11);(iiv) twelve triterpenoid saponin: 3-O-β-D-glucopyranosyl-(1→2)-β-D-xylopyranosyl-(1→3)-[β-D-glucopyranosyl-(1→2)]-β-D-glucuronopyranosyl-22α-angeloyloxyolean-12-ene-15α,16α,28-triol(12), 3-O-β-D-glucopyranosyl-(1→2)-β-D-xylopyranosyl-(1→3)-[β-D-galactopyranosyl-(1→2)]-β-D-glucuronopyranosyl-22α-angeloyloxyolean-12-ene-15α,16α,28-triol(13), 3-O-β-D-xylopyranosyl-(1→2)-α-L-arabinopyranosyl-(1→3)-[β-D-glucopyranosyl-(1→2)]-β-D-glucuronopyranosyl-22α-angeloyloxyolean-12-ene-15α,16α,28-triol(14), 3-O-β-D-xylopyranosyl-(1→2)-α-L-arabinopyranosyl-(1→3)-[β-D-galactopyranosyl-(1→2)]-β-D-glucuronopyranosyl-22α-angeloyloxyolean-12-ene-15α,16α,28-triol(15), 3-O-β-D-xylopyranosyl-(1→2)-β-D-galactopyranosyl-(1→3)-[β-D-galactopyranosyl-(1→2)]-β-D-glucuronopyranosyl-22α-tigloyloxyolean-12-ene-23-aldehyde-16α,28-diol(16), 3-O-β-D-xylopyranosyl-(1→2)-β-D-galactopyranosyl-(1→3)-[β-D-galactopyr anosyl-(1→2)]-β-D-glucuronopyranosyl-22α-angeloyloxyolean-12-ene-23-aldehyde-16α,28-diol(17), 3-O-β-D-xylopyranosyl-(1→2)-β-D-galactopyranosyl-(1→3)-[β-D-galactopyranosyl-(1→2)]-β-D-glucuronopyranosyl-22α-angeloyloxyolean-12-ene-16α,28-diol(18), 3-O-β-D-xylopyranosyl-(1→2)-β-D-galactopyranosyl-(1→3)-[β-D-g alactopyranosyl-(1→2)]-β-D-glucuronopyranosyl-22α-O-(2-methylbutyloyl)-12-ene-23-aldehyde-16α,28-diol(19), 3-O-β-D-glucopyranosyl-(1→2)-β-D-galactopyranos yl-(1→3)-[β-D-galactopyranosyl-(1→2)]-β-D-glucuronopyranosyl-22α-tigloyloxyole an-12-ene-23-aldehyde-16α,28-diol(20), 3-O-β-D-galactopyranosyl-(1→2)-β-D-xyl opyranosyl-(1→3)-[β-D-galactopyranosyl-(1→2)]-β-D-glucuronopyranosyl-22α-ange loyloxyolean-12-ene-15α,16α,28-triol(21), 3-O-β-D-glucopyranosyl-(1→2)-β-D-xy lopyranosyl-(1→3)-[β-D-glucopyranosyl-(1→2)]-6’-O-methyl-β-D-glucuronopyranos yl-22α-angeloyloxyolean-12-ene-15α,16α,28-triol(22), 3-O-β-D-glucopyranosyl-(1→2)-α-L-arabinopyranosyl-(1→3)-[β-D-galactopyranosyl-(1→2)]-β-D-glucuronopyr anosyl-22α-tigloyloxyolean-12-ene-23-aldehyde-16α,28-diol(23). Among them, c ompounds 14, 16, 17, 18, 19, 20, 21 and 22 were new Compounds; 1~8, 10 and 11 were isolated from Camellia Linn for the first time.
