TERPENOID AND PHENOLIC CONSTITUENTS OF SPOROPHYTES AND SPORES FROM THE LIVERWORT PELLIA EPIPHYLLA

抄録

  Sporophytes and spores from the liverwort Pellia epiphylla (L.) Corda have been examined for their secondary metabolites and compared to those from the gametophytes. The sporophytes contained five africanane-type sesquiterpenes, epi-swartzianin A, 9(15)-africanene, isoafricanol, leptographiol, and the new 10β-hydroxy isoafricanol, the new humulane derivative 1,8-humuladien-5-ol, caryophyllene oxide, phytol, and (1,2)-bis-nor-phytone. Further substances were palmitic acid, linolic acid methyl ester, 7, 10, 13-hexadecatriene acid methyl ester, octadecanol and three bisbibenzyls: perrottetin E, 10'-hydroxy perrottetin E and 10'-hydroxy perrottetin E-11-methyl ether. Caffeic and ferulic acid methyl esters could be obtained from the more polar extract along with four flavones: luteolin, luteolin-7-methyl ether, luteolin-7,3'-dimethyl ether and the new luteolin-5,7,3'-trimethyl ether. The spores contained isoafricanol and 1,8-humuladien-5-ol.
