Lipophilic extractive metabolites from needles and defoliated twigs of Pinus armandii and P. kwangtungensis were studied by GC-MS. Needles of P. armandii contained predominantly 15- O -functionalized labdane type acids (anticopalic acid), fatty acids, nonacosan-10-ol, sterols, nonacosan-10-ol and
Diverse biological activities of hot-water and alkali extracts of lignified materials were reviewed and the molecular species involved are discussed. Materials tested included pine cone of Pinus parviflora SIEB. et Zucc., wood chips of slash pine, Douglas fir, and tallow wood, and two basidiocarps,
