Phenolic substances have been identified by the paper partition chromatography from four species of Japanese Pinus trees.The heartwoods of Pinus densiflora and P. Thunbergii always contained pinosylvin monomethyl ether, pinocembrin, pinobanksin, and "unknown I", and contained occasionally moreover dihydropinosylvin monomethyl ether and "unknown III". The heartwoods of P. pentaphylla var. Himekomatsu and P. Armandii contained dihydropinosylvin monomethyl ether, chrysin, strobobanksin, strobopinin, cryptostrobin, "unknown I", and "unknown II" in addition to pinosylvin, pinosylvin monomethyl ether, pinocembrin, and pinobanksin. As another phenolic substance, pinostrobin was found only in the heartwood of P. pentaphylla var. Himekomatsu. "Unknown I" showed a red color with the diazotized benzidine reagent and had Rf value of 0.0 for the LINDSTEDT's standard solvent, "unknown II" had a pale yellow color and Rf value of 0.83,and "unkown III" had a very pale yellow color and Rf of 0.92.Also the sapwood of all samples contained a very small quantity of the heartwood phenols.The acetone extracts of bast and cork of all samples were stained into very clear red with the benzidine reagent. This shows that they contain probably much phenolic substances. But the experiments showed that they contained only a small quantity of some of the known pine phenols.
