Abstract: Oligomeric proanthocyanidins(OPCs) were prepared from the bark of Simao pine by extraction with solvents such as methanol,50% methanol,70% acetone and 50% acetone,and precipitation of petroleum ether. The extracts were compared with the OPCs reference material from Tianjin Jianfeng Company by IR spectrum. The OPCs contents in extracts were deter mined by UV method. The results showed that the OPCs could be extracted from Simao pine bark with all above solvents. The extraction yield was 1.08 %,1.41 %,1.78 % and 2.53 %,respectively.

Key words:  bark of Simao pine;oligomeric proanthocyanidians;extraction
