Abstract: The solubility, UV spectrum, heat stability, light stability and antioxidation activity of extractives extracted from the bark of pinus yunnanensis with ethyl acetate-water were studied. The results showed that the extractives had good water solubility, light and thermal stability(≤60℃) and maximum absorption wavelength (λmax) at 280 nm. The results also showed the OPCs had good antioxidation property.

Key words: the bark of pinus yunnanensis, extractives, property
