摘要
A physiologically active substance is extracted from pine seed shells by (1) immersing the pine seed shells in aqueous alkali to extract the active substance; (2) filtering the solution; (3) concentrating the filtrate; (4) adjusting to acidic pH; (5) lyophilising to obtain the active substance in powder form. The active substance is mainly composed of acidic polysaccharides.
