Russula delica complex preparation consists of several phisiological active substances from the liquid fermentation extract of Russula delica. The physio-chemical properties and spectral analyses (UV, IR, NMR, MS, HPLC) show that these substances are antibiocitic 82-101A (10-20 mg/ml), antibiotic B (5-10mg/ml), and endogenous hormones of Z(2.6mg/ml), GA3(7.4mg/ml), ABA(0.2 mg/ml) and KT(0.3 mg/ml). Indoor and outdoor biological activity test of dilutions of the complex preparation 1:50 and 1:100 on Pinus massoniana Lamb, Pinus taiwanensis Hayata and Pterocarya stenoptera DC. show that the preparation has biological effects of raising physiological activity of seedlings, promoting the growth and increasing antibiotic ability of them.
