The chemical components of the volatiles from the leaves and branches of Larix principis-rupprechtii were analyzed by GC-MS, with their allelopathic effects on the seed germination and growth of L. principis-rupprechtii itself investigated. The results indicated that the volatiles contained 20 major
A highly branched arabinogalactan isolated from Larix principis-rupprechtii and subjected to sulfation derivatization to promote their antitumor bioactivity. Several structural features of the sulfated arabinogalactans (S-LAG) were investigated: molecular weight, monosaccharide constitution, and
