[Chemical studies on peptidepolysaccharides of Ganoderma lucidum (W. Curt. Fr.) Karst]

Seven homogeneous peptidepolysaccharides have been obtained from the fruit-body of Ganoderma lucidum. The main constituents are TGLP-2, TGLP-3, TGLP-6 and TGLP-7, whose molecular weights are 20.9 x 10(4), 4.5 x 10(4), 3.2 x 10(4) and 10 x 10(4) respectively. TGLP-2 is a heteroglycan peptide, TGLP-3 and TGLP-6 are glycan peptides and TGLP-7 is a galactan peptide.
