The yield of wax D fraction from P6 (Scotochromogen) as described by Aebi et al. was as low as 0.3%. The acid hydrolysate of wax D from P6 yielded mannose and galactose as sugar constituents, but no arabinose. Wax D from P6 with melting point at 40°C contained also muramic acid. It showed remarkable adjuvant activity in an amount of lOμg as judged by corneal test.
