Lipid composition
The lipid composition of H. punicea has been analyzed using GLC, GC/MS and 1H NMR (Yokokawa and Mitsuhashi, 1981). As a percentage of dry weight, the total (saponifiable) lipid content in this species is a low 3.6%, while unsaponifiable lipids were 11.2%. Of this unsaponifiable fraction, 31.1% was comprised of Δ5,7-sterols. This fraction was further determined to be 78.8% ergosterol, and 21.2% ergosta-5,7-dien-3β-ol.
Medicinal properties
Anti-tumor effects
Polysaccharides extracted from the mycelial culture of H. punicea and administered intraperitoneally into white mice at a dosage of 300 mg/kg inhibited the growth of Sarcoma 180 and Ehrlich solid cancers by 90% and 100%, respectively (Ohtsuka et al., 1973).
