The chemical composition of lichens [ ] containing black tea stains hormone ( atranorin ), lecanoric acid ( lecanoric acid ), different lecanoric acid ( isolecanoric acid ), ( orcinol orcin, i.e. 3, 5 - two hydroxy toluene ) and polysaccharide.
Pharmacological action [ ]
1 kill sperm, the antibacterial effect of water decoction of Parmelia share is the main component of orcinol and a series of semi synthetic fur colour ester, can inhibit the sperm activity. Orcinol and sperm concentrations as low as 4mg / ml, below the International Planned Parenthood Federation stipulates a minimum concentration. Orcinol ( i.e. 3, 5 - two hydroxy toluene ) in vitro of Trichophyton rubrum, Epidermophyton floccosum, Candida albicans, Sporothrix fungus has good antibacterial effect.
2 resistance to radiation and free radical scavenging effects of mice with 9Gy ( 900rad ) 60 Co gamma ray whole body irradiation before an intraperitoneal injection of stone coarse polysaccharide in aqueous solution of 150mg / kg, can improve the survival rate of mice 22.5%-55%, is both an available and slow release characteristics of long-term radiation protective agents, the radiation effect is orcinol strong. Orcinol in vitro test has significant scavenging hydroxyl free radical effect ( OH ), its effects are natural antioxidants vitamin C and OH scavenger mannitol 4.9 and 22.5 times.
