Saxifraga leaves contain bergenin, quercitrin, quercetin, gallic acid, protocatechuic acid, succinic acid and methyl fumaric acid. The stem contains catechol. Roots contain volatile oil. In addition, arbutin, chlorogenic acid, quercetin -5-O- glucoside, norbornin, amino acids, potassium nitrate and potassium chloride were also isolated from Saxifraga. Phenolase contained in chloroplasts can oxidize cis-caffeic acid into corresponding protoquinone, and protoquinone naturally oxidizes to produce aesculus bark.
