[Chemical constituents, biological activities and quality control of plants from genus Pyrola].

Plants from the genus Pyrola are widely distributed in North Temperate zone. The quinones, phenol glycosides, terpenoids, flavonoids and volatile oil compounds have been identified from these plants. The in vivo and in vitro studies have shown that the genus Pyrola plants exhibit a wide range of pharmacological properties, including antioxidant, antitumor, antibacterial, anti-ischemia and anti-inflammatory activities. Based on analysis of the literature of the genus Pyrola plant, this review summarized the research on chemical constituents, pharmacology and quality control in recent years which can provide evidences for further investigation on the genus Pyrola plants.
