Abstract
Paeonol and paeoniflorin, available in Paeonia ostii roots, are active compounds applicable for curing breast cancer and neuropathic pain. We investigated the impacts of growing locations and plant age on paeonol and paeoniflorin contents of the roots in Paeonia ostii from 3 to 6-year-old plants growing in the south, middle and north latitude of Anhui province, China. Root samples were analyzed by Ultra-Fast Liquid Chromatography and soil samples were analyzed by spectrophotometric methods. We found that paeonol contents increased with plant age and increased from south to north location. Similarly, paeoniflorin contents increased with plant age, and increased from south to north location in 6-old-year plants but not in younger plants. We found that soil magnesium, calcium, organic matter and pH had positive effects on paeonol and paeoniflorin contents. Our study highlights the importance of plant age and growing location on paeonol and paeoniflorin contents of Paeonia ostii roots.
