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 (UFLC), and soil samples were analyzed by spectrophotometric methods. We found that both paeonol and paeoniflorin contents increased with plant age and also increased from south to north location in 6-years old plants but not in younger ones. We found that soil Mg2+, Ca2+, organic matter, and pH value had positive effects both on paeonol and paeoniflorin contents. Our study highlights the importance of plant age and geographical location on paeonol and paeoniflorin contents of Paeonia ostii roots
