Abstract:
Phenolic acids of rhizosphere soil of Panax notoginseng were identified and the contents were determined. HPLC-MS and HPLC were used. Compared with the literature and standard reference, identification and content de-termination were given on phenolic acids of rhizosphere soil of Panax notoginseng in Wenshan, Yunnan province. The results showed that six types of phenolic acids were detected from the extract of rhizosphere soil of Panax notogin-seng, which were p-hydroxybenzoic acid, vanillic acid, syringic acid, p-coumaric acid, ferulic acid and benzoic acid. The content of p-coumaric acid showed the highest concentration of 24.01 μg·g-1, while syringic acid had the lowest concentration of 1.26 μg·g-1. The sequence of content in the rhizosphere soil of Panax notoginseng from top to bot-tom was p-coumaric acid, vanillic acid, benzoic acid, p-hydroxybenzoic acid, ferulic acid and syringic acid. It was concluded that the rhizosphere soil of Panax notoginseng contained six types of phenolic acids, which were p-hy-droxybenzoic acid, vanillic acid, syringic acid, p-coumaric acid, ferulic acid and benzoic acid.
