The 70% ethanol extraction and water extraction solution were prepared from petioles, trophophylls, sporophylls, sporangia and sporophylls without sporangia of Pyrrosia petiolosa. The active ingredients and antioxidant activity in the extraction, including chlorogenic acid (Chl), mangiferin (Man), caffeic acid (Caf), rutin (Rut), total flavonoids (TF), total phenols (TP) were assayed. There were significant differences among the five parts for active ingredients and antioxidant activity (P<0.05). TF and TP in sporophylls without sporangia were the highest, (129.46±4.03)mg/g and (47.85±2.98)mg/g respectively, which was similar to trophophylls. The antioxidant activity of ethanol extraction was higher than that of water extraction in each part. The antioxidant activity of each part was trophophylls > sporophylls without sporangia > sporophylls > petiole > sporangia. Chl and Rut in sporophylls without sporangia and trophophylls were higher. Man and Caf acid in trophophylls were the highest, which was significantly higher than that of the other four parts (P<0.05). Besides, the ABTS + free radical scavenging capacity, DPPH free radical scavenging abilities and total antioxidant capacity of different parts of P. petiolosa were positively correlated with active components (r=0.69~0.98). According to the comprehensive analysis, trophophylls had more effective components and stronger antioxidant activity. The study could provide scientific basis for the development and utilization of Pyrrosia.

Key words: Pyrrosia petiolosa, total flavonoids, total phenols, antioxidant activity
