Abstract
Pyrrosia petiolosa (Christ) Ching, Polypodiaceae, is an important medicinal pteridophyte used for the treatment of nephritis and bronchitis, while P. davidii (Giesenhagen. ex Diels) Ching, Polypodiaceae, often substitutes medicinal Pyrrosia in clinic. The present study was aimed to compare the pharmacognosy of P. petiolosa and P. davidii, including plant morphology, microscopic characteristics, physico-chemical parameters, UV and IR spectrum, and HPLC fingerprint. It was revealed that the two herbs had basically similar pharmacognostical characteristics but with certain differences. The present study contributes to the standardization and verification of these medicinal materials.
