Main Article Content

Aunyachulee Ganogpichayagrai


Introduction: Acanthopanax trifoliatus or Phak-pam has been popularly used as both medicinal plant and food plant in Northern of Thailand. Objective: The present study aims to investigate the pharmacognostic specifications to authenticate A. trifoliatus leaves. Methods: Leaves of A. trifoliatus from 12 sources throughout Thailand were collected, then morphological and physiochemical determinations following WHO guideline of quality control methods for medicinal plant materials were used to investigate leaves samples. Results: Morphological identification revealed remarkable microscopic characters were rosette crystals of calcium oxalate and anisocytic stomata. Physico-chemical parameters including; loss on drying, total ash, total acid insoluble ash, water content, ethanol soluble extractive and water soluble extractive values were found to be 1.08±0.17, 10.52±1.33, 1.67±0.30, 9.87±1.32, 6.76±4.41 and 6.67±0.57, respectively. A. trifoliatus leaves contained traces of volatile oil. Conclusion: This study provided useful information of pharmacognostic specification that could be used for authentication, identification and quality control of A. trifoliatus leaves.
