Thatree Phadungcharoen and Orawan Theanphong
Abstract
Curcuma petiolata Roxb. (Zingiberaceae) is used in ethnomedicine in many countries. According to morphological similarities and the processing of medicinal plants into powder for preparation in several dosage forms changing morphological characters, it causes difficulty to identify species. Microscopic examination is a conventional method for identification crude drugs. In this study, transverse and longitudinal sections of the fresh and rhizomes powdered of C. petiolata were investigated under microscope. The results showed the presence of epidermis, cork, parenchyma containing simple starch grains or some yellowish oil and scattered vascular bundles. The study of powder rhizome showed very abundant flattened-rounded to oval simple starch grains and oil droplets, very occasional pale brown cork, occasional non-lignified spiral and scalariform vessels, parenchyma, yellowish septate fiber and rarely seen epidermis. The diagnostic character of the rhizome of C. petiolata was yellowish septate fiber.
