Studied the morphological characteristics o f plant in the laboratory, determined the scientific name by the method o f comparing morphological characteristics, based on the classification key genus Ardisia Staff. Studied on microscopic characteristics: roots, stems and leaves were cut, bleached, and stained by double staining method, stem, leaves, and roots powder were applied to the specimen by pressing drop method. Identified the major groups of compounds In medicinal herbs by characteristic chemical reactions. Determ ined o f total polyphenol content by photom etric method. Results: A data set on m orphology, anatom ical structure a n d m edicinal pow der characteristics (roots, stems, leaves) o fA rd isia gigantifolia S tapfw as built. Prelim inary study o f phytochem istry also showed that there are flavonoids, coum arins, tannins, organic acids a n d sterols in the plant. The total polyphenol content in the leaves collected in Yen Bai in M ay reached the highest level o f 4.05%. Conclusion: A data set on morphology, anatom ical structure an d m edicinal pow der characteristics (root, stem, leaf) o fA rd isia gigantifolia Stap fand prelim in ary chem ical com position o f this species has been built.
