INVESTIGATION ON THE MORPHOLOGICAL CHARACTERISTICS AND PRELIMINARY ANALYSIS OF CHEMICAL CONSTITUENTS OF PYRROSIA LANCEOLATA (L.) FARW.
Main Article Content
Abstract
Background: Ferns (Polypodiophyta) are a large and diverse phylum in the plant kingdom. Many ferns among many other plants showed remarkable activities such as: anti-oxidative, anti-bacterial, anti-inflammatory effects, .... In particularly, some species in the genus Pyrrosia in Polypodiaceae family are commonly used in the traditional medicine for the treatment of the urinary tract inflammatory diseases. In there, P. lanceolata is a rich source of medicinal ferns in Vietnam, but few studies on this species have been carried out. Objectives: To investigate on the plant morphology, microscopic characteristics of species P. lanceolata (L.) Farw. in order provide the reliable information for the taxonomical identification of this species in genus Pyrrosia. Materials and methods: The fresh plants were collected Tao Dan Park (Ho Chi Minh city), analyzed and described the morphological characteristics. The preliminary phytochemical screening was conducted by the modified Ciuley method. Results: The plant “Lưỡi mèo tai chuột” was identified as P. lanceolata (L.) Farw., based on the morphological characteristics, anatomical features and phytochemical constituents (including: essential oils, flavonoids, proanthocyanidins, tannins, organic acids, reducing compounds, and triterpenoids). Conclusions: Morphological, anatomical, plants powder characteristics of P. lanceolata (L.) Farw. supported for taxonomical identification and quality control of this plant in future studies. The preliminary study results on the phytochemical constituents will provide basic information for further research on the chemical composition as well as pharmacological effects of these species.
