Abstract

Imperata cylindrica is a medicinal plant native to southwestern Asia and the tropical and subtropical zones. To date, 72 chemical constituents have been isolated and identified from I. cylindrica Among these compounds, saponins, flavonoids, phenols, and glycosides are the major constituents. Investigations of pharmacological activities of I. cylindrica revealed that this edible medicinal herb exhibits a wide range of therapeutic potential including immunomodulatory, antibacterial, antitumor, anti-inflammatory, and liver protection activities both in vivo and in vitro. The purpose of this review is to provide an overview of I. cylindrica studies until 2019. This article also intends to review advances in the botanical, phytochemical, and pharmacological studies and industrial applications of I. cylindrica, which will provide a useful bibliography for further investigations and applications of I. cylindrica in medicines and foods.

Highlights

  • The genus Imperata cylindrica. a member of Gramineae family, is a perennial rhizomatous plant that can grow on soils with a vast range of nutrients and moisture [1]

  • A variety of classical formulas containing I. cylindrica is widely used in traditional Chinese medicine (TCM) clinic

  • Other studies have shown that aqueous extract of I. cylindrica can enhance the activity of superoxide dismutase (SOD) in liver and brain tissue of mice with alcoholism, inhibiting the activity of hydroxyl radicals, reducing the level of malondialdehyde, improving the body’s antioxidant capacity, and alleviating the pathological damage of free radicals to liver and brain tissue

Summary

Introduction

The genus Imperata cylindrica. a member of Gramineae family, is a perennial rhizomatous plant that can grow on soils with a vast range of nutrients and moisture [1]. A member of Gramineae family, is a perennial rhizomatous plant that can grow on soils with a vast range of nutrients and moisture [1]. It is widely distributed in southwestern Asia and is native to the tropical and subtropical zones. In traditional Chinese medicine (TCM), the rhizome of Imperata could be used either alone or in combination with other herbal medicines to cure hematuresis, jaundice with damp-heat pathogen, emesis, hemorrhage and reducing fever and causing diuresis, anti-fever, and anti-inflammatory. The combination of I. cylindrica, Artemisia capillaris Thunb, and Gardenia jasminoides Ellis could significantly dispels dampness and heat This is used widely in jaundice with damp-heat pathogen. We provide a systematic overview of the available information of I. cylindrica including traditional uses, botany, nutritional composition, physiochemical, pharmacology, and industrial use
