Ethnopharmacology, genetic diversity, phytochemistry and pharmacological effects of Panax vietnamensis Ha et Grushv.: A review

Abstract

Ginseng is considered as a beneficial herbal remedy and over recent years its efficacy and safety have been verified in clinical therapy. There are two typical species of ginseng concluding Asian and American ginseng. The varieties of both species have been applied for commercialized materials in different stages of processing from raw to processed products. Panax vietnamensis Ha et Grushv. (P. vietnamensis) belongs to Asian ginseng and has been utilized as effective herbal remedy. P. vietnamensis is believed to improve immune response, longevity and consequent health. There are more than 300 bioactive compounds have been isolated from P. vietnamensis and classified in various groups, such as ginsenosides, flavonoids, phenolics .... These biological activities consist of anti-tumor, anti-inflammatory, neuroprotective and anti-stress, which are validated by in vitro and in vivo studies. In this review, we systematize the literatures about ethnopharmacology, major bioactive constituents, and toxicology of P. vietnamensis, which were certified by various studies. Furthermore, we also summarize the current method to micro-propagate and lists of extracting sources of bioactive compounds (root, leave, stem…) and the solvents deployed during extraction process. Therefore, this review would provide the firm-evidences and premise for the therapeutic potentials of P. vietnamensis in the future.
