Phytochemistry and Pharmacological Activity of Plants of Genus Curculigo: An Updated Review Since 2013

The genus Curculigo, as a folk herbal medicine, has been used for many years in China, treating impotence, limb limpness, and arthritis of the lumbar and knee joints. The last systematic review of the genus Curculigo was written in 2013, scientifically categorizing the phytochemistry and biological activities. Hitherto, the original compounds and their pharmacological activities were presented as the development of this genus, but there is not an updated review. To conclude the progression of the genus Curculigo, we collected the new literature published from 2013 to 2021 in PubMed, Web of Science, Google Scholar databases, and the Chinese National Knowledge Infrastructure. The novel chlorophenolic glucosides, curculigine, phenolic glycosides, orcinosides and polysaccharides were isolated from Curculigo. The new analyzing methods were established to control the quality of Curculigo as a herbal medicine. In addition, the pharmacological effects of Curculigo focused on anti-diabetes, antibacterial, anti-inflammatory, osteoporosis, antioxidation, etc. The antitumor and neuroprotective activities were newly explored in recent years. The application of herbal medicine was gradually developed in scientific methods. The medicinal value of the genus Curculigo needs to further investigate its pharmacological mechanisms. This new review offers more insights into the exploitation of the pharmacological value of the genus Curculigo.

This will help researchers understand future research trends by bridging the gap between documented literature and contemporary uses.MethodologyAll the systematic literature data or information on the genus Morinda was collected via selected electronic databases, including Scopus, PubMed, Web of Science, Springer, Medline, ChemSpider, Taylor and Francis, Google Scholar, SciFinder, ScienceDirect and Wiley. Relevant book chapters, Wikipedia and books were also explored.ResultsThe study reveals that different parts of Morinda plants have been extensively used for folkloric therapeutic purposes and are a plethora of mineral or nutritional benefits and secondary metabolites. Several classes of bioactive compounds have been elucidated from Morinda plants via spectroscopic and chromatographic phytochemical analyses. Compounds such as terpenoids, glycosides, anthraquinones, polyphenols, steroids, saponins and reducing sugars are among the bioactive substances reported in the genus. Plant extracts, fractions and isolates of Morinda plants have exhibited pronounced antidiabetic, antioxidant, antiplasmodial, antidepressant, wound healing, anticancer, and anti-inflammatory effects (in vitro and in vivo). These pharmacological activities exhibited could be linked to the presence of secondary metabolites reported. The applications of this genus is well documented in textile, metallurgical, agrochemicals and food industries.ConclusionA number of reports on Morinda showed significant therapeutic effect against several diseases such as cancer, dermal infection, diabetes, inflammation, malaria, typhoid, cholera and memory loss, however, there were several drawback in previous reports including mechanism of action, drug dose, controls and toxicological data of extracts or isolates. In view of this, further studies should emphasis on targeting active secondary metabolites which responsible for the therapeutic activities, structural elucidation and toxicological assessment. Furthermore, industrial uses require authentication.
