The review provides an update on the traditional uses, geographical distribution, pharmacological activities, biosynthesis, and mechanisms of action of potent natural products derived from Cyperus species. Cyperus species are widely distributed in the tropical and subtropical regions across the globe. Cyperus is the second-largest genus in this family with about 950 species. Since 1964, a total of about 403 natural products have been isolated from 43 Cyperus species, including terpenoids (51.61%), flavonoids (17.37%), stilbenoids (6.45%), quinones (5.71%), aromatics (7.69%), coumarins (5.21%) and other compounds (5.96%). The isolated compounds displayed anticancer, antiviral, antidiabetic, antimicrobial, antidepressant, and other activities. Terpenoids and flavonoids are the most abundant class of natural products that have been isolated from Cyperus species. The biosynthesis of some terpenoids and flavonoids has been provided in the paper. Natural products isolated from Cyperus species have demonstrated interesting in vitro activities which warrant further scientific investigations.

Background: Since time immemorial, humans have identified several herbs to treat various ailments. With the advancement of science and state-of-the-art technologies, different herbal extracts and chemical constituents of herbs were identified as therapeutic targets. Cyperus rotundus, also called mustaka, is one of the most ancient herbs widely distributed in tropical and subtropical regions across the globe. The tuberous and aerial parts of the herb were identified to possess various pharmacological properties. Objectives: This review focuses on the various phytocompounds of mustaka and how these compounds exert pharmacological effects and their mode of action. The molecular and cellular effects of mustaka were also discussed based on the preclinical and clinical reports available using an array of in vitro, in vivo, and ex vivo methodologies. Methods: The information from Google Scholar, Science direct, PUBMED, were reviewed with a special focus on the mode of action of C. rotundus from the data on animal and preclinical experiments to treat various diseases. Conclusion: Based on the literature available on C. rotundus in Google Scholar, Science Direct, and PubMed, the pharmacological properties of mustaka were reviewed with a particular focus on its neuropharmacological activities. The mode of action of C. rotundus and its bioactive metabolites at the molecular biology level were demonstrated based on animal and preclinical experiments to cure various ailments.

... However, to the best of our knowledge, there is no evidence supporting the effect of active constituents of CRE in gynecologic disorders including endometriosis. In a previous study, we found that α-cyperone is the most abundant and active component of CRE [44][45][46][47]. In these regards, we have examined the anti-endometriotic effect of α-cyperone in human endometriotic 12Z cells. ...

Rhizomes of Cyperus rotundus have been widely used as a traditional medicine in Asia for the treatment of gynecological diseases. However, there is no scientific evidence demonstrating the effect of C. rotundus rhizomes on endometriosis, which is characterized by the adhesion of endometrial tissues outside the uterus, resulting in chronic and severe pelvic pain. The aim of this study was to investigate the effects of Cyperi rhizoma extract (CRE) on cell adhesion and the expression of pain-related factors (neurotrophins) in endometriotic cells, and to elucidate the underlying molecular mechanisms. CRE inhibited the adhesion of human endometriotic 12Z cells to peritoneal mesothelial Met5A cells using by adhesion assays. The mRNA expression of adhesion molecules [P-cadherin and matrix metalloproteinase (MMP)-2] was downregulated by CRE treatment. In addition, CRE significantly inhibited the mRNA expression of neurotrophins (BDNF, NGF, NT-3 and NT-4/5) in 12Z cells. Moreover, Akt overexpression markedly neutralized the inhibition of cell adhesion by CRE and expression of neurotrophins in 12Z cells. Furthermore, it was found that CRE suppressed NF-kB activation through the Akt pathway. These data suggest that CRE exerts anti-endometriotic activities by the inhibition of cell adhesion and neurotrophin expression, through the negative regulation of the Akt and NF-kB pathways in endometriotic cells.
... Resveratrol, piceatannol, and scirpusin B are all stilbene derivatives. As shown in Fig. 1, scirpusin B is a dimer of piceatannol and has been shown to exert various biological actions such as vasodilation [52], superoxide anion removal [53], inhibition of postprandial hyperglycemia [34], inhibition of a-amylase activity [34], protection of neurons from neurotoxins [54], anti-amyloid-b aggre- gation effect [54], and anti-human immunodeficiency virus activity [55]. Furthermore, scirpusin B has been reported to have stronger antioxidative effect and stronger nitric oxide (NO)-mediated vasodilation than piceatannol [52]. ...

Cardiovascular disease is a global health problem. According to the World Health Organization, ischemic heart disease was the leading cause of death globally in 2019, followed by stroke. The French paradox, which has been known since the early 1990s, describes the lower incidence of ischemic heart disease in French people despite the consumption of a diet rich in saturated fatty acids. This phenomenon has been attributed to the high intake of red wine, which is rich in polyphenols, namely, resveratrol and piceatannol. It is becoming clear that scirpusin B, a dimer of piceatannol, has anti-atherosclerotic properties such as vasodilation, antioxidant effects, and suppression of postprandial hyperglycemia; nonetheless, the effects of scirpusin B on the cardiovascular system have not been fully elucidated. This review aimed to describe the cardiovascular effects of piceatannol and scirpusin B on aortic and coronary artery dilation and cardiac function and to outline the cardiovascular effects of prostacyclin and nitric oxide, as these substances are involved in the vasodilatory effects exerted by these polyphenols.

Present study reports metabolites profiling, antioxidant, and antidiabetic effects of Cuscuta reflexa grown on Casearia tomentosa. The UHPLC-QTOF-MS/MS method was used to characterize phytochemicals in most potent extract. Thirteen bioactive compounds/metabolites including (2S)-3-(β-D-galactopyranosyloxy)-2-(hexanoyloxy)propyl nonanoate, 4-O-β-D-glucosyl-4-coumaric acid, isorhamnetin-3-O-glucoside, 7-(α-D-glucopyranosyloxy)-2,3,4,5,6-pentahydroxyheptanoic acid, 13S-hydroxyoctadecadienoic acid, astragaloside derivative, salicylic acid, oleanolic acid, citric acid, pinellic acid, quinic acid, caffeic acid derivative and caffeic acid-3-glucoside were detected in 80% hydroethanolic (HE) extract. Among different extracts (aqueous, 20–80% HE and pure ethanolic), 80% HE extract showed maximum TPC (186.19 ± 2.15 mg GAE/g DE) and TFC (106.50 ± 1.68 mg RE/g DE). A strong correlation was observed between TPC, TFC, DPPH radical scavenging (IC50 = 60.64 ± 1.74 µg/mL) and TAP activity (235.96 ± 1.33 mg AAE/g DE) of 80% HE extract among others. The same extract also depicted highest α-amylase and α-glucosidase enzyme inhibition with IC50 of 71.84 ± 1.06 and 57.25 ± 1.40 µg/mL, respectively. Molecular docking was performed to explore possible role of identified phytochemicals. Binding affinity data as well as interaction patterns have revealed possible interaction of the identified bioactives against α-glucosidase and α-amylase. Moreover, intra-molecular charge transfer, energies of the FMOs, HOMO-LUMO-Egaps, MEP and IP were also explained. The present findings suggested that, C. reflexa is a promising natural antioxidant and antidiabetic agent, thus supporting the use of this plant for designing related functional foods and nutra-pharmaceuticals.
