Foods 2023; 12:4059. [PMID: 38002116 PMCID: PMC10670513 DOI: 10.3390/foods12224059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 11/01/2023] [Accepted: 11/06/2023] [Indexed: 11/26/2023] Open
Abstract
Cyperus rotundus L. exhibits promising potential for the development of functional foods due to its documented pharmacological and biological activities. This study investigated the antioxidant and anti-diabetic properties of C. rotundus kombucha. The results demonstrated potent antioxidant activity with an IC50 value of 76.7 ± 9.6 µL/mL for the DPPH assay and 314.2 ± 16.9 µL/mL for the ABTS assay. Additionally, the kombucha demonstrated alpha-glucosidase inhibitory with an IC50 value of 142.7 ± 5.2 µL/mL. This in vitro antioxidant potential was further validated in vivo using Drosophila. Drosophila fed a high-sugar diet and supplemented with pure kombucha revealed significant increases in DPPH and ABTS free radical scavenging activity. Drosophila on a high-sugar diet supplemented with varying kombucha concentrations manifested enhanced resistance to oxidative stresses induced by H2O2 and paraquat. Concurrently, there was a notable decline in lipid peroxidation levels. Additionally, significant upregulations in CAT, SOD1, and SOD2 activities were observed when the high-sugar diet was supplemented with kombucha. Furthermore, in vivo assessments using Drosophila demonstrated significant reductions in alpha-glucosidase activity when fed with kombucha (reduced by 34.04%, 13.79%, and 11.60% when treated with 100%, 40%, and 10% kombucha, respectively). A comprehensive GC-MS and HPLC analysis of C. rotundus kombucha detected the presence of antioxidative and anti-glucosidase compounds. In conclusion, C. rotundus kombucha exhibits considerable antioxidant and anti-diabetic properties, demonstrating its potential as a beneficial beverage for health promotion.

[PMID: 36658562 PMCID: PMC9850539 DOI: 10.1186/s12906-023-03839-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Accepted: 01/10/2023] [Indexed: 01/20/2023] Open
Abstract
BACKGROUND Trichinellosis, a zoonosis caused by the genus Trichinella, is a widespread foodborne disease. Albendazole, one of the benzimidazole derivatives, is used for treating human trichinellosis, but with limited efficacy in killing the encysted larvae and numerous adverse effects. Cyperus rotundus L. is a herbal plant with a wide range of medicinal uses, including antiparasitic, and is frequently used in traditional medicine to treat various illnesses. METHODS LC-ESI-MS was used to identify the active phytoconstituents in the methanol extract (MeOH ext.) of the aerial parts of C. rotundus and its derivate fractions ethyl acetate (EtOAc fr.), petroleum ether (pet-ether fr.), and normal butanol (n-BuOH fr.). The in vivo therapeutic effects of C. rotundus fractions of the extracts were evaluated using the fraction that showed the most promising effect after detecting their in vitro anti-Trichinella spiralis potential. RESULTS C. rotundus extracts are rich in different phytochemicals, and the LC-ESI-MS of the 90% methanol extract identified 26 phenolic compounds classified as phenolic acids, flavonoids, and organic acids. The in vitro studies showed that C. rotundus extracts had a lethal effect on T. spiralis adults, and the LC50 were 156.12 µg/ml, 294.67 µg/ml, 82.09 µg/ml, and 73.16 µg/ml in 90% MeOH ext., EtOAc fr., pet-ether fr. and n-BuOH fr., respectively. The n-BuOH fr. was shown to have the most promising effects in the in vitro studies, which was confirmed by scanning electron microscopy. The in vivo effects of n-BuOH fr. alone and in combination with albendazole using a mouse model were evaluated by counting adults in the small intestine and larvae in the muscles, in addition to the histopathological changes in the small intestine and the muscles. In the treated groups, there was a significant decrease in the number of adults and larvae compared to the control group. Histopathologically, treated groups showed a remarkable improvement in the small intestine and muscle changes. Remarkably, maximal therapeutic effects were detected in the combination therapy compared to each monotherapy. CONCLUSION Accordingly, C. rotundus extracts may have anti-T. spiralis potential, particularly when combined with albendazole, and they may be used as synergistic to anti-T. spiralis medication therapy.

Pharmacological studies of rhizomes of extract of Cyperus tegetum, emphasized on anticancer, anti-inflammatory and analgesic activity. JOURNAL OF ETHNOPHARMACOLOGY 2022; 289:115035. [PMID: 35085743 DOI: 10.1016/j.jep.2022.115035] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/24/2021] [Revised: 01/12/2022] [Accepted: 01/22/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE With over 950 species, Cyperus is one of the most promising health boosting genera in the Cyperaceae family. Traditional uses of Cyperus sp. have been described for gastrointestinal blood abnormalities, menstrual irregularities, and inflammatory diseases, among others. Cyperus tegetum Roxb belonging to Cyperaceae family, is used in traditional medicine to treat skin cancers. AIM OF THE STUDY The present study was carried out to explore the potential effect of the extract of the plant Cyperus tegetum against different pharmacological activity namely inflammatory, analgesic activity as well as skin cancer activity in mice. MATERIALS AND METHODS Cytotoxicity of the extract was measured by MTT and Live/death assay on HeLa cell line. Skin cancer was induced by 7,12-dimethylbenz(a) anthracene (DMBA) and 12-O-tetradecanoylphorbol-13-acetate (TPA) in mice to measure its effects. RESULT Stigmasterol and some poly phenolic compounds are identified using HPTLC process from the methanol extract of the rhizome of the plant Cyperus tegetum (CT-II). After confirmation of the presence of different polyphenolic compound and triterpenoids in the extract, it was subject to MTT and Live/death assay on HeLa cell line. From the observation it could be concluded that the IC50 of the extract is 300 μg/ml. Thus, the CTII was evaluated further for its in vivo anticancer property. In the tumorigenesis study, the number of tumor growths, the area and weight of the tumor significantly decreases with increment in the dose of CT-II extract and some elevated enzyme release in renal (creatinine, urea) as well as hepatic (AST, ALT, ALP) enzymes are also controlled with the increased dose of the same extract. The elevated enzyme release may be due to cancer induced rupture of the plasma and cellular damage. This CT-II extract also exhibits some other pharmacological activity like anti-inflammatory and analgesic activity. CONCLUSION As metabolic activation via carcinogens and inflammation response plays important role in development of cancer, antioxidant, anti-inflammatory and analgesic properties can be correlated with anti-cancer properties. Taken all the above studies, it was illustrated that the extract of Cyperus tegetum might be a promising compound to reduce skin cancer risk.

Abstract
Cyperus rotundus L. is widely used in Traditional Chinese Medicine and studies have reported its anticancer effect, but its chemical composition and therapy mechanism remains unknown. This research aims to analyze the chemical components of the ethanol extract of Cyperus rotundus L. (EECR), detect its treatment effects on human Triple-negative breast cancer (TNBC) cells, and elucidate possible therapy mechanisms. The chemical components of EECR were detected by the Waters UPLC combined with Bruker Q-TOF mass spectrometer (UPLC-Q-TOF-MS). The phytochemical compounds were identified by comparing the mass fragmentations of each metabolite with databases such as METLIN, HMDB, and NCBI. A total of 21 compounds were identified in EECR. MDA-MB-231 and MDA-MB-468 cells were treated with various concentrations of EECR. Cell proliferation was examined using Cell Counting Kit-8 (CCK-8) and colony formation assays. Cell apoptosis and cell cycle were detected by flow cytometry. Apoptosis- and autophagy-related protein expression was detected by Western blot. EECR inhibits the proliferation of TNBC cells (MDA-MB-231 and MDA-MB-468) in a dose-dependent manner, which may be related to the arrest of cell cycle in G0/G1 phase. It induces apoptosis by promoting the expression of BAX and inhibiting the expression of BCL-2. In addition, autophagy inhibitor 3-Methyladenine (3-MA) inhibited TNBC cells pro-survival autophagy and increased the sensitivity of EECR. The present results demonstrated that EECR has potential effects on inhibits the proliferation and induction apoptosis in TNBC.

Anti-mycobacterial activity of some medicinal plants used traditionally by tribes from Madhya Pradesh, India for treating tuberculosis related symptoms. JOURNAL OF ETHNOPHARMACOLOGY 2018; 227:113-120. [PMID: 30172059 DOI: 10.1016/j.jep.2018.08.031] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/25/2017] [Revised: 08/24/2018] [Accepted: 08/24/2018] [Indexed: 05/27/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tuberculosis (TB) is one of the highly infectious disease caused by the bacterium Mycobacterium tuberculosis (Mtb). Several medicinal plants are traditionally used by the tribal healers of some tribal pockets of Madhya Pradesh (M.P.), India in the treatment of various ailments including TB related symptoms. The information of traditional knowledge of plants is empirical lacking systematic scientific investigation. AIM OF THE STUDY To provide a scientific rationale for the traditional uses of some medicinal plants in treating prolonged cough, chest complaints and TB by ethnic groups in four districts of the state of M.P., India. The anti-mycobacterial activity of these plants was also investigated against multidrug-resistant (MDR) strains of Mtb. The active plant extracts were also assessed for general cytotoxicity by human monocytic leukemia cell line, THP-1 macrophages. MATERIALS AND METHODS Semi structured interviews and guided field-walk methods were used to gather information on medicinal plants used by the tribal traditional healers. The study was carried out in the tribal pockets of Anuppur, Mandla, Umariya and Dindori districts of M.P., India. A total of 35 plant species distributed in 22 families were selected based on folklore uses suggested by the tribal traditional healer. The ethanol extracts of plants were evaluated for anti-mycobacterial activity against Mtb H37Rv and six MDR clinical isolates of Mtb. The anti-mycobacterial activity of plants was determined in terms of minimum inhibitory concentration (MIC) using standard resazurin microtitre plate assay (REMA). The plant extracts found to be active against Mtb were further evaluated for general cytotoxicity against human THP-1 macrophages using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) assay. The selectivity index (SI) of active plant extracts were also calculated on the basis of MIC and cytotoxicity. RESULTS Out of the 35 plants, 11 plant species showed anti-mycobacterial activity with MIC ranging from 500 to 31.25 µg/mL against Mtb H37Rv. The plant extracts also exhibited anti-mycobacterial activity against six multi-drug resistant (MDR) clinical strains of Mtb isolated from sputum samples of pulmonary TB patients. In vitro cytotoxicity of active plant extracts was also assessed in human THP-1 macrophages. The IC50 (50% inhibitory concentration) values of most of the plant extracts on THP-1 was found to be higher than MIC values against Mtb, indicating that the THP-1 cells are not adversely affected at concentrations that are effective against Mtb. Significant anti-mycobacterial activity was observed for eleven plants viz., Alstonia scholaris (L.) R. Br., Glycyrrhiza glabra L., Holorrhena antidysentrica (Roth) Wall. exA.DC., Mallotus philippensis (Lam.) Müll. Arg., Eulophia nuda Lindl., Cocculus hirsutus (L.) Diels, Pueraria tuberosa (Willd.) DC., Cyperus rotundus L., Curcuma caesia Roxb., Sphaeranthus indicus L. and Plumbago zeylanica L. which lends support to their traditional uses. CONCLUSION The present investigation supports the potential role of plants used by tribal healers as our results have shown that these plants exhibit anti-mycobacterial activity in the acceptable range against Mtb. Our study clearly lends support to the traditional uses of some plants in TB related symptoms as we have found them to exhibit significant in vitro anti-TB activity. To the best of our knowledge, anti-mycobacterial activity in plants against Mtb is being reported for the first time from tribal areas of M.P., India by the current study.

Abstract
The nutgrass, Cyperus rotundus L. (Family: Cyperaceae), is a colonial, perennial herb considered to have originated in India 2000 years ago and widely used in Ayurveda to treat several ailments. In addition to its prehistoric uses, it is used in several systems of medicine for treating variety of diseases. The synergistic actions of the Cyperus' compounds have added advantage over that of a single constituent. In the past decade, numerous studies proved analgesic, anti-allergic, anti-arthritic, anti-candida, anti-cariogenic, anti-convulsant, anti-diarrheal, anti-emetic, anti-helminthic, anti-histamine, anti-hyperglycemic, anti-hypertensive, anti-inflammatory, anti-malarial, anti-obesity, antioxidant, anti-platelet, anti-pyretic, anti-ulcer, anti-viral, cardioprotective, cytoprotective, cytotoxic, gastroprotective, hepatoprotective, neuroprotective, ovicidal, and larvicidal, wound healing and inhibition of brain Na+ K+ ATPase activities of C. rotundus and its chemical constituents. However, the exact the mechanism of action is not very clear and requires further evaluation. These properties strongly suggest an extensive use of C. rotundus for clinical applications. In this review, we attempted to provide information about the pharmacological effects of Cyperus and its proposed mechanisms of actions.

Sequential extraction of C. rotundus rhizome with solvents of different polarity namely hexane, chloroform, ethyl acetate, methanol and water were prepared and the free radical scavenging activity was determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. Based on high antioxidant activity of methanolic extract of C. rotundus rhizome (MRCr) was further investigated for its cytotoxic effect on different human cancer cell lines-breast (MCF-7), cervical (HeLa), liver (Hep G2), prostate (PC-3), colorectal (HT-29) and normal cell line (MCF-12A) by 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT) assay evaluated as 50% inhibition of growth (IC50). Apoptosis cells were analysed by flow cytometry stained with annexin V-Fluorescein isothiocyanate conjugate (AF) and propidium iodide (PI). The cellular and nuclear changes were examined under light and fluorescent microscope using 4', 6' diamino-2-phenylindole (DAPI) stain, dual stains of AF/PI and acridine orange/ethidium bromide (AO/EB). The cytotoxic effects on the tested cancer cell lines ranged from 4.52±0.57 to 9.85±0.68μgml-1. The migration assay was showed the inhibitory effect with MRCr. The MRCr showed significant anticancer activity against all the tested cancer cell lines and also protected the non-cancer cells. The anticancer activity suggests further elucidation for the formulation of natural pharmaceutical products in the treatment of cancer.

Abstract
Diarrhea is a serious problem affecting 3-5 billion people per year around the world, especially children of below 5 years. 70% of the world population uses traditional and indigenous medicine for their primary health care. The facts of these indigenous remedies are passed verbally and sometimes as documents. Since ancient time, Ayurveda is the main system of healing in South East Asian countries. Indian literature from ayurvedic texts and other books claim the potency of several plants in the treatment of diarrhea. As the global prospective of ayurvedic medicine is increasing, interest regarding the scientific basis of their action is parallely increasing. Researchers are doing experiments to establish the relation between the claimed action and observed pharmacological activities. In the present article, an attempt was made to compile the scientific basis of medicinal plants used to cure diarrhea in Ayurveda. Literature was collected via electronic search (PubMed, ScienceDirect, Medline, and Google Scholar) from published articles that reports antidiarrheal activity of plants that were mentioned in Ayurveda classics. A total of 109 plant species belonging to 58 families were reported for their antidiarrheal activity. Several Indian medicinal plants have demonstrated promising antidiarrheal effects, but the studies on the antidiarrheal potentials of these plants are not taken beyond proof of concept stage. It is hoped that the article would stimulate future clinical studies because of the paucity of knowledge in this area.

Abstract
The Ayurvedic literature during the medieval period suggests the use of Musta (Cyperus rotundus), a common weed, as a pratinidhi dravya (substitute) for Ativisha (Aconitum heterophyllum), an endangered species. Contemporary Ayurvedic practice also uses Cryptocoryne spiralis, (known as Naattu Atividayam in South India) and Nagaramusta (Cyperus scariosus) as substitutes for Ativisha and Musta, respectively. This article reviews published literature on the pharmacology of the above four species. Both A. heterophyllum and C. rotundus are reported to possess antiinflammatory, antipyretic, antibacterial and antidiarrhoeal properties, while antiinflammatory and antibacterial activities are attributed to C. scariosus. No reports exist on the bioactivity of Cryptocoryne spiralis. It is interesting to note that other than the veerya which is different, the biological properties of Ativisha and Musta are similar according to Ayurvedic classification of dravyaguna. This is also supported by modern pharmacological studies, which show that, both A. heterophyllum and C. rotundus have antidiarrheal, antipyretic, antiinflammatory, antihyperlipidemic and hypoglycemic activities. However, the similarities between the discussed species cannot be attributed to their phytochemical composition or taxonomical classification as these are quite distinct. The dravyaguna method of classifying materials, which we are calling as “pharmaco-taxonomy”, offers a unique way of classifying those plant materials which lack similarity at the botanical or chemical level, but are similar at the level of biological functions.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In Ayurveda, the rhizome of Cyperus rotundus Linn has been reported for wide spectrum of biological activities including lactational therapy for increasing milk quantity. However, not a single report is available on validation of its herbal galactagogue potentiality in literature. Thus, the present study is aimed to assess the lactogenic property of aqueous extract of Cyperus rotundus (CRE). MATERIALS AND METHODS The effect of aqueous extract of Cyperus rotundus rhizome was evaluated by measuring weight of the pups during suckling period. Quantitatively, total protein and carbohydrate contents of mammary tissue and serum prolactin and cortisol level were calculated. Histopathological analysis of mammary gland, pituitary gland, heart, liver, spleen, kidney, and ovary tissues was carried out. Acute toxicity of CRE against rat was assessed by the Hippocratic test and biochemical profile of blood serum. RESULTS Oral administration of 300 and 600mg of CRE induced about 23% and 40% more milk in experimental group of animals as compared to the control group of animals. Weight gain by pups and mother rats of treated groups were significantly higher following administration of CRE as compared to that of control group. Moreover protein and carbohydrate content of mammary gland tissue were also significantly more than control group of animals. The CRE was found to stimulate the synthesis of prolactin significantly. In addition, the mammary gland tissues of experimental group showed obvious lobulo-alveolar development with milk secretion. Administration of CRE did not cause any signs or symptoms of toxicity which implied that Cyperus rotundus is toxicologically safe. CONCLUSION This study demonstrates that the aqueous extract of Cyperus rotundus can stimulate milk production in the female rats which may be consequently effective in increasing the lactation of human too.

Abstract
Background Cyperus rotundus Linn. (Cyperaceae) is used to treat inflammation, pain, fever, wounds, boils and blisters in folk medicine. This study evaluated the antinociceptive effect of the hydromethanol extract of whole plant of C. rotundus (HMCR). Methods The antinociceptive activity of HMCR was investigated in thermal-induced (hot plate and tail immersion) and chemical-induced (formalin) nociception models in mice at three different doses (50, 100 and 200 mg/kg; p.o.). Morphine sulphate (5 mg/kg, i.p.) and diclofenac sodium (10 mg/kg, i.p.) were used as reference analgesic agents. Results In the hot-plate and tail-immersion tests HMCR significantly increased the latency period to the thermal stimuli at all the tested doses (50, 100 and 200 mg/kg) (p < 0.05). The significant increase in latency is clear from the observations at 60 and 90 min. In formalin-induced paw licking test oral administration of HMCR at 100 and 200 mg/kg doses decreased the licking of paw in early phase. All the tested doses (50, 100 and 200 mg/kg) significantly decreased the licking of paw in late phase of the test (p < 0.001). The dose 200 mg/kg was most effective showing maximum percentage of inhibition of licking in both early (61.60%) and late phase (87.41%). Conclusion These results indicate the antinociceptive effect of C. rotundus and suggest that this effect is mediated by both peripheral and central mechanisms. These results support the traditional use of this plant in different painful conditions.

Abstract
BACKGROUND Topical Cyperus rotundus oil is an effective and safe method to decrease hair growth. The oil's flavonoids have antiandrogenic activity on androgenic hair. To date, there have been no randomized controlled trials comparing topical C rotundus oil to the available allopathic modalities, such as laser-assisted hair removal. OBJECTIVES In an open-label pilot study, the author prospectively evaluated the efficacy of C rotundus essential oil, compared with the Alexandrite laser (GentleLase; Candela Laser Corp, Wayland, Massachusetts) and saline, for reducing unwanted axillary hair. METHODS Eligible participants (n=65) with unwanted axillary hair were assigned randomly to 1 of 3 study groups: topical C rotundus oil (group 1), saline (group 2), and Alexandrite laser (group 3). Sixty patients completed the entire study. Three methods were used to evaluate the results: hair counts, observations of independent professionals, and patient self-assessments. RESULTS Overall results did not differ significantly between C rotundus oil and the Alexandrite laser (P>.05). However, statistically significant differences were noted with respect to decreased growth of white hair (P<.05), favoring the oil. This finding was evident by all 3 methods of assessment. No side effects were detected. CONCLUSIONS Cyperus rotundus essential oil is as effective as the Alexandrite laser for decreasing the growth of axillary hair (both dark and white). LEVEL OF EVIDENCE 3.

Abstract
Diarrhoeal diseases due to enterotoxigenic Escherichia coli continue to be a cause of global concern. Medicinal plants have been gaining popularity as promising antidiarrhoeal agents. In the present study, four antidiarrhoeal plants, viz. Aegle marmelos, Cyperus rotundus, Psidium guajava and Zingiber officinale were screened against a heat-stable toxin-producing enterotoxigenic E. coli strain. Decoctions of these plants were studied for their effect on intracellular killing of the bacterial strain using murine monocytic cell line, J774. [(3)H] thymidine release assay was used to evaluate the apoptotic/necrotic effect. All plants at concentrations <1% enhanced intracellular killing of the bacteria by J774 cells. However, at higher concentrations, the decoctions induced apoptosis in J774 cells. The study demonstrates that these plants could control diarrhoea caused by heat-stable toxin-producing enterotoxigenic E. coli through their immunomodulatory effect.

Abstract
PURPOSE To investigate the effects of three natural product compounds, carapin, santonin and isokobusone, on the activity of pregnane X receptor (PXR) and constitutive androstane receptor (CAR) in induction of drug-metabolizing enzymes and inhibition of inflammation. METHODS The monkey kidney-derived fibroblast (CV-1) cells and human embryonic kidney HEK293 cells were used for transient transfection and luciferase reporter gene assays. Human primary hepatocytes and primary hepatocytes from wild type, PXR-/-, and hPXR transgenic mice were used to study the induction of drug-metabolizing enzymes and the implication of these compounds in inflammation. RESULTS Carapin, santonin and isokobusone activated both PXR and CAR in transient transfection and luciferase reporter gene assays. Mutagenesis studies showed that two amino acid residues, Phe305 of the rodent PXR and Leu308 of the human PXR, are critical for the recognition of these compounds by PXR. Importantly, the activation of PXR and CAR by these compounds induced the expression of drug-metabolizing enzymes in primary human and mouse hepatocytes. Furthermore, activation of PXR by these compounds inhibited the expression of inflammatory mediators in response to lipopolysaccharide (LPS). The effects of these natural compounds on drug metabolism and inflammation were abolished in PXR-/- hepatocytes. CONCLUSIONS Our results show that carapin, santonin and isokobusone activate PXR and CAR and induce drug-metabolizing enzymes. In addition, these compounds inhibited the expression of inflammatory mediators in response to LPS through the activation of PXR.
