AbstractThe leaves of Piliostigma thonningii are used in traditional medicine in Benin to treat inflammatory skin diseases and infections. So far, pharmacological studies of the anti-inflammatory and anti-infective effects of phytochemically characterized extracts of P. thonningii have been very limited. Therefore, we investigated the in vitro anti-inflammatory and antimicrobial effect of P. thonningii leaf extracts and analyzed the phytochemical composition of extracts of different polarities (water, 50% ethanol, and n-hexane). Quercetin-3-O-rhamnoside was confirmed as the main flavonoid in the polar extracts. GC-MS analysis identified 20 constituents of the aqueous extract and 28 lipophilic compounds of the n-hexane extract by comparison with authentic standards and spectral library data. The aqueous P. thonningii leaf extract inhibited the IL-8 and IL-6 secretion in TNF-α-stimulated HaCaT cells in a concentration-dependent manner with IC50 values of 74 µg/mL for IL-8 and 89 µg/mL for IL-6. However, an inhibitory effect of the identified quercetin-3-O-rhamnoside and its aglycone, quercetin, on the release of IL-8 and IL-6 could not be demonstrated. In the antimicrobial screening, inhibition zones for a 50% EtOH leaf extract of P. thonningii were found for Staphylococcus epidermidis, Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, and Escherichia coli. For none of the microbial strains, however, the MIC was below 500 µg/mL, so that the antibacterial activity must be classified as low. As a result, our investigations primarily support the ethnomedical use of P. thonningii leaf extracts in topical inflammatory conditions. Further studies are required to identify the compounds responsible for the in vitro anti-inflammatory effects.

Objective: Plant-derived bioactive molecules are providing infinite opportunities for new drug development as they possess a wide range of actions against diseases with lesser side effects. The present study is made to analyze the qualitative phytochemicals and to evaluate in vitro antiproliferative and anti-inflammatory potentials of leaf extracts of Thespesia populnea. Methods: T. populnea leaf extracts were prepared sequentially according to the increasing polarity of the solvents, i.e., petroleum ether, chloroform, ethyl acetate, and methanol. Qualitative phytochemical analysis was performed to identify the chemical constituents of the extracts, and antiproliferative properties were evaluated against different cell lines using the 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide assay. Bovine serum albumin anti-denaturation assay was done to identify the anti-inflammatory activity.Results: Phytochemical analysis of the extracts revealed the presence of alkaloids, terpenoids, glycosides, tannins, flavonoids, and phenolics. The chloroform extract (CHFE) of T. populnea has a dose-dependent antiproliferative effect against acute T-cell leukemia (Jurkat E6-1), prostate Grade IV adenocarcinoma (PC-3), mouse fibroblast (L-929), and monkey kidney normal (Vero) cells. Their inhibitory concentration 50% (IC50) values were found to be 35.73±0.94 μg/ml for Jurkat E6-1, 60.79±1.84 μg/ml for PC-3, 60.88±1.45 μg/ml for L-929, and 83.482±2.05 μg/ml for Vero, respectively. CHFE also displayed the anti-inflammatory potential.Conclusion: The chloroform leaf extract of T. populnea possesses potent antiproliferative and anti-inflammatory activity. These properties present in leaf extract may be explained by the presence of biologically active constituents.

Background: Inflammation is emerging as a key contributor to many vascular diseases and furthermore plays a major role in autoimmune diseases, arthritis, allergic reactions, and cancer. Lipopolysaccharide (LPS), which is a component constituting the outer membrane of Gram-negative bacteria, is commonly used for an inflammatory stimuli to mimic inflammatory diseases. Nuclear factor-kappa B (NF-κB) is a transcription factor and regulates gene expression particularly related to the inflammatory process. Stauntonia hexaphylla (Lardizabalaceae) is widely used as a traditional herbal medicine for rheumatism and osteoporosis and as an analgesic, sedative, and diuretic in Korea, Japan, and China. Objective: The purpose of this study was to investigate the anti-inflammatory activity of YRA-1909, the leaf aqueous extract of Stauntonia hexaphylla using LPS-activated rat peritoneal macrophages and rodent inflammation models. Results: YRA-1909 inhibited the LPS-induced nitric oxide (NO) and proinflammatory cytokine production in rat peritoneal macrophages without causing cytotoxicity and reduced inducible NO synthase and prostaglandin E2 levels without affecting the cyclooxygenase-2 expression. YRA-1909 also prevented the LPS-stimulated Akt and NF-κB phosphorylation and reduced the carrageenan-induced hind paw edema, xylene-induced ear edema, acetic acid-induced vascular permeation, and cotton pellet-induced granuloma formation in a dose-dependent manner in mice and rats. Conclusions: S. hexaphylla leaf extract YRA-1909 had anti-inflammatory activity in vitro and in vivo that involves modulation of Akt/NF-κB signaling. Thus, YRA-1909 is safe and effective for the treatment of inflammation.

Garcinia mangostana L. is medicinal plant. Its fruit, the mangosteen contains many bioactive xanthones. This study investigates the potential of organic leaf extracts of G. mangostana grown in Ivory Coast. We tested two organic leaf extracts: G. mangostana aqueous ethanolic leaf extract (ethanol: water, 80:20 v/v) (GMLE) and dichloromethane leaf extract (GMLD). We measured total phenolic and total Flavonoids. We analysed the in vitro anti-inflammatory, anti-radical and anti-proliferative activities of leaf extracts. Ethanol leaf extract showed a considerable amount of phenolic content (328.78±34.32 mg GAE/g) and moderate flavonoids content (43.60±1.48 mg QE/g), Dichloromethane extract had low values of phenolic (70.31±4.55 mg GAE/g) and flavonoids (8.49±0.69 mg QE/g). However, GMLD extract gave a significant anti-inflammatory activity (IC50=152.79±3.34 µg/mL), comparable to the standard drug diclofenac sodium (IC50=142.30±1.22 µg/mL), contrary to GMLE extract (IC50=652.33±12.23 µg/mL). The radical scavenging assay showed a very significant ability of ethanol leaf extract to reduce the DPPH radical (IC50=33.40±0.67 µg/mL) compared to references molecules such as Trolox (IC50=43.72±0.31 µg/mL) and acid ascorbic (IC50=27.20±0.17 µg/mL), dichloromethane extract results showed lowest activity (IC50 = 580.00±23.03 µg/mL). All the organic leaf extracts of G. mangostana had moderate anti-proliferative activity on L20B, RD and VS cell lines studied with IC50 values ranging from 110.89 ±4.82 µg/mL to 860.60±25.78 µg/mL). Our results prove the high potential of the G. mangostana leave extracts as anti-inflammatory and anti-oxidative stress drugs. However, further studies are to determine and validate all the medicinal properties of G. mangostana leaves extracts.

Aim: This work was aimed at investigating the phytochemical, proximate, anti malarial, anti inflammatory, anti bacterial and anti fungal activities of leaf extracts of Combretum platypterum. Methods: Leaves of C. platypterum were cold extracted with methanol, ethyl acetate and n-hexane. The extracts were subjected to preliminary phytochemical analyses, proximate, anti malarial, anti inflammatory and antimicrobial tests. Results: The results revealed that, alkaloids, terpenoids, flavonoids, cardiac glycosides, carbohydrates, resins and reducing sugars were found in all the extracts. It was also observed that the presence of the metabolites in each extract was in polarity-dependent manner. The percentage composition of carbohydrates was also the highest followed by the composition of proteins. The suppressions of the extracts against P. falciparum at half-maximal inhibitory concentration (IC50 mg/ml) were found to be higher than that of chloroquine at IC50 µg/ml. It was also found that methanol extract had the highest inhibition against Gram positive, Gram negative bacteria and C. albicans in a dose-dependent manner. K. pneumonia was resistant to the inhibition of the extracts. The anti inflammatory assays showed that methanol extracts at 500 mg/ml exhibited higher lipoxygenase Inhibition than diclofenac at 500 µg/ml. Ethyl acetate extract showed highest inhibition of heat-induced hemolysis, protein denaturation and proteinase among all the extracts. Conclusion: The therapeutic use of the leaves of C. platypterum against malaria and swelling was confirmed by the activities of the extracts against inflammation and P. falciparum. It is also necessary that the bioactive compounds responsible for these activities be isolated.

Abstract Mulberry leaves are widely used in traditional Chinese medicine for their antioxidant, anti-inflammatory, antibacterial, antiobesity, antidiabetic, antiatherosclerotic, and anticancer properties. The current study aimed to investigate the effect of mulberry leaf extract (MLE) on Staphylococcus aureus (S. aureus)-induced conjunctivitis (5 × 109 CFU, 0.5 mL/eye) in a rabbit model. Rabbits were treated with MLE (5 mL/kg·d-1 and 10 mL/kg·d-1), 0.9% saline, or pearl bright eye drops (PBE) for 5 days. The results showed that MLE treatment significantly reduced the clinical sign scores of conjunctivitis, alleviated clinical signs, and decreased bacterial load and histological damage in a time- and dose-dependent manner compared to that in the conjunctivitis control group. The antibacterial and anti-inflammatory activities of MLE (10 mL/kg·d-1) were equal to or greater than those of the positive control drug PBE. In addition, MLE significantly decreased the levels of pro-inflammatory cytokines, downregulated the NOD-like receptor leucine-rich pyrin domain-containing protein 3 (NLRP3) inflammasome, and upregulated the nuclear factor erythroid 2-related factor 2 (Nrf2) system. Overall, MLE is effective in alleviating S. aureus-induced conjunctivitis in rabbits and this mechanism is associated with the inhibition of the NLRP3 inflammasome and activation of the Nrf2 system to regulate pro-inflammatory signaling.
