Abstract. Miftahudin, Hasibuan RS, Chikmawati T. 2019. Antioxidant activity of ethanolic extract of three Selaginella species from Java Island, Indonesia. Biodiversitas 20: 3715-3722. Three Selaginella species, S. ornata, S. plana, and S. willdenowii, from Java Island, Indonesia, have been known to have antioxidant properties; however, in vivo antioxidant activities of these species have not been reported. This research aimed to evaluate the in vivo antioxidant activity of ethanolic extract of three Selaginella species. The 70% ethanol extract of three Selaginella species at four different doses was administered to mice one day before being treated with oxidative stress. The liver tissue of mice treated with or without oxidative stress was analyzed their lipid peroxidation by measuring MDA concentration and Superoxide Dismutase (SOD) activities. The results showed that there were variations in antioxidant activity among the three Selaginella species. In general, the dose of 0.3 g extract kg-1 BW has been able to reduce lipid peroxidation and increase SOD activity. The administration of S. ornata extract to the mice at 1.2 g extract kg-1 BW reduced the MDA concentration to the lowest level, but the same dose of two other Selaginella extracts caused toxic effects in mice. The antioxidant activities of S. ornata and S. plana were better than that of S. willdenowii extract, and among those species, S. ornata has the best antioxidant activity.

Wedelia chinensis is a widely used anti-inflammatory and hepatoprotective medicinal plant in Bangladesh. In this study, analgesic, neurological, antioxidant and cytotoxic activities of the ethanolic extract of leaf and stem bark of W. chinensis were investigated. Oral administration of the ethanolic extract of W. chinensis (200- and 300-mg/kg body weight) was investigated on animal model for neurological activity using open field test and hole cross test. Acetic acid induced writhing method was used to assess the analgesic activity. DPPH (1,1-diphenyl, 2-picryl hydrazyl) radical scavenging assay was used for determining the antioxidant activity, while brine shrimp lethality bioassay was used for investigating cytotoxicity. The ethanol extract of the plant produced significant reduction (P<0.05) of locomotion in both doses (200- and 300-mg/kg body weight) indicating pronounced neurological activity. Oral administration of alcoholic leaves and stem extracts significantly (p < 0.05) inhibited writhing response in mice. The percentage of scavenging of DPPH free radical was found to be concentration dependent with IC50 value of 44.10 ± 0.65 and 38.96 ± 0.50 μg/ml for leaves and stem extracts, respectively. Our findings indicate that W. chinensis may be a source of natural antioxidant with potent analgesic, neurological and cytotoxic activities. Bangladesh Pharmaceutical Journal 22(1): 18-26, 2019

Leaves from Eugenia uniflora, the red Brazilian cherry, have a high content of flavonoids that possess several biological effects such as anti-inflammatory, antioxidant, and antidiabetic activities. However, their influence on carbon tetrachloride (CCl4)-induced acute liver injury in rats has not been investigated. In the current study, a bioguided fractionation assay revealed that the ethyl acetate fraction (EAF) of Eugenia uniflora is the safest and most active fraction. LC-MS analysis of the ethyl acetate fraction revealed 22 secondary metabolites, mainly myricetin and quercetin derivatives. EAF did not show toxicity up to 2000 mg/kg, and exhibited antioxidant activities in vitro in DPPH assay with IC50 of 3.35 µg/mL. Additionally, EAF exhibited substantial antioxidant activities in vivo by counteracting the oxidative damage of the prooxidant juglone [80 µM] in Caenorhabditis elegans model organism and increased its survival rate in a dose-dependent fashion through the DAF-16/Foxo pathway. Furthermore, the hepatoprotective activity of EAF (200 mg/kg against carbon tetrachloride (CCl4) intoxicated male Wistar rats was assessed. EAF significantly inhibited CCl4-induced elevation of alanine aminotransferase (ALT), aspartate transaminase (AST), total bilirubin (TB), total cholesterol (TC), and triglycerides (TG), in the blood serum and prevented lipid peroxidation and restored superoxide dismutase (SOD) activity and glutathione (GSH) content in liver tissues. The observed hepatoprotective effects of EAF, which were supported by histopathological observations as pretreatment with EAF, effectively attenuated the CCl4-induced histopathological changes. In conclusion, EAF of Eugenia uniflora leaves has substantial hepatoprotective activities against CCl4 induced acute liver injury in rats due to its antioxidant activity.

Abstract Background Sophora exigua Craib. is commonly used in Thailand to reduce fever and increase postpartum breast milk production in women who have hypogalactia. However, there has been no report on the antioxidant and antimalarial properties of this plant. This study aimed to investigate the antioxidant and antimalarial activities of S. exigua root extract and to evaluate its acute toxicity in mice to confirm its safety. Methods The in vitro antioxidant activities were determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), superoxide radical, and hydroxyl radical scavenging assays. The in vivo antioxidant activities were determined by detecting the malondialdehyde (MDA) content and superoxide dismutase (SOD) activity in the livers of malaria-infected mice. The in vivo antimalarial activity was determined by Peters’ 4-day suppressive test in mice infected with Plasmodium berghei ANKA and orally administered S. exigua root aqueous and ethanolic extracts at different doses (200, 400, and 600 mg/kg body weight). In addition, the acute oral toxicity of the plant extracts was assessed in mice at a dose of 2000 mg/kg body weight. Results The ethanolic extract of S. exigua root exhibited inhibition of DPPH radicals, superoxide anions, and hydroxyl radicals, with half maximal inhibitory concentration (IC50) values of 24.63 ± 1.78, 129.78 ± 0.65, and 30.58 ± 1.19 μg/ml, respectively. Similarly, research on the in vivo antioxidant activity indicated that the ethanolic extract of S. exigua root exerted a stronger effect than the aqueous extract. The aqueous extract at doses of 200, 400, and 600 mg/kg had stronger antimalarial activity than the ethanolic extract. The aqueous extract at 600 mg/kg exhibited 60.46% suppression of parasitemia. Increased levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) and blood urea nitrogen (BUN) were detected in the mice treated with 2000 mg/kg ethanolic extract, which was related to the results of histopathological analysis of liver tissue, showing ballooning degeneration of hepatocytes, diffuse hepatic hemorrhage, and infiltration of inflammatory cells. Conclusions This study demonstrated that the ethanolic S. exigua root extract possessed antioxidant properties, and the aqueous extract also had antimalarial activity. Therefore, this plant is an alternative source of new antioxidant and antimalarial agents.

Sexual dysfunction is a widely found disorder worldwide now a day because of busy lifestyle and stress. Management of disease is somewhat difficult because of cost and shortage of effective treatment. In the present paper authors have investigated effect of ethanolic extract of Flueggea leucopyrus Willd. leaves as aphrodisiac potential on albino rats. The dried leaves of plant were extracted by cold maceration method using ethanol. It was investigated for in vivo aphrodisiac activity. Plant extract was administered at doses 200 and 400 mg/kg body weight for 45 days. The effect of extract on general mating behavior, potency test, morphological studies, organ weight and sperm motility were tested. The results were compared with standard reference sildenafil citrate. The acute toxicity of the drug extract was also checked. On oral administration of ethanol extract 200 and 400 mg/kg doses on 15th, 30th and 45th day of treatment in all treated groups significantly increased intromission latency, mounting frequency, ejaculatory latency and significantly decreased intromission latency, mounting latency, inter intromission interval and post ejaculatory interval. Test for potency showed significant increase in long flips, quick flips and erections. In all experimental animals morphological study showed significant increase in main and accessory reproductive organs weight and sperm motility. As compared to the control the prolonged treatments for all treated groups were highly effective. This showed that aphrodisiac activity has been shown by ethanol extract but it is less than the standard. The present study showed that ethanol extract of Flueggea leucopyrus Willd. leaf increase sexual behavior in rats. Thus it supports the claim for this drug as an aphrodisiac

Rat hepatocyte monolayer culture and wistar albino rats were exercised as in vitro and in vivo screening models of protective agent for liver. In in vitro analyses, the whole plant ethanolic extract of Indigofera tirunelvelica Sanjappa were inspected. Silymarin was chosen as a standard treatement drug. In vitro, free radical scavenging property was also evaluated. In animal studies, hepatotoxicity was produced in Wistar albino rats by dispensing CCl4. The degree of hepatotoxicity was examined by determining the ranges of serum enzyme. The antioxidant parameters such as superoxide dismutase, catalase, reduced glutathione, and malondialdehyde of the hepatocytes were also evaluated. In in vitro studies, ethanol extract of I. tirunelvelica whole plant was identified to be the most active than other assessed extracts. Besides, whole plant ethanol extract of I. tirunelvelica was noticed to be rich in phenolic and flavonoids. It exhibited expressive free radical scavenging property versus diphenylpicryl hydrazyl (DPPH) and superoxide ion radicals. In the animals studies, whole plant ethanolic extract of I. tirunelvelica at a ranges of doses (100, 200 and 400 mg/kg body weight) revealed considerable amount of protection against CCl4 induced hepatotoxicity as evident by the protection of CCl4 induced changes biochemical parameters. The results of the present study suggested that the significant hepatoprotective property of whole plant ethanol extract of I. tirunelvelica against CCl4 induced hepatotoxicity and intimates its use as a potential medicinal drug for liver diseases.

National data shows the prevalence of coronary heart disease is 3,6%. The prevalence of dyslipidemia is around 35,9%. Dyslipidemia has a causal relationship with cardiovascular disease. Based on previous research, 70% ethanolic extract of Ridge Gourd has been shown to have antihyperlipidemic activity. This study aimed to study the activity of 70% ethanolic extract fraction of Ridge Gourd in decreasing the levels of total cholesterol, low-density lipoprotein (LDL-C), and triglycerides in hyperlipidemic hamsters. A total of 32 hamster were divided into 8 groups. Negative control, normal control, positive control (using atorvastatin dose 1,24 mg/kg body weight), positive control (fenofibrate dose 12,35 mg/kg body weight), ethyl acetate fraction, n-hexane fraction, water fraction (fraction doses 36,75 mg/kg body weight), and ethanol extract group (extract dose of 240 mg/kg body weight). The results showed that fraction group (n-hexane, ethyl acetate, water) and ethanol extract group experienced a decrease in total cholesterol, LDL-C, and triglycerides levels. Statistical analysis with one-way ANOVA showed an effect on the treatment given (p = 0,005). Tukey's test showed that ethyl acetate fraction group had an effect comparable to positive control with a decrease in total cholesterol,  LDL-C, and triglycerides level by 56,03%, 52,14%, and 59,51% consecutively. Ethyl acetate fraction (doses 36,75 mg/kg body weight) was the most effective fraction in reducing total cholesterol, LDL-C, and triglycerides.

Ingestion of arsenic, a known contaminant in drinking water causes cancer at multiple tissues and there is no cure. Consumption of arsenic contaminated water has been implicated metalloid-induced carcinogenesis. Research is therefore directed at chemoprevention using medicinal herbs for the management of arsenicosis. In this study hepatoprotective activity of ethanolic extract of Annona muricata (AM) leaves was assessed against sodium arsenite (SA) induced hepatic injury in albino rats. The animals were pre-treated with either 250 or 500mg/kg body weight of rat before exposure to SA. SA was dissolved in distilled water and administered at a dose of 5 mg/kg body weight on the 7th, 14th and 21st day of the experiment. SA was observed to induce a significant increase (p < 0.05) in serum aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatase activities (ALP). However, pretreatments of rats with various doses of AM significantly (P<0.005) reduced serum enzyme levels to near normal against SA treated rats. Furthermore, histopathological observations revealed that treatment with AM extract protected the animals from SA induced liver damage. The results indicated that the leaves of Annona muricata possess hepatoprotective activity on SA induced hepatic injury in rats.

In this study, the in vivo antioxidant potentials of Piliostigma thonningii were investigated in carbon tetrachloride-induced hepatic and oxidative damage in rat. Albino rats were grouped into six, group A rats received sterile distilled water for 14 days while B rats received 0.5 mL/kg body weight of carbon tetrachloride intraperitoneally on day 14. Group C rats received 200 mg/kg body weight of Piliostigma thonningii leaves extract for 14 days. Groups D, E and F rats were pretreated with 50, 100 and 200 mg/kg body weight of Piliostigma thonningii leaves for 14 days and challenged with 0.5 mL/kg body weight of carbon tetrachloride on day 14. The extract treatment significantly attenuated both the decrease and the increase in liver and serum marker enzyme. Antioxidant enzyme activity as well as level of uridyl diphosphoglucuronosyl transferase, quinone oxidoreductase and glutathione S-transferase was significantly induced. There was attenuation of malonidialdehyde and lipid hydroperoxide increase. On the basis of the available data in this report, it can be postulated that Piliostigma thonningii leaves protect liver against hepatic and oxidative damage by carbon tetrachloride possibly by acting as an in vivo free radical scavenger, induction of antioxidant enzymes, drug detoxifying enzymes and prevention of excessive stimulation of antioxidant enzyme and lipid peroxidation.

Abstract Background Garcinia lanceifolia Roxb. has been used by many ethnic communities of Northeast India to mitigate various disorders like dyspepsia, ulcers, diabetes, etc. However, a robust scientific study on its antidiabetic and antiulcer potential is unavailable till date. The aim of this present study is to scientifically validate if the antidiabetic and antiulcer effects reported by the ethnic tribes of Assam has any scientific value or not. The effects were tested in adult Wistar albino rats using approved animal models for preclinical testing of pharmacological activities. Results The hydroalcoholic extract of the bark of Garcinia lanceifolia Roxb. was prepared and its LD50 was calculated. The LD50 was determined to be greater than 5000 mg/kg body weight. The extract at doses of 250 mg/kg body weight and 500 mg/kg body weight was found to exhibit a very potent dose-dependent antidiabetic activity. The results were backed by a battery of test including analysis of serum levels of blood glucose, lipid profiles, in vivo antioxidant enzymes, and histopathological studies. Evidence of dose-dependent antiulcer activity of the extract was backed by robust scientific data. It was found that HAEGL induced a significant dose-dependent increase in the ulcer index in both alcohol-induced and acetic acid-induced ulcer models, which was evident from the macroscopic observation of the inner lining of the gastric mucosa and the histological evaluation of the extracted stomach. Conclusion The results suggested that the bark of Garcinia lanceifolia (Roxb.) has significant antidiabetic and antiulcer potential. Further studies with respect to the development herbal dosage forms and its safety evaluation are required.
