The present investigation was aimed to study the antidiabetic, antihyperlipidemic, andin vivoantioxidant properties of the root ofSphaeranthus indicusLinn. in streptozotocin- (STZ-) induced type 1 diabetic rats. Administration of ethanolic extract ofSphaeranthus indicusroot (EESIR) 100 and 200 mg/kg to the STZ-induced diabetic rats showed significant () reduction in blood glucose and increase in body weight compared to diabetic control rats. Both the doses of EESIR-treated diabetic rats showed significant () alteration in elevated lipid profile levels than diabetic control rats. The EESIR treatment in diabetic rats produced significant increase in superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and decrease in thiobarbituric acid reactive substances (TBARS) levels than diabetic control rats. Administration of EESIR 200 mg/kg produced significant () higher antioxidant activity than EESIR 100 mg/kg. The high performance liquid chromatography (HPLC) analysis of EESIR revealed the presence of biomarkers gallic acid and quercetin. In conclusion, EESIR possess antidiabetic, antihyperlipidemic, andin vivoantioxidant activity in type 1 diabetic rats. Its antioxidant and lipid lowering effect will help to prevent diabetic complications, and these actions are possibly due to presence of above biomarkers.

Diabetes mellitus has been treated orally with herbal remedies based on folk medicine since ancient times.Embelia ribes burm(Myrsinaceae), known commonly as vidanga, was used in Ayurveda for its anthelmintic activity. Ayurveda describes vidanga as pungent, causes increase in digestive fire, and cures flatulence and colic. A single study reported the antihyperglycemic activity of decoction ofE. ribesin glucose-induced hyperglycemic albino rabbits. In the present study, the lipid-lowering and antioxidant potential of ethanolic extract ofE. ribes burmwas investigated in streptozotocin (40 mg/kg, IV, single injection)-induced diabetes in rats. Twenty days of orally feeding the extract (200 mg/kg) to diabetic rats resulted in significant (P< 0.01) decrease in blood glucose, serum total cholesterol, and triglycerides, and increase in HDLcholesterol levels when compared to pathogenic diabetic rats. Further, the extract also lowered the liver and pancreas thiobarbituric acid–reactive substances (TBARSs) values (P< 0.01) when compared to TBARS values of liver and pancreas of pathogenic diabetic rats. The results of test drug were comparable to gliclazide (25 mg/kg, orally), a standard antihyperglycemic agent. This is the first pilot study to provide biochemical evidence of potential ofE. ribesin diabetic dyslipidemia.

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.

The antidiabetic, normolipidaemic, antioxidant and safety evaluations of ethanolic extract of Acacia ataxacantha roots (EEAAR) were investigated in streptozotocin - induced diabetic rats, to verify its use in traditional African medicine and as alternative to synthetic normoglycaemic agents in diabetic treatments. Thirty albino rats (Rattus novergicus) were randomized into six groups - control, diabetic control, EEAAR-treated at 125 mg/kg, 250 mg/kg, 500 mg/kg body weights (b.wts.) and metformin groups, respectively. Phytochemical screening showed the presence of alkaloids, polyphenols, flavonoid, saponins, tannins and terpenoid. Blood glucose was significantly reduced (p < 0.05) especially after 7 days of oral administration of EEAAR at 125 mg/kg b.wt with values (110.01 ± 9.64 mg/dl) similar to that of the control (106.33 ± 4.13 mg/dl). There was an increase (p < 0.05) in the ALT and AST activities of the liver and serum of rats in all the groups except in those that received 125 mg/kg b.wt. Serum total cholesterol, low density lipoprotein cholesterol and triglyceride were decreased (p < 0.05) upon administration of the extract and metformin. There was no difference (p > 0.05) in malondialdehyde concentration of rats administered with 125 mg/kg b.wt. of extract and metformin. Superoxide dismutase activity was elevated (p < 0.05) in all groups and compared favourably with the control in each of the tissues. This study revealed the antidiabetic and hypolipidaemic effects of EEAAR, which may be due to the antioxidant properties of some of the phytochemical constituents. However, the extract may not be safe at large and repeated doses.

Objectives: Antioxidant is a substance such as Vitamin C that able to remove potentially damaging oxidizing agents. Malondialdehyde (MDA) is an important marker of oxidative stress that have correlation with Type 2 diabetes mellitus (DM) progression. Phaseolus vulgaris L (PV) (beans) is one of the alternative medicines to treat DM in Indonesia. We investigated the antioxidant activity of ethanolic extract on PV (EEPV) beans using in vitro and in vivo model.Methods: Antioxidant assay in vitro was conducted using 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. Alloxan (120 mg/kg, intraperitoneally)- induced diabetic rats were divided into 5 groups (n=5), i.e., NC: Normal control, P1: Diabetic-control, P2, P3, and P4 (200 mg/kg, 400 mg/kg, and 600 mg/kg of EEPV, orally) for 28 days. MDA serum level was evaluated using spectrophotometer. The data were analyzed by one-way ANOVA test.Results: The antioxidant assay in vitro showed that EEPV has very weak (IC50=641.87 μg/ml, whereas Vitamin C as standard showed very strong activity (IC50=2.95 μg/ml). MDA level were 2.80±0.09 nmol/ml (NC), 3.30±0.42 nmol/ml (P1), 3.27±4.23 nmol/ml (P2), 2.93±0.05 nmol/ml (P3), and 3.17±0.25 nmol/ml (P4). There was no significant differences among normal control, diabetic-control, and EEPV-treated groups (p>0.05).Conclusion: EEPV showed a very weak antioxidant activity in vitro.

Objective: This study was aimed to evaluate the antioxidant potential of sinapic acid in both in vitro and in vivo. Recently, we have reported that oral administration of sinapic acid (3,5-dimethoxy 4-hydroxycinnamic acid) an active phyto ingredient widely distributed in rye, mustard, berries, and vegetables has been shown to ameliorate hyperglycemia.Methods: Experimental Type 2 diabetes was induced in male Wistar rats by feeding high-fat diet to induce insulin resistance followed by intraperitoneal administration of a single low dose streptozotocin (35 mg/kg body weight [bw]). Sinapic acid was administered orally at a concentration of 25 mg/kg bw/rat/day for 30 days, and its efficacy was compared with metformin. In vitro, antioxidant scavenging properties of sinapic acid were determined using 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS), superoxide, and nitric oxide (NO) assay.Results: Sinapic acid treatment showed a significant decline in the levels of lipid peroxides, hydroperoxides and protein carbonyls in the plasma and vital tissues of diabetic rats. The treatment also improved the antioxidant status in diabetic rats indicating the antioxidant potential of sinapic acid. In addition, the results of DPPH, ABTS, superoxide, and NO radical scavenging assays substantiate the free radical scavenging efficacy of sinapic acid.Conclusion: The results of this study evidenced that sinapic acid possess significant antioxidant properties which in turn may be responsible for its antidiabetic properties.

Metabolic diseases have increased considerably such as diabetes mellitus (DM). Since diabetes is a systemic disease, it implies high cardiovascular risks. It has been widely established that cardiac injury is related to mitochondrial dysfunction through increment of reactive oxygen species (ROS). Synthetic antioxidants can have important side effects; therefore natural sources may represent a better option. Traditional Mexican medicine has been using Eryngium carlinae (EC) for medical treatment. Also our group showed that hexanic extract possesses in vitro antioxidant capacity. Experimental diabetes in Wistar rats was generated by streptozotocin (STZ) and hexanic extract of EC was supplied for 7 weeks (30 mg/kg). Cholesterol, triacylglycerides, glucose, and thiobarbituric acid reactive substances (TBARS) levels were determined in serum. Mitochondria from left ventricle were used in the quantification of TBARS, reduced glutathione, nitric oxide (NO) levels and activity of superoxide dismutase (SOD) enzyme was performed.  Biochemical parameters of glucose and triacylglycerides, as well as TBARS levels in serum show a significant reduction in diabetic group supplied with EC hexanic extract. Thus, we can conclude that the EC hexanic extract possesses antioxidant activity in vitro, and in vivo, by reducing glucose and triacylglycerides levels during hyperglycemia, which may eventually reduce the risk of developing diabetic cardiomyopathy.

Abstract Incidence of various dreadful microbial infections and the development of antibiotic resistance by infection causative microbes are the main reasons for reducing aquaculture productivity. Hence, there is an immense need for the discovery of alternative and efficient treatment for quick recovery of diseased fishes. In the present study, Suaeda maritima leaf extracts (hexane, diethyl ether, ethanol, and water) were screened for in vitro and in vivo antibacterial and antioxidant activities. Out of all the four extracts, ethanolic extract showed highest antibacterial activity against S.aureus (4.9±1.3 mm), B.subtilis (1.6±0.3 mm), K.pneumonia (4.2±1.8 mm), and P.aeruginosa (4.1±1.2 mm). Similarly, antioxidant activity was also higher for ethanolic extract (500 µg/ml) based on DPPH radical scavenging ability (71.6±1.4 %) and reducing potential (149 μg/mL) assays. Further, ethanolic extract was purified consecutively via column chromatography and preparative TLC where an active fraction was selected based on highest antibacterial (10.1±1.4 mm) and antioxidant properties (82.3±2.8 %). Active fraction was loaded onto mass spectroscopy and identified the presence of four active constituents such as 1,2,9,10-tetramethoxy-6-methyl-5,6,6a,7-tetrahydro-4H-dibenzo[de,g]quinolin-3-yl) methanol; 3',7-Dimethoxy-3-hydroxyflavone; Saponin and (19R)9acetyl19hydroxy10,14dimethyl20oxopentacyclo[11.8.0.0<2,10>.0<4,9>.0<14,19>]henicos-17-yl-acetate. Besides, in vivo studies were conducted on Catla catla fingerlings infected with P. aeruginosa under laboratory conditions. The fingerlings were segregated into 5 groups, among which group 4 and 5 were treated with crude and purified extracts. Both the extracts were efficient in treating infected fingerlings and recorded 100% survival rate which is even better than group-3 treated with a synthetic antibiotic (77%). Hence, S. maritima leaf extract can be considered as a possible alternative medicine in aquaculture
