The antiemetic effect of aqueous and methanolic extracts of R. graveolens in young chicks was investigated. In addition, the phytochemical screening of the test plant and its acute toxicity studies were also conducted. Different doses of the extracts were tested for their antiemetic properties and were compared with the positive control antiemetic drug Chlorpromazine (150 mg/kg), Metoclopramide (50 mg/kg) and an untreated control (normal saline) against copper sulphate and Brassica-induced emesis. The phytochemical screening of R. graveolens showed that it contains certain alkaloids and flavonoids. It was found to be safe up to the dose of 2000 mg/kg body weight. The aqueous extracts in 50 and 150 mg/kg doses produced 41.49% and 66.49% inhibition of emesis, respectively by copper sulphate-induced emesis, while 34.66% and 57.95% inhibition of emesis, respectively by B. campestris-induced emesis. The methanolic extracts of Ruta graveolens in 50 and 150 mg/kg doses produced 46.80% and 70.20% inhibition of emesis, respectively by copper sulphate-induced emesis while 31.95% and 61.94%, respectively in Brassica campestris-induced chick emesis model. These results have suggested R. graveolens possess significant antiemetic properties that implicate its use as traditional medicine to treat emesis. However, further studies are needed to isolate the active principle(s) i.e. flavonoids contained in the plant drug tested and its real safety and efficacy as antiemetic agent.

Developing countries, where malaria is one of the most prevalent diseases, still rely on traditional medicine as a source for the treatment of this disease. For the present study,Trigonella foenum-graecumL. (fenugreek) were collected from Coimbatore, Tamilnadu, India. The test plant has been used in India by traditional healers for the treatment of fever as well as other diseases. The active principle was extracted out in different solvent systems to assess the anti-plasmodial potential, with an aim that they can further be utilized to formulate drugs.In vitroanti-plasmodial assay of the extracted fractions of fenugreek leaves was carried out using laboratory adapted chloroquine sensitive and resistantPlasmodium falciparumisolates. Schizont maturation inhibition assay was adopted to analyze the potential of the extracts. Ethanol extract (50%) seemed to possess profound anti-plasmodial activity with IC50value of 8.75 ± 0.35 µg ml−1and 10.25 ± 0.35 µg ml−1against chloroquine sensitive and resistantP. falciparumisolates, respectively. Among the investigated six fractions of the plant extracts, two were found to have significant anti-plasmodial activity with IC50values <10 µg ml−1, namely ethanol and butanol extracts. Two extracts chloroform and ethyl acetate showed moderate activity with IC50values ranging from 10 to 20 µg ml−1, and the other two extracts, hexane and water appeared to be inactive with IC50values >85 µg ml−1. In addition, preliminary phytochemical screening of the various extracts indicated the presence of alkaloids, saponin, tannin like phenolic compounds, flavonoids and steroids.

Abstract Background The banana or scientifically referred to as Musa sp., is one of the most popular fruits all over the world. Almost all parts of a banana tree, including the fruits, stem juice, and flowers are commonly used as traditional medicine for treating diarrhoea (unripe), menorrhagia, diabetes, dysentery, and antiulcerogenic, hypoglycemic, antilithic, hypolipidemic conditions, plus antioxidant actions, inflammation, pains and even snakebites. The study carried out was to evaluate in vitro anti-urolithiatic activity from different types of Musa pseudo-stems. Methods Observing anti-urolithiathic activity via in vitro nucleation and aggregation assay using a spectrophotometer followed by microscopic observation. A total of 12 methanolic extracts were tested to determine the potential extracts in anti-urolithiasis activities. Cystone was used as a positive control. Results The results manifested an inhibition of nucleation activity (0.11 ± 2.32% to 55.39 ± 1.01%) and an aggregation activity (4.34 ± 0.68% to 58.78 ± 1.81%) at 360 min of incubation time. The highest inhibition percentage in nucleation assay was obtained by the Musa acuminate x balbiciana Colla cv “Awak Legor” methanolic pseudo-stem extract (2D) which was 55.39 ± 1.01%at 60 min of incubation time compared to the cystone at 30.87 ± 0.74%. On the other hand,the Musa acuminate x balbiciana Colla cv “Awak Legor” methanolic bagasse extract (3D) had the highest inhibition percentage in the aggregation assay incubated at 360 min which was obtained at 58.78 ± 1.8%; 5.53% higher than the cystone (53.25%).The microscopic image showed a great reduction in the calcium oxalate (CaOx) crystals formation and the size of crystals in 2D and 3D extracts, respectively, as compared to negative control. Conclusions The results obtained from this study suggest that the extracts are potential sources of alternative medicine for kidney stones disease.

Pycnarrhena cauliflora (Miers.) Diels., local name sengkubak, is one of indigenous plants from West Kalimantan that has been used as natural flavor. Pycnorrhena cauliflora is one of species of Menispermaceae family which is rich in bisbenzylisoquinoline alkaloids. This alkaloids are known to have various biological activities including antiprotozoal, antiplasmodial, antifungal and antibacterial activities. This study aimed to investigate antimicrobial activity of  the P. cauliflora (Miers.) Diels. methanolic extracts against gram-positive and gram-negative bacteria. The methanolic extract of P. cauliflora (Miers.) Diels., root, leaf and stem were prepared by maceration. The disk-diffusion method was then used to determine the antimicrobial activity of the extracts against Streptococcus pyogenes, S. mutants, Staphylococcus aureus, S. epidermidis, Salmonella typhi, Shigella flexneri, Pseudomonas aeruginosa and Escherichia coli after 18-24 h incubation at 37 oC. Amoxicillin was used as positive control for gram-positive bacteria and ciprofloxacin was used as gram-negative bacteria. The inhibition zones were then measured in mm. Analysis were conducted in duplicates. The results showed in general the methanolic extracts of P. cauliflora (Miers.) Diels. root (inhibition zone diameter= 10-23 mm) were more active than that leaf (0-15 mm) and stem (0-17 mm) extracts against gram-positive bacteria. The zone inhibition diameter of amoxicillin as positive control was 8-42 mm. In addition, the methanolic extracts of P. cauliflora (Miers.) Diels. root (12-17 mm) were also more active than that leaf (0-12 mm) and stem (0-12 mm) extracts against gram-negative bacteria. The zone inhibition diameter of ciprofloxacin as positive control was 33-36 mm. In conclusion, the methanolic extract of P. caulifloria (Miers.) Diels. root is the most extract active against both gram-positive and gram-negative bacteria. Further study will be focused to isolate active compounds in the methanolic extract of the root.

Objective: Hyperlipidemia is one of the risk factors that contribute to the prevalence of coronary heart diseases and antihyperlipidemic agents, such as statin, was used to treat hyperlipidemia as a current therapy. Boesenbergia pandurata has not been exploited for antihyperlipidemic effect. Hence, this study aims to screen for the antihyperlipidemic activity of methanolic extracts of B. pandurata rhizomes (BPR extracts) in hypercholesterolemia-induced Sprague-Dawley rats.Methods: BPR extracts were prepared using the maceration method with 1500 ml of 80% methanol at room temperature for about 7 days. A toxicity study was carried out based on OECD guidelines. Hypercholesterolemia was induced by 6% lard oil, 2% of cheese, and egg yolks. Two different doses of BPR extracts, 200 and 400 mg/kg, were used to screen for antihyperlipidemic effect. Histopathological study was carried out in the liver. The results were evaluated for the statistically significant difference by using the one-way ANOVA followed by post hoc Dunnett test.Results: No mortality was witnessed even till 2 g/kg. Only 400 mg/kg of BPR extracts statistically reduced in total cholesterol (p<0.05), low-density lipoprotein-cholesterol (p<0.05) and an increase in high-density lipoprotein-cholesterol (p<0.05) when compared to the positive control. BPR extracts (400 mg/kg) showed less enlargement of lipid droplets as compared to positive control.Conclusion: BPR extracts can be a promising medicinal plant for treating hyperlipidemia in underdeveloped countries.

<em>The coffee leaf contains flavonoid compounds that are known as an antiinflammation agent. The study aimed to determine antiinflammatory activity of arabica coffee's leaf extract (</em>Coffea arabica<em> L.) against edema on white rat soles of carrageenan-induced rats. The research began with the maceration extraction of coffee leaf in 70% ethanol. The inflammation test was held by measuring the formation of edema using a plethysmometer. The dosages of arabica coffee leaf extract used were 60 mg.kg<sup>-1</sup>, 120 mg.kg<sup>-1</sup>, and 180 mg.kg<sup>-1</sup> rat weight of white Sprague Dawley rat (</em>Rattus norvegicus<em>). The data were analyzed by Kruskal Wallis and Mann Whitney non-parametric tests. Phytochemical screening showed that arabica coffee leaf extract contained flavonoid, saponin, alkaloid, tannin and triterpenoids compound. The arabica coffee leaf extract showed the best antiinflammatory activity at the dose of 180 mg.kg<sup>-1</sup> rat weight with 71.66% inhibition percentage at the 5<sup>th</sup> hour, which was better than the positive control (66.91% edema inhibition at the same hour). This result determined that the leaf extract of arabica coffee had antiinflammatory activity. However, it is necessary to study the acute and chronic toxicity and formulates the arabica coffee leaf extract as a pharmacy product.</em>
