Abstract

Eupatorium riparium Reg. is one of medicinal plant that might be used to cure a disease optimally. Some research reports and traditional uses in society show that this plant can  be used as a diuretic, anti-inflammatory, hepatoprotective, immunostimulant, anti-malarial, and anti-infective agents. Therefore, it is necessary to evaluate its safety. The aim of this study is to determine the acute toxicity of the aqueous extract of E. riparium Reg. at Sprague-Dawley (SD) rats. The acute toxicity test was conducted using the method of OECD 423. Male SD rats were orally given aqueous extracts of E. riparium Reg. which was started with a dose of 2000 mg / kg. Observations were performed 24 hours after the administration with intensive observations on the first 4 hours. The result showed that there were no animals found in dead condition when treated with a dose of 2000 mg/kg; repeated testing is also showed that no animals died, so the observation was continued until 14 days. The dose was increased to 5000 mg/kg, and again there were no dead animals. From the results, it can be concluded that the potential for acute toxicity (LD50) (cut off) of aqueous extract of E. riparium Reg., in rats is > 5000 mg/kg. In addition, toxic symptoms such as restlessness, lick, hyperactivity, forced movement, paralysis of the  legs, dyspnea were shown but these symptoms were disappeared after 14 days. Histopathological study showed that there was no change on animal’s organ compared to the normal control.

Abstract

Costus speciosus has been reported to have biological activity among antidiabetic, antihyperlipidemia, antioxidants. One of the chemical constituents that is responsible for some of the biological activity is diosgenin. This study aimed to determine diosgenin content of Costus speciosus water extract (CS). Water extract of CS was obtained with infundation method. The extract was dried using freeze dryer. The assay of diosgenin was performed by HPLC method. HPLC system used: LiChrospher® 100 RP-18 endcapped (5 µm) column length 25cm, colimn id 4 mm as stationary phase, acetonitrile-water (9: 1 v/v) as mobile phase, flow rate 2mL/min and UV detection at 205 nm. HPLC method developed was linear in the range 20-200 μg mL with R = 0.9999 ; slope = 6423.7; and intercept = -4280.5; LOD = 2.14 ug/mL and LOQ = 6.50 mg/mL; and recovery 100.63 %. Diosgenin levels in CS was 0.279 %. The developed HPLC method is relatively simple, rapid, sensitive, and accurate to determine the content of diosgenin in water extracts of Costus speciosus.

Abstract

Background: Hylocereus polyrhizus has activities as antimicrobial agent, anti-hypercholesterolemia, anti-diabetic (diabetes mellitus), cardiovascular risk reduction, health supplement, and melanoma cell suppression. The extracts from the peels of H. polyrhizus were able to increase phagocytic ability, cell numbers and leukocytes and to influence relative spleen weights in the formation of body immune system in male rats. The fruit peels contained phenolics, flavonoids, carotenoids, and anthocyanins. This study investigated the active compounds of H. polyrhizus peels, which are able to increase immune system of human body.Materials and method: In vitro assay was applied to examine the active compounds, identified as lupeol, obtained from isolated extract of red dragon fruit for their lymphocyte proliferation and nitric oxide (NO)-producing activities. Lymphocyte proliferation assay was performed with 3-4.5-dimethylthiazol-2-yl)-2.5-diphenyltetrazolium bromide (MTT) method. The cell control was lymphocyte cell suspension in RPMI medium added with phytohaemaglutinine (PHA). The NO measurement was conducted with nitric solvent and Greiss reagent.Results: The ANOVA analysis of the average optical density (OD) of lymphocyte proliferation showed that the addition of isolated lupeol at the concentrations of 6.25, 12.5, 25, 50 and 100 µg/mL were able to improve lymphocyte proliferation and activate the NO production in the rats with treatment of positive control. Conclusion: Isolated lupeol at concentrations of 6.25, 12.5, 25, 50 and 100 µg/mL revealed significant difference with medium control and cell control. It was able to increase effects on lymphocyte proliferation and NO production. Therefore, the lupeol which was isolated might have high potential to be an immunostimulant.Keywords: Hylocereus polyrhizus, lupeol, lymphocyte proliferation, nitric oxide production
