Larvicidal Activity of A Mixture of Cashew Nut Shell Liquid and Water-Soluble Extract of Soap Nut Fruit (Sapindus rarak DC.) Against 3rd Instar Larvae of Aedes aegypti
Cashew Nut Shell Liquid (CNSL) which has been known as a waste of processing cashew fruits which is contain phenolic compounds have activity as larvicides. Cashew nut shell liquid is not soluble in the water where the larvae grow. Cashew nut shell liquid mixed with water-soluble extract of soapnut fruit which serves as a natural surfactant that can emulsify oil in water. The test subjects were larvae of Aedes aegypti third instar. Test subjects were divided into treatment group and control group. In the treatment group, test subjects were the mixture of CNSL and Ethylacetat Soluble Extract (ESE) in tap water. The Larvae mortality observations were done 24 hours after the treatment. LC50 and LC90 as final test data were analyzed using probit analysis. Extract constituents   of CNSL and Water Soluble Extract of SoapNut fruit (WSEoSN) were  investigated using Thin Layer Chromatography (TLC) method. The effect of CNSL as larvicides against third instar larvae of Ae. aegypti with were LC50 of 14,12 ppm, while the LC90 of 24,85 ppm
Antioxidant Potential of Black, Green and Oolong Tea Methanol Extracts
Degenerative diseasesandchronicdiseasesare oftencausedbyoxidativestress. Oxidative stress caused by free radicals. Antixodant as inhibitor are needed to prevent it which is one of antioxidant sources is tea. Tea processinggenerally produce various kinds of teas such as black, green and oolong tea. Tea processing affect thecontent ofphenolic compounds. The aim of the research is to evaluate phytochemical content, totalphenolic content of blacktea, green tea andoolongtea extracts using catechin, quercetin, kaempferol, myricetin as standard, and to evaluate the antioxidative potency of black tea, green tea and oolong tea extracts compared to catechin, quercetin, kaempferol, myricetin. Phytochemical assay using modified Farnsworth method, the antioxidant activity were measured by  by its 1,1-diphenyl-2-picryl-hydrazyl (DPPH) scavenging activity. Green tea extract contained highest phenolic and flavonoid.  The highest antioxidant activity was green tea extract with IC50=0,487μg/mL. Green tea extract content phenol and flavonoid are higher compared to the other extracts, green tea extract has the highest antioxidant activity
A Simple and Practical Method for Rat Epididymal Sperm Count (Rattus norvegicus)
Sperm sample from epididymal source can be determined its number using minimal amount of equipment. These method will aid researcher and practitioner in sperm quality analysis to determined sperm number rapidly and practically
Tapak Liman (Elephantopus scaber L) As Immunostimulant and Its Effect on Lymphocyte Differentiation in Mice BALB/C
Tapak liman (Elephantopus scaber L) is one of the plants that have medicinal properties and has been used for maintenance and improvement of health and disease treatment. The purpose of this study was to determine the effect of extracts of Tapak Liman (Elephantopus scaber L) as immunostimulant to the development of lymphocytes in mice BALB / C. The procedure of this study was to test aqueous extracts in vivo with various treatments (control, treatment of 0.5 g / kg, 1.0 g/ kg, 2.0 g / kg) in healthy mice BALB / C for 2 weeks. After the treatment carried out analysis of the percentage and number of cells that express CD4+, CD8+ and CD4+ CD8 + in thymus organ, using flowcytometry. Analysis of data using one-way ANOVA followed Tukey's test with SPSS. From the analysis showed that the extract of Tapak liman at various doses showed no significant effect on the percentage expression of CD4 + CD8 + and CD4 + CD8 + in thymus organs. While the analysis of the number of cells, extracts of Tapak liman show its effect on the number of cells that express CD4+, CD8 + and CD4 + CD8 + in thymus organs. Concentration of 1.0g / kg of mice showed a good effect on the increase in T helper cells (CD4 +), cytotoxic T cells (CD8 +) and Prothymosit cells (CD4 + CD8 +)
The Phytoestrogenic Potential of Yam Bean (Pachyrhizus erosus) on Ovarian and Uterine Tissue Structure of Premenopausal Mice
The use of estrogen hormone by public has significantly been improved either as prevention or treatment of disease. Menopausal issues in women are often treated using hormone replacement therapy. In regard to this, yam bean is found to contain genistein and daidzein compounds with a chemical structure that resembles estrogen hormone, therefore yam bean is categorized in the phytoestrogen group. The purpose of this study was to identify the potential of yam bean on ovarian and uterine histology of mice. This research employed a Completely Randomized Design of experimental research approach of one factor namely yam bean in three different dosage treatment: 0.3 g/kg, 0.6 g/kg, and 0.9 g/kg of yam bean for 24 days. The surgery and organ harvesting of ovary and uterus were conducted on Day 25 along with the making of histological preparat using paraffin method and Hematoxylin-eosin (HE) staining. The data was then analyzed descriptively. This research found that there were both secondary and tertiary follicle proliferation as the antrum contains some estrogen level. Meanwhile, the endometrial tissue of the uterus experienced uterine glandular proliferation. To conclude, yam bean was found to be a natural estrogen source
Krokot Extract (Portulaca Oleracea. L) as Natural Light-harvesting pigments for Dye-Sensitized Solar Cells (DSSCs) : Influence of Dye Acidity
Dye-sensitized solar cells (DSSCs) was fabricated using natural dyes extracted from krokot (Portulaca Oleracea. L). The effect of dye acidity was investigated on natural pH extract, 5.00, 4.00 and 3.00 of pH. The efficiency and stability DSSCs as a function of the dye acidity was studied. The result of the UV-Vis shows that the absorption of wave-length from dye extract of krokot is located in the visible region with the absorbance peak in 410.5 nm and 664.5 nm which are the peak of chlorophyll. The efficiency of extract krokot dye sensitized solar cells was decreasing 6.88 x 10-3 % to 0.42 x 10-3 % when pH of the dye was adjusted from 6.27 to 3.00. DSSCs stability was also decreased look for efficiency loss from 5.27% to 97.49% in the same conditions
Medicinal Plants: A Prospect in Developing Male Fertility Enhancing Agent
Medicinal plants have been a revolutionary breakthrough in the treatment of male sexual dysfunction. Traditional medicine based on a holistic philosophy is quite different with the practice of “western†medicine. Phytochemical substances focus their mechanisms of healing to the root of cause, i.e. the inability of controlling the proper function of the whole body system. Hence, medicinal plants manage sexual dysfunction and male fertility in the frame of sexual dysfunction as a whole entity. Some previous researches prove that the use of medicinal plants have a good impact in the treatment of a variety of male sexual problems. This paper will discuss several important aspects of aphrodisiac plants and preliminary study regarding them in Indonesia. Difficulties inherent to activity guided isolation and the specific requirements of bioassays are also discussed
