COMPARISON OF METHODS OF PRODUCING BEE PROPOLIS PURIFIED EXTRACT BASED ON TOTAL FLAVONOID CONTENT USING RUTIN AS STANDARD

Propolis is a complex mixture of beeswax, sugar, and gum trees collection of honeybees (Apis mellifera). One of the compounds that have a pharmacological effect is flavonoid. Flavonoid can be obtained in large concentration and high purity with purified extraction method. The extraction was done with 96% ethanol, followed by purification with 30% ethanol, chloroform, ethyl acetate (in Method I), or followed with hot water and ethyl acetate (in Method II). The content of flavonoids detected by Thin Layer Chromatography, the stationary phase, silica gel 60F 254, the mobile phase n-butanolacetic acidwater (3: 1: 1 % v/v ). The total flavonoid concentration was measured by UV-Vis spectrophotometer based on Zou method, calculated as routine. Results were analyzed by paired sample t-test. The mean level of total flavonoids from propolis extract before purification was 1.23 ± 0.3698 %w / w. Purification of ethanolic extract of 96% propolis with Method I and II, resulting in a total flavonoid concentration of 9.97 ± 1.5656 (8.1 times) and 11.78 ± 1.2965% w / w (9.6 times). Paired samples t-test with SPSS 16 showed the effectiveness of purification with significance value 0.048.

Antiinflammatory Effect of Several Umbelliferae Species

Since the discovery of cryopreservation method for bull semen, cryopreservation become an alternative method for maintaining gamet resources of certain animal which is threatened or near extinction. This technology was then applied to the preservation of embryo, oocyte, ovary and testis. The application of intracytoplasmic sperm injection (ICSI) for which sperm motility is unnecessary had supported the effort to create simplified method such as freeze-drying for sperm preservation. Due to the benefit of ICSI over the conventional in vitro fertilization (IVF) the spermatozoon could be mechanically driven to pass through the zona pellucida and entering the cytoplasm of oocytes prior to fertilization. The freeze-drying method is an alternative method in sperm preservation which ignored the motility of sperm. The sperm resulted from this technique is in drying state, therefore, it might be stored in room temperature or in refrigerator. Many reports have claimed that freeze-dried sperm which is not motile but has an intact DNA was able to fertilize oocytes, even produced offspring in mouse.A screening for antiinflammatory effects was performed on several Indonesian Umbelliferae plants based on the contents of saponins and flavonoids. They were compared with Bupleurum falcatum L. as an introduced antiinflammatory plant. Roots and grains of each plant were collected, dried, and extracted with ethanol. The ethanolic extracts were then analyzed for their saponin and flavonoid contents by gravimetric and UV-vis spectrophotometric method. Antiinflammatory activity test was conducted on carragenin induced rat paw oedema. The results showed that the highest contents of saponin and flavonoid were found in the grains of Apium graveolens L. and showed antiinflammatory effect that was equivalent to that of the root of B. falcatum.
