Preface Rector of UMP Assalamu’alaikum wr. wb. Alhamdulillah, that UMP will carry out prestigious event namely “National Olympiad and International Conference on Education, Technology, and Science (NETS) 2013” is a very great news for me. NETS 2013 is the first event which is conducted in collaboration between UMP and PWM Central . It is a great event which is constructively supported by ITB, UNiSA, UTeM, and several institutions under UMP partnership to smoothen the event. Recently, technology grows very fast. This fast growth affects on the quality of education in . Based on this condition, UMP and PWM Central Java formulate a program which later it is formed into “NETS 2013”. This event is also a contribution to Islamic Higher Education Institution to prepare candidate of future leaders who have competitive skills to compete positively in comprehending knowledge and technology. In NETS 2013, there are some events which are arranged in a sequence such as: International Conference on Education, Technology, and Science (ICETS) with Prof. Dr. Ir. Imam Robandi, M.T., Mr. Ganjar Pranowo, Mr. Simen Lourds, and Dr. Hiroshi Takeda; Seminar (Call for Paper) including some disciplines of science covering Education, Engineering, Medicine, Science, Social, Politic, Religion, Law, Culture, Arts, Agriculture, and Technology; National Olympiad for Student and Teacher (NOST) which is joined by students, teachers, and schools; and Expo. In NETS 2013 competitions, participants are fighting over trophies, medals, certificates, and advisory fund reaching up to Rp250.000.000,- ; furthermore, there is also a fellowship to study in UMP. As the Rector of The University of Muhammadiyah Purwokerto, I do really expect that conducting this event could encourage all of us to be more advanced nation not only on economic side, but also on social life. It is also expected that this event will increase our awareness on how important it is to develop and advance technology in education. That is all I could deliver now, for further information you may access our website on www.ump.ac.id. Last but not least, “Let’s join and support NETS 2013 in UMP”. Wassalamu’alaikum wr. wb.

THE COMPARISON OF FREE RADICALS SCAVENGING ABILITIES BETWEEN ETHANOL EXTRACTS OF PURWOCENG (Pimpinella pruatjan Molk.) HERBS AND LEAVES

Balqis Hisyam Saleh Basleman, Wiranti Sri Rahayu, Retno Wahyuningrum Pharmacy Faculty of Muhammadiyah University of Purwokerto

Abstract has been widely reported have medicinal properties Flavonoids and tannins are potentially as free as aphrodisiac, diuretic, and tonic. This plant is radicals scavenger. Purwoceng has some of the native plant from Indonesia which live in endemic compounds such as flavonoid, glycosides, and areas, such as mountainous Dieng plateau in tannins. Research done by using DPPH and Nitric Central Java, mount Pangrango, West Java and East oxide (NO•) radicals. The treatment of ethanol Java’s mountainous areas. extracts of purwoceng leaves with the scavenging According to Caropeboka and Lubis (1975), activity of radical DPPH 38,65 ppm and NO• 14,73 root extract of purwoceng motor activity, which ppm results IC30 smaller when compared with the heightens tonus striated muscles, stimulates central ethanol extract of purwoceng herbs by the nervous arrangement with capture point work on scavenging activity of radical DPPH 57,25 ppm the medulla oblongata, sexual behavior and to and NO• 28,88 ppm. The free radicals scavenging improve male mice (Caropeboka et al., 1979 in S. abilities of ethanol extracts of purwoceng leaves Usmiati and S. Yuliana, 2010). So it is said that better than free radicals scavenging abilities of purwoceng’s root extract has an androgenic activity ethanol extracts of purwoceng herbs. in mice. Saponin group is the one of chemical Keywords: free radicals, Purwoceng, DPPH, nitric compound as secondary metabolites in purwoceng oxide plant. There are also triterpenoidsteroids, sitosterol, and stigmasterol compounds. Purwoceng INTRODUCTION plant also contains coumarin, alkaloids, flavonoids, Free radicals is an atom or group of atoms that glycosides, and tannins. By looking at the content has a highly reactive characteristic caused by the of secondary metabolites of purwoceng plant which presence of one or more free electrons or electrons are flavonoids and tannins (Haryono, 2013), is are not paired, so that it becomes unstable and high needful to do more researchs to find out the energy (Fessenden and Fessenden, 1982). To avoid potential of the power of free radicals scavenging of the free radicals attack, is by consuming natural purwoceng plant either the leaves or herbs because antioxidants in sufficient amount each day. Anti for specific flavonoid compounds are concentrated free radical is a compound which in a small amount in the leaves (the herb Information, 2012; Waji et when compared with the substratum is capable of al, 2009). delaying or preventing or avoiding the oxidation of substrates which are easily oxidized (Halliwell and RESEARCH METHODS Gutteridge, 2000). Tool Flavonoids are natural phenolic compounds The tools used in this research include: glass are potentially as free radicals scavenger and have tools (measuring flask, measuring cup, test tubes, bioactivities as a medication. Generally, leaf, root, erlenmeyer flask), micro pipette, Ultrasonic bath, stem and flower are the part of plant that save many Rotary Evaporator, analytic scales, maceration, flavonoids as secondary metabolites (Waji et al, cupboard dryer, exicator, UVVis 2009). Another natural phenolic compounds that Spectrophotometer. potential as a free radicals scavenger is tannin. Tannins can be found in all parts of the plant, but at Materials some plants, tannin concentrated on specific parts 1. Material Test (Hernawan and Setyawan, 2003). One of the plants Ethanol extracts of purwoceng herbs and that contain flavonoids and tannins as secondary ethanol extracts leaves (Pimpinella pruatjan metabolites is purwoceng (Haryono, 2013). Molk.). Purwoceng (Pimpinella pruatjan Molk.) is a medicinal plant. Commercially, purwoceng’s root

Results of The Determination of Maximum Wavelength (λ max) Results of maximum wavelength determination with the DPPH radical is 516 nm with maximum absorbance for an ethanol extract of purwoceng leaves is 0,756, ethanol extract of purwoceng herbs is 0,752, quercetin is 1,005 and BHT is 0,756. This means that for power of free radicals scavenging test performed on maximum λ 516 nm. Capture 2. Scanning (λ max) Sodium Nitroprusside Solution 10mM

b. Power Test Results of FreeRradicals Scavenging Power test results capture free radicals can be seen from the percent inhibition of free radical DPPH and NO• ethanol extracts of leaves and ethanol extracts of herbs of purwoceng, quercetin and BHT which shown in tables II, III, IV and V. Where the higher concentration of the extract is used so the Capture 1. Scanning (λ max) DPPH Solution percent inhibition is also higher which means 0,4mM the better the free radicals scavenging power.

Percent inhibition was analyzed to find out to inhibit 30% of free radicals. The higher of I% value know IC30 value, is using curve relationship accordingly the IC30 is lower. The lower of IC30 between percent barrier with a concentration make the better of free radical power inhibition. (Gulluce et al, 2006). The magnitude of free radical IC30 is used because if used IC50 the result can have scavenging power characterized by the IC30 value, extrapolation outside the range series of is the solution concentration of samples needed to concentration.

From the value data of IC30 can be concluded Based on table 7. the IC30 value of ethanol that free radical scavenging power of ethanol extracts of purwoceng leaves and ethanol extract of extract of purwoceng leaves is better then ethanol purwoceng herbs by DPPH radical greater than by extract of purwoceng herbs. NO• racidal. This is possible because both radical have differences in how forms a stable compound. 4. Comparison of Free Radicals Scavenging Another possibility is a compound that plays a role Power in the free radicals scavenging from ethanol extract The use of different methods for determining of prwoceng leaves and ethanol extracts of the free radicals scavenging power of plant extracts purwoceng herbs namely flavonoids less reactive can shown the random results, it is difficult to against DPPH radical because of steric hindrance, compare and sometimes give rise to incompatibility so that only a small molecule that has a greater (Koleva et al. 2002 in Irawati 2008). opportunity to react with DPPH radical (Irawati, 2008).
