The methanol extract of A. paniculata has a hepatoprotective effect in (MDA) levels of paracetamol-induced Rattus novegicus with an effective dose of 500 mg kg-1. Keywords: Andrographis paniculata, hepatoprotective effect, malondialdehyde INTRODUCTION Inflammation is a protective response involving host cells, blood vessels, and proteins and other mediators to eliminate the initial cause of cell injury, and the necrotic cells and tissues because of the original insult, and to initiate the process of reparation. There are five local signs of inflammation, i. , calor, rubor, tumor, dolor and functio laesa (Kumar et al. One of drugs that can be used to alleviate the symptoms of inflammation and freely available in Indonesia is paracetamol. Paracetamol has replaced aspirin as a first-line in alleviating inflammatory However, the use of paracetamol in large doses can result in toxic effects and induce hepatic disease . ruginduced liver disease/DILD). Hepatotoxicity may occur when the use of paracetamol is more than 4000 mg per day or more than 2000mg per day for alcoholic patients (Brunton et al. Liver diseases are a public health problem in Indonesia. According to data from the Ministry of Health of the Republic of Indonesia, the number of cases of liver diseases in Indonesia ranks third after infectious diseases and pulmonary diseases. There are about 2,000 cases of acute liver failure that occurs in every year. 50% of them are caused by drug toxicity, 39% due to paracetamol, 13% due to idiosyncratic reaction and 8% due to other medications (Indonesian Health Development and Research 2. Hepatotoxicity occurs because of toxic compounds resulting from metabolism of paracetamol. N-acetyl-pbenzo-quinoneimine (NAPQI), by cytochrome P4502E1 (CYP2E. In normal conditions. NAPQI was detoxified by conjugation with glutathione (GSH) as an endogenous As consequence, conjugation will result in decreases of hepatocellular GSH leading to GSH deficiency in which free-NAPQI will covalently bind to liver cell macromolecules such as lipids and cell membrane proteins that cause liver cell damage and generates freeradical compounds (Rang et al. Free radicals are defined as atoms or molecules that have unpaired electrons in their outermost orbital. These unpaired electrons are highly reactive to bond with other The lipid peroxidation process will occur when free radicals meet with polyunsaturated fatty acids. This lipid peroxidation process produces several compounds such as malondialdehyde (MDA). Excessive amounts of free radicals increase the process of lipid peroxidation resulting in increase of MDA production. Therefore. MDA N U S A N T A R A B I O S C I E N C E 10 . : 87-90. May 2018 levels detected from the liver tissue can be used as a marker of tissue damage due to oxidative stress (Yustika et Andrographis paniculata containing andrographolide and flavonoids are proven efficacious to improve liver cell Andrographolide and flavonoids act as antioxidants and scavenger agents inhibit lipid peroxidation that can be demonstrated by decreasing MDA levels as lipid peroxidation products. Therefore, this study was aimed to examine the hepatoprotective effect of methanol extract of A. paniculata and to compare the hepatoprotective effect of methanol extract of A. with curcumin as a substance known as hepatoprotectant (Goenarwo et al.

Statistical tests performed on average of MDA levels of hepatic tissue group dose 3 showed statistically significant differences over all other groups other than the dose 2 (Post Hoc Test LSD, p <0. Discussion Paracetamol induction in the negative control group without any hepatoprotector substance was conducted to show the lipid peroxidation process due to the oxidative stress occurring in paracetamol hepatotoxicity. The treatment of paracetamol as much as 900 mg kg-1 was induced by administering it solely to be able to give toxic The MDA level of the negative control group was significantly different and had a higher value when it was compared with the normal control group. This happened because antioxidant defense mechanisms failed to prevent the formation of excessive ROS. This proves that paracetamol in toxic doses will trigger oxidative stress in hepatic tissue leading to lipid peroxidation and resulting in MDA products. The oxidative stress is caused by the metabolic process of paracetamol in the liver by CYP450 mainly by the enzyme CYP2E1 which causes the formation of intermediate compounds in the form of reactive NAPQI. NAPQI will form covalent bonds with intracellular proteins and disrupt intracellular function such as the decrease amount of calcium ions in the cytosol leading to lipid peroxidation of the membrane which finally causes cell death (Basu et al. MDA levels in the negative control group were significantly higher than those in positive control. This shows that oxidative damage is attenuated by the administration of curcumin. Curcumin is a scavenger agent, which can protect the tissue from free radicals generated from oxidative stress. thus, lipid peroxidation and cell membrane damage were limited (Somnawat et al. MDA levels in liver tissues of rats in dose 1, dose 2, and dose 3 group were significantly lower and different than those in the negative control group. Based on this, it can be concluded that the methanol extract of A. has hepatoprotective effect by inhibiting free radical in paracetamol-induced rats, which could be observed from the decreased levels of MDA in liver tissues as lipid peroxidation products due to oxidative stress. This condition is in accordance with Bardi et al. who reported that the administration of methanol extract of A. paniculata at a dosage of 500 mg kg-1 significantly decreased MDA levels of liver tissues of thioacetamideinduced rats. Hepatoprotective effect of methanol extract of A. paniculata is caused by 2 active substances contained in A. paniculata, namely andrographolide and flavonoids. Kamdem and Ho . conducted a study of the active compound of andrographolide. Andrographolide is the main active substance in the A. paniculata that works by acting as an exogenous antioxidant. Andrographolide has aliphatic hydrogen groups on C-11 carbon atoms which can act as a hydrogen donor to pair with unpaired electrons from free radicals. In other words, andrographolide acts as a free radical scavenger breaking the lipid peroxidation chain in a series of oxidative stresses causing decreased levels of MDA as a product of lipid peroxidation. Flavonoids decrease MDA levels of liver tissue by working as exogenous antioxidants and increasing endogenous antioxidant biosynthesis. Flavonoids are known as an antioxidant, which can inhibit cell damage due to paracetamol metabolism. Flavonoids have hydroxyl phenolic (OH) groups in their molecular structure, which have the role of alic hydrogen groups in andrographolide. The OH group acts as a free radical scavenger agent because it attracts free radicals. OH groups in flavonoid compounds will replace endogenous GSH antioxidants that have been depleted by free radicals due to toxic doses of The OH group on flavonoids will help conjugate paracetamol into mercapturic acid and convert NAPQI into a hydrophilic non-active metabolite so that it is easily excreted through urine (Yousef et al. Flavonoids play a role in GSH biosynthesis through de novo pathway by stimulating GCL gene expression that acts as a catalyst and modulator GSH formation by de MDA levels as lipid peroxidation products decline because of the oxidative stress mechanism inhibited by increased production of endogenous antioxidants GSH (Mari and Nieto 2. The effective dose of this study was done from the smallest dose group that had the effect and approached the positive control group. in this study, it was found that in the dose 1 group. MDA levels of liver tissue were not significantly different with the positive control group. So it can be concluded that the effective dose in this study is 500 mg kg-1 of methanol extract of A. Methanol extract of A. paniculata has a hepatoprotective effect, which was proven by the decreased N U S A N T A R A B I O S C I E N C E 10 . : 87-90. May 2018 levels of MDA in liver tissues of paracetamol-induced Wistar rat (Rattus norvegicu. The effective dosage of methanol extract of A. paniculata in this study was 500 mg However, further studies on A. paniculata extract as a hepatoprotective agent are required so that it can be used hepatoprotective effect on the isolated andrographolide.
