Standardization of Pegagan Extract, Centella Asiatica as Hepatoprotectiveherbal Medicine
Herbal medicinal products would be affected by the quality of raw materials. In turn, the quality of raw material will also be influenced by various factors such as soil conditions, cultivation, post-harvest processing, and the processing of raw materials into crude drug or extract. Therefore, in order to make good herbal medicines, it is necessary to make standardization of herbal extracts that produced herbal medicines that have the same quality and functions of effectiveness in each process. From preliminary studies that have been done, Centella asiatica is one of the potential plants as a source of hepatoprotective compounds. Test in vivo and in vitro against Centella asiatica extracts have shown very good results. Ethyl acetate extract with 17.5 mg/kg of doses body weight and butanol 228.8 mg/kgof doses body weight has been applied for in vivo test using mice induced by CCl4; theydemonstrated hepatoprotective effects. Ethyl acetate extracts were able to reduce levels of the enzyme alanine aminotransferase (ALT) and aspartate aminotransferase (AST) by 56 % and 44 % respectively while butanol extract can reduce the enzymes AST levels by 3%. Standardizationof Centella asiatica extract performed in this study was the characterization of the extract in the form of non-specific and specific parameters corresponding to the reference of PPOMN (Ministry of health Republic of Indonesia, 2000) such as levels of drying shrinkage, ash content, total plate count microbial contamination, levels of water-soluble compounds, levels of compounds that are soluble in ethanol, phytochemical test, total phenolic content, total flavonoid content and the determination of Pb and Cd weight.The results showed that non-specific parameters for the ethanol extract of Centella asiatica were requirements based on Herbal Pharmacopoeia in 2008 which includes parameters such as determination of shrinkage on drying ≤ 10%, ash content ≤ 16.6% and negative microbial contamination. Specific parameters for the ethanol extract of Centella asiatica have met the requirements of Herbal pharmacopeia in 2008
Isolasi Siklokomunol Dari Daun Sukun Artocarpus Altilis (Parkinson) Fosberg Serta Aktivitasnya Sebagai Antikanker
Daun sukun (Artocarpus altilis) sudah lama dijadikan sebagai obat tradisional untuk mengatasi berbagai penyakit seperti liver cirrhosis, hipertensi, dan diabetes. Ekstrak etil asetat dari daun sukun juga berpotensi menghambat pertumbuhan sel kanker. Beberapa senyawa yang telah diketahui sebagai agen antikanker di dalam ekstrak etil asetat daun sukun adalah golongan geranil flavonoid. Akan tetapi, senyawa pyranoflavoid belum dilaporkan dapat ditemukan pada daun sukun. Untuk itu, penelitian ini bertujuan untuk mengisolasi senyawa pyranoflavonoid dari ekstrak etil asetat daun sukun dan menguji aktivitasnya sebagai antikanker. Daun sukun diekstraksi dengan etanol 70% kemudian dilakukan partisi dengan petroleum eter dan etil asetat. Ekstrak etil asetat yang diperoleh difraksinasi dengan kromatografi kolom silica gel dengan gradient elusi heksan-etil asetat sehingga diperoleh senyawa kristal berwarna kuning, AA3. Senyawa AA3 kemudian diidentifikasi dengan spektrofotometer UV-Vis, LC-MS, 1H-NMR dan 13C-NMR dan diperoleh hasil bahwa senyawa AA3 tersebut adalah siklokomunol yang merupakan golongan pyranoflavonoid. Uji antikanker siklokomunol dengan MCF-7 dan T47D menunjukkan adanya aktivitas antikanker dengan nilai IC50 masing-masing adalah 75.46 µM dan 36.20 µM selama 48 jam.Kata kunci:Artocarpus altilis, siklokomunol, antikanker, MCF-7, T47D. Leaves of breadfruit Artocarpus altilis (Parkinson) Fosberg has long been used as traditional medicine to overcome a variety of diseases such as liver cirrhosis, hypertension, and diabetes. Ethyl acetate extract of the leaves of breadfruit also potentially inhibit the growth of cancer cells. Several compounds have been known as an anticancer agent in the ethyl acetate extract of leaves of breadfruit is belong to geranyl flavonoid group. However, the compound belong to pyranoflavoid group has not been reported can be found on the leaves of breadfruit. Therefore, this study aims to isolate the pyranoflavonoid compound from ethyl acetate extract of leaves of breadfruit and tested as an anticancer agent. Breadfruit leaves were extracted with 70% ethanol and then made a partition with petroleum ether and ethyl acetate. Ethyl acetate extract obtained was fractionated by silica gel column chromatography with gradient elution of hexane-ethyl acetate to obtain a yellow crystalline compound, AA3. AA3 compound was identified by UV-Vis spectrophotometer, LC-MS, 1H-NMR and 13C-NMR and obtained results that AA3 compound is siklokomunol which is belong to pyranoflavonoid group. Anticancer test of siklokomunol with MCF-7 and T47D showed anticancer activity with IC50 values of each are 75.46 µM and 36.20 µM, respectively, for 48 hours
