Abstract

Rimpang Lengkuas (Alpinia galanga L.) merupakan tanaman yang telah banyak digunakan sebagai rempah dan obat tradisional dalam kehidupan sehari-hari. Tanaman ini mengandung senyawa bioaktif flavonoid yang memiliki efek antioksidan. Penelitian ini dilakukan untuk mengetahui pengaruh ketinggian tempat tumbuh terhadap aktivitas antiokasidan dan toksisitas dari ekstrak rimpang lengkuas (Alpinia galanga L.). Ekstraksi dilakukan dengan cara maserasi sedangkan kadar polifenol dan flavonoid total dilakukan dengan menggunakan metode Folin-ciocalteu dan metode kolorimetri yang dianalisis dengan menggunakan alat spektrofotometer UV-Vis. Uji aktivitas antioksidan dilakukan dengan menggunakan metode DPPH (2,2-Difenil-1-Pikrihidrazil) dan sitotoksisitas dengan menggunakan metode BSLT (Brine Shrimp Lethaly Test). Ekstraksi menggunakan pelarut etil asetat diperoleh rendemen sebesar 2,24% untuk dataran rendah,  3,51% dataran sedang dan dataran tinggi sebesar 3,77%. Analisis kadar fenolik dan flavanoid diperoleh berturut turut dari dataran rendah ke tinggi sebesar 6,08±0,26% dan 2,25±0,05%, 5,09±0,14% dan 1,09±0,08, 5,47±0,24% dan 1,16±0,3%. Aktifitas antioksidan yang tertinggi diperoleh pada dataran rendah diperoleh IC50 332,48 bpj, kemudian pada dataran tinggi dengan IC50 447,14 bpj dan pada dataran sedang diperoleh IC50 sebesar 518,57 bpj. Uji sitotoksik terhadap ketiga ekstrak menunjukkan hasil LC50 yang tidak terlalu berbeda antara ketiga lokasi tersebut.

Abstract

Liver dysfunction is implicated with the use of Antituberculosis (AT) leading to low compliance of TB patients to AT regimen. One of biomarker that is important to measure liver dysfunction is total bilirubin serum. Paliasa leaves have been emiprically used to improve liver function in South Sulawesi. This study aimed to determine the effect of ethanolic extract of Paliasa leaves on total bilirubin serum in rats. Twenty rats were devided into five groups: Group I served as the healthy control was only given NaCMC suspension, group II was treated with 178 mg/200gBB of AT suspension, while group III, group IV and group V  were given Paliasa extract 125 mg/kgBB, 250mg/kgBB and 500 mg/kgBB, respectively, 4 hours prior to AT suspension administration. Treatments were performed once a day for 28 days. Blood sampling was carried out 24 hours following the last treatment. The total bilirubin levels were measured using Humalyzer 3500. The results showed that the administrations of AT suspension for 28 days significantly increased rat total bilirubin levels. Paliasa leaf extract in all given dose was able to reduce the total bilirubin levels of rats compared to the group given only AT suspension. However, statistical significance was only reached by the groups that were treated with Paliasa extract 250 and 500 mg/kgBB. Therefore it is concluded that ethanol extract at a dose of 250 and 500 mg/kgBB has protective effect against AT-induced elevation of total bilirubin serum in rats.

Abstract

Zerumbone has been reported for their several biological activities. In our interest to this compound, we have identified and analyzed its content in Zingiber zerumbet, a medicinal plant from Indonesian traditional medicine and investigated its inhibitory activity against Mycobacterium tuberculosis, a known infection bacteria of tuberculosis. Analysis of zerumbone was performed with densitometry to leave, rhizome, flower, and stem of Z. zerumbet which was extracted with various solvent system and extraction methods to determine the best method to isolate zerumbone from Z. zerumbet. Result showed that the highest zerumbone was in rhizome while was not observed in other part. Analysis with various solvent and extraction methods showed the highest yield of zerumbone can be extracted by n-hexane (maceration) and reflux extraction method (methanol). Furthermore, inhibitory activity of zerumbone against M. tuberculosis was tested using Lowenstein Jensen medium by counting the number of M. tuberculosis colony growth in medium. Resulted inhibitory activity of zerumbone at all test concentration (0.5, 0.1, 0.05, 0.01, 0.005%) with the growth of 10, 12, 14, 15, and 50 colonies of M. tuberculosis was observed, respectively. This is indicate that zerumbone can be used as an alternative choice for treatment tuberculosis in the future.
