Abstract

Some plants, such as Ipomoea batatas Poir., Mussaenda pubescens Ait. F., Portulaca oleracea L., Brucea javanica L. (Meer), have been used traditionally to treat cancer, even though the scientific base of this activity has yet been completely investigated. The study was conducted to evaluate the cytotoxic activity of these plants on HeLa cell lines.The cytotoxicity of chloroform extract from these plants were determined using micro radioactive method by measuring an incorporation (3H)-hipoxanthine on the cells after 24 and 48 hours incubation with each extract, using doxorubicine as a positive control. Extract free cell culture was refered to as 100% growth. IC50 value, showing 50% inhibition of the cell growth, was determined based on the concentration versus percentage inhibition curves.The result showed the extract B. javanica was the most active to hela cells with the IC50 value of 13.69 1.07 and 55.78.4 g/ml after 24 and 48 hours incubation respectively.Key words: Ipomoea batatas Poir., Mussaenda pubescens Ait.

Abstract

Most purification approaches of Ribosome-inactivating Proteins (RIPs) used a cation exchange chromatography resulting highly basic proteins, such as MJ-30 isolated from Mirabilis jalapa leaves. The M.jalapa unbounded protein fractions of the column showed cleavage activity on supercoiled double stranded DNA and possesed cytotoxic effects on cancer cell lines. So the purification and characterization of the acidic protein was needed to be done.Total proteins of M.jalapa leaves was collected from precipitating process of the extract using ammonium sulphate untill saturated. After dialysis, the proteins was applied into the weak base anion exchanger Ionenaustaucher Typ II. The bounded proteins was eluted with 0.0 to 0.5 M NaCl gradient in phosphate buffer. Active protein fractions were determined by supercoilded DNA cleavage activity and then cytotoxic activity was testes.Results showed that protein fraction eluted at 0.35 – 0.40 M NaCl possesed cleavage activity on supercoiled DNA. The acidic protein, MJ-C, was toxic on HeLa, Myeloma and T47D cell lines, with the LC50 of 14.3 μg/mL, 7.4 μg/mL and 27.8 μg/mL, respectively. The MJ-C was more potent than the basic protein MJ-30.Key words: acidic RIP, cytotoxic, Mirabilis jalapa
