CLEFIA, a new 128-bit block cipher proposed by Sony Corporation, is increasingly attracting cryptanalysts＇ attention. In this paper, we present two new impossible differential attacks on 13 rounds of CLEFIA-128. The proposed attacks utilize a variety of previously known techniques, in particular the hash table technique and redundancy in the key schedule of this block cipher. The first attack does not consider the whitening layers of CLEFIA, requires 21~9＂5 chosen plaintexts, and has a running time equivalent to about 2112.9 encryptions. The second attack preserves the whitening layers, requires 2117.8 chosen plaintexts, and has a total time complexity equivalent to about 2121.2 encryptions.

Two compounds with different bioactivities were isolated from the leaves of the Lantana camara Linn *** 1 was triterpenoid(Lantadene B)(22β-dimethylacroyloxy-3-oxoolean-12-en-28-oic-acid,C_(35)H_(52)O_5),which was isolated from n-hexane fraction and obtained as white solid(amorphous).Compound 2 was glycoside flavonoid(5-hydroxy-6,4′-dimethoxy flavon-7-O-glucopyranose,C_(23)H_(24)O_(11)),which was isolated from ethyl acetate and obtained as pale yellow solid(amorphous).Extraction was performed with maceration method using methanol ***,fractionation was carried out using n-hexane and ethyl acetate *** and purification of both fractions were conducted using chromatography *** structure of the isolated compounds was determined through spectral analyses of ultraviolet(UV),infrared(IR),and nuclear magnetic resonance(~1H NMR and ^(13)C NMR),distortionless enhancement by polarization transfer(DEPT),heteronuclear multiple bond connectivity(HMBC),heteronuclear single quantum correlation(HSQC),and H-H COSY(~1H-~1H homonuclear correlated spectroscopy).The cytotoxic activity of compound 1 was tested against MCF-7 breast cancer cells in vitro using MTT assay(3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide),showing very strong cytotoxic activity in inhibiting the growth of MCF-7 breast cancer cells,and the IC_(50) value was 1.1336μ*** antioxidant activity of compound 2 was tested using DPPHassay(1,1-diphenyl-2-picrylhydrazyl),showing strong activity in inhibiting free radicals,and its IC_(50) value was 71.03 mg/L.
