We present an X-ray and UV investigation of five X-ray flares detected on twoactive systems, CC Eri and AB Dor, using the AstroSat observatory. The peakX-ray luminosities of the flares in the 0.3$-$7.0 keV band are found to bewithin 10$^{31-33}$ erg s$^{-1}$. Preliminary spectral analysis indicates thepresence of three and four-temperature corona for CC Eri and AB Dor,respectively, where the highest temperature is found to vary with flare. Theflare temperatures peaked at 51$-$59 MK for CC Eri and 29$-$44 MK for AB Dor.The peak emission measures of the flaring loops are estimated to be$\sim$10$^{54}$ for CC Eri and $\sim$10$^{55}$ cm$^{-3}$ for AB Dor. Globalmetallic abundances were also found to increase during flares.
