“…Then ten adult insects were released into the middle of the petri-dish. Insects were counted after 1 h and then at hourly intervals for 5 h. The average of the counts was converted to percentage repellency using the formula: PR = (Nc-5) × 20 Where, Nc was the average hourly observation of insect on the untreated half of the disc [30,31].…”

Petroleum (Pet.) ether, CHCl 3 and CH 3 OH extracts of Cassia renigera Benth. were tested against Callosobruchus chinensis L. for dose-mortality and repellency; and against Sitophilus oryzae L. and Tribolium castaneum (Hbst.) for repellent activity test. The Pet. ether extract of leaf was found active against C. chinensis adults through dose mortality assay and the LD 50 values established were 9.270, 4.932, 2.032, 1.721, 1.671, 1.543, 1.513, 1.503 and 1.478 mg cm -2 for 0. 5,6,12,18,24,30, 36, 42 and 48 h of exposure respectively. However, the leaf extracts of CHCl 3 and CH 3 OH; as well as the Pet. ether, CHCl 3 and CH 3 OH extracts of the stem-bark did not give mortality to the test organism. The CHCl 3 extract of leaf showed repellent activity against Tribolium castaneum at 0.1% level of significance (P < 0.001), and the Pet. ether extracts of the leaf and the CH 3 OH extracts of the stem-bark offered repellency at 1% level of significance (P < 0.01) between dose levels. Only the CHCl 3 extracts of the stem-bark gave repellency at 5% level of significance (P < 0.05), while the CH 3 OH extracts of leaf and Pet. ether extract of stem-bark did not show any significant repellency at all.

Antioxidant is a new hype in naturopathy and at present it has huge demand in cosmetic, nutritional supplementation and pharmacological industry. It reduces cell damages caused by free-radical which are responsible for various ailment like ageing, cancer, coronary heart disease, diabetes mellitus, neurodegenerative disorders, atherosclerosis, cataracts and inflammation. At present any comprehensive data on the antioxidant content and extent of their activity of the indigenous medicinal plants of Bangladesh is not available. Therefore, here antioxidant activity of a popular medicinal plant -Ficus racemosa was determined. Methanolic extract was prepared from the leaf and stem bark of F. racemosa. Their total phenolics and free radical scavenging capacity was determined using folin-ciocalteu reagent (FCR) assay and DPPD-radical scavenging assay respectively. Stem bark and leaves of F. racemosa contains 242.97 and 235.45 mg of GAE / gm of dried extract of phenolics respectively. Current studies also show that F. racemosa barks contain a high antioxidant activity. IC 50 value of bark extract was found to be 19µg/ml which is even better that of the standard BHT. Therefore, present studies suggest that F. racemosa bark has a huge potential in terms of commercial use as source of antioxidant.Key word: Ficus racemosa, plant extract, phenolic conttent, antioxidant. mvivsk: cÖ K… wZZ ‡Z¡ ( †bPv ‡ivc¨v_x ‡Z) A¨vw›UAw· ‡W›U GKwU mv¤úª wZK AvKl© Y Ges eZ© gv ‡b cÖ mvab, cy wó mn ‡hvMx Ges Jlawk ‡í Gi cÖ Pz i Pvwn`v i ‡q ‡Q| Giv †` ‡ni Af¨šÍ ‡i cÖ wZwbqZ m" ó gy ³ AYy KZ… © K m" ó †Kvlxq ¶wZ (W¨v ‡gR) n« vm K ‡i, hv wewfboe kvwiwiK Amȳ' Zv †hgb eqme" w×, K¨vÝvi, ü` ‡ivM, Wvqv ‡ewUm, ¯oe vhy ‡ivM, nvo ¶q, Qvwb I cÖv ‡ni Rb¨ `vqx| Ghver ch© šÍ evsjv ‡`kx Jlwa Dw™¢mg ‡n we`¨gvb A¨vw›UAw· ‡W ‡›Ui cÖ K… wZ Ges Zvi Kvh© KvwiZv m¤ú ‡K© cwicỸ© †Kvb avibv †bB| ZvB GLv ‡b GKwU RbwcÖ q Jlax Dw™¢ Wz gy i (dvBKvm †iwm ‡gvmv) Gi A¨vw›UAw· ‡W ‡›Ui Kvh© KvixZv hvPvB Kiv n ‡q ‡Q| GB Kv ‡Ri Rb¨ Wz gy i Mv ‡Qi cvZv I evKj Gi wg_vbj wbh© vm ˆZwi Kiv n ‡q ‡Q Ges Zvi g ‡a¨ we`¨gvb m¤úỸ© ‡dbj Dcv`v ‡bi cwigvY I Zvi gy ³ AYy i AcmviY ` ¶Zv cwigvc Kiv n ‡q ‡Q h_vµ ‡g dwjb-K¨vjPz cwi ¶Y I wWwcwcGBP-gy ³ AYy i AcmviY ` ¶Zv cwi ¶Y Gi gva¨ ‡g| Wz gy i Mv ‡Qi evKj I cvZvi cÖ wZ MÖ vg ï®‹ wbh© v ‡m h_vµ ‡g 242.97 Ges 235.45 wg.MÖ v. mgcwigvY wRGB ‡dbwjK Dcv`vb i ‡q ‡Q| cix ¶ ‡Y †`Lv hv ‡"Q †h, Wz gy i Mv ‡Qi evK ‡ji D"P A¨vw›UAw· ‡W›U Kvh© KvwiZv i ‡q ‡Q| Gi evK ‡ji IC 50 gvb 19 gvB ‡µvMÖ vg/wgwj wjUvi hv GgbwK GB cix ¶ ‡Y e¨eüZ ÷¨vÛvW© weGBPwU Gi ‡P ‡q fv ‡jv| my Zivs, GB cix ¶Y GUv cÖ gvY K ‡i †h, A¨vw›UAw· ‡W ‡›Ui Drm wnmv ‡e evwYwR¨K e¨env ‡ii † ¶ ‡Î Wz gy i Mv ‡Qi evK ‡ji cÖ Pz i m¤¢ vebv i ‡q ‡Q|
