Bu bilgiyi eğitim notlarımdan çıkardım. Kalmış bir köşede. Zaten bu ağaçtan elde edilen Neemazal ilacı yaprak galeri sineğine etkili. http://www.siu.edu/~ebl/leaflets/melia.htm Bu sitedeki açıklamalar sanıyorum hazırlanması ile ilgili. Preparation of aqueous extract Shade dried plant material (500 g) is ground to a fine powder, poured with distilled water, and left for 72 hours at room temperature. The flask is then refluxed over a hot water bath for 10 hours and the mother liquor is filtered. The solute is again added with solvent (distilled water) that is again refluxed and filtered; this process is repeated for 4 times. The filtrate, thus obtained, is evaporated to complete dryness under reduced pressure on a water bath. The residue thus obtained is the aqueous plant extract. Yields per 1000 g dry material: petrol ~ 11 g, Benzene ~ 12.5 g, EtOAC ~ 9.0 g and MeOH ~ 14.0 g. Aqueous extract material (500 g) (yield ~ 48.0 g). Dried plant extract were stored in labeled sterilized screw capped bottles at -200C Düzenleyen izzeterisen : 26-11-2008 saat 21:14 |
