Effect of solvent temperature and dissolving time on the amount of yield from moringa (Moringa oleifera) leaf extractions
Pengaruh suhu pelarut dan waktu pelarutan terhadap jumlah rendemen dari hasil ekstraksi daun kelor (Moringa oleifera)
Abstract
Moringa leaves (Moringa oleifera) contain several secondary metabolite compounds related to antibacterial, namely flavono-ids, alkaloids, saponins, terpenoids and tannins. These secondary metabolite compounds can be extracted maximally with the selection of extraction methods, solvents used and optimisation of solvent temperature and dissolving time when extracting in order to obtain good extract yields. Laboratory experimental research with maceration extraction method to see the effect of tem-perature and dissolving time on the extraction of moringa leaves. The temperature variations were T1=30±2°C, T2=40±2°C, T3=50±2°C and the time variations were t1=36 hours, t2=48 hours, t3=60 hours consisting of 3 levels with three repetitions so that 27 samples were obtained. Moringa leaf extract yield was calculated based on the weight of the sample after the extraction process against the initial powder weight of the sample. The results showed that the high yield was obtained from the extract-ion treatment at a temperature of T2=40±2°C for t3=60 hours at 4.93%. It is concluded that the solvent temperature and dis-solving time affect the amount of yield produced, the extract yield can increase followed by high temperature and longer ex-traction time until it reaches the optimal limit.
