Abstract

1 page of the number 1 page summary of the invention The extraction process of Lee extract from teak leaves by fermentation method with a single solvent. This talks about the process Prepared extract of teak leaves by fermentation with a single solvent. Starting from the collection of tattoo leaves By pruning at In the lower part of the trunk And choose a tattoo that is fully grown They were dried at a temperature of 50-60 degrees Celsius for a period of 24 hours, grinding the leaves into powder. Extraction by fermentation with a single solvent (Solvent extraction) using solvents, namely hexane, ethyl acetate, methanol, water, water mixed with methanol with a ratio of 1 0.25 - 5. Part, water mixed with ethanol with a ratio of 1: 0.25 - 5 parts in the ratio of 1 kg of dry powder per 5-20 liters of solvent, filtered to obtain a clear extract. And dried For use in production Natural color additives from the tattoo leaves The teak leaf extract obtained from this preparation has many shades, including orange, sugar, orange sugar. Red and red brown sugar:
