This research studied the extraction of active ingredients from the Nagoya and female weasel salet leaves. The objective is to find the main ingredient in extracting flavonoids group with solvent ethanol, 95%, and oil. For extraction, fermentation, with 95% ethanol, which has studied the extraction period. 1 day 3 days include a 5-day and 7-day 7-day period, which is the amount of extract (crude extrac). Oil extraction methods for the study case is extracted by heat and heat if heat. A study in the period of 3 days, and 7 days of fermentation. It found that the extraction of all cases, the amount of extract (oil extrac) is similar, but different characteristics of color, which found that the extraction using heat to a darker color, if you don't use the heat clearly. Tests found that extract crude chemical properties classified as phenolic compounds at oil extract non-phenolic acid compounds from the crude extract come noi nofla volume vo. Ya Nang leaf extract found to the servo นอย์ greater than leaf extract nofla salet weasel females.
