	Article:	EXTRACTION EFFICIENCY OF FLAVONOIDS FROM VACCINIUM MYRTILLUS L LEAVES USING DIFFERENT EXTRACTION TECHNIQUES AND SPECTORPHOTOMETRIC QUANTIFICATION. Authors: C. COBZAC, M. MOLDOVAN, N.K. OLAH, S. GOCAN.


	Abstract: This paper studies the extraction efficiency of some flavonoids from Vaccinium Myrtillus leaves using different methods: Soxhlet extraction, microwave extraction and sonication. Each extraction technique was optimized according to characteristic parameters (extraction time, extraction solvent volume and composition of extraction system). The total flavonoid content was measured spectrophotometrically, as indicated in Romanian Pharmacopoeia (RF X). The obtained results were compared.
