Among the herbal drugs currently studied flavonoids occupy a prominent position due to its broad spectrum of therapeutic activities already demonstrated. This work was possible to obtain a fraction rich in flavonoids species Camptosema coriaceum Benth, a Leguminosae. Through the technique of HPLC-DAD-MS was possible to isolate and identify six flavonoid glycosides. Rutin, a glycoside well known was elected as a marker of flavonoid-enriched fraction, this was quantified and its validation method was established. The results showed that the analytical methodology developed for the quantification of rutin is accurate, reproducible and linear over the concentration range 8-48 mg / ml of rutin (R = 0.99943). In order to make this flavonoid-enriched fraction as a technological product, was performed the encapsulation of molecules in β-cyclodextrin rutin and antioxidant tests were made of the material encapsulated and unencapsulated, to evaluate the efficiency of the method pharmaceutics. It was observed that when encapsulated rutin has reduced its antioxidant activity. Additionally, biological tests lymphoproliferation on various carcinoma cell lines were conducted with the crude extract of the species C. coriaceum, with the fraction enriched in flavonoids and rutin, being the most active crude extract.
