Chromatographic profiles of extractives from leaves of Eugenia uniflora

ABSTRACT Eugenia uniflora L., Myrtaceae, popularly known as “pitanga”, is used in traditional medicine due the properties attributed to its chemical content, these being mainly hydrolysable tannins and flavonoids. This study provides a qualitative and quantitative evaluation of chemical profile from leaves of E. uniflora. The HPLC analysis was carried out on a C18 column (4.6 mm × 250 mm, 5 µm) by gradient elution with methanol and water (acidified with trifluoracetic acid); and silica gel Plates 60-F 254 with 10–12 µm and 5–6 µm particles, respectively for TLC and High HPTLC analy...
