Abstract: | In order to continue our previous studies concerning Geranium pyrenaicum Burm. (Geraniaceae), we have performed spectrophotometric determinations and a HPLC study of some polyphenols. We have analyzed
the dried Geranii pyrenaici herba (harvested from Cluj-Napoca, district of Cluj, Romania). We have established the content in flavonoids (0.316%), phenolic
acids (0.099%), tannins (5.295%), and anthocyanins (12.030 mg/100 g vegetal product). We have identified and measured by HPLC
the following compounds: hyperoside (21.61 μg/100 mg), ellagic acid (1810.44 μg/100 mg), isoquercitrine (11.197 μg/100 mg),
and caftaric acid (76.83 μg/100 mg). We have also analyzed by HPLC a hydrolyzed sample of the same drug in which we have identified
and measured: ellagic acid (4139.33 μg/100 mg), quercetol (29.65 μg/100 mg), kaempherol (41.48 μg/100 mg), and caftaric acid
(20.721 μg/100 mg).
