The study of some polyphenolic compounds from Melissa officinalis L. (Lamiaceae).
We proposed the analyses of polyphenolic coumpounds from the Melissa officinalis L. (Lamiaceae) leaves obtained from Medicinal Plant Collection of USAMV Cluj-Napoca.


METHODS
The study was performed by using spectrophotometric (I) and HPLC methods (II).


RESULTS
The vegetal product contains 0.64% flavonoids expressed in rutoside and 8,962% phenyl-propane derivatives expressed in caffeic acid (I). HPLC analyses (II) were made after extraction of studied compounds from leaves with ethyl-ether, ethyl acetate and 1-buthanol. These extracts were analyzed before and after the hydrolysis of compounds. There were identified 6 polyphenolic compounds: caftaric acid, caffeic acid, p-cumaric acid, ferulic acid, luteolin and apigenin.


CONCLUSIONS
The extracted amount of these compounds in chosen solvents depending of their polarity.
