Phenolic Profiles

Several extraction parameters were tested to determine optimal conditions for extracting phenolics from leaves and stems of red clover ( Trifolium pratense L. cv. Kenland), with the goal of using extracts in bioassays and in assessment of phenolic profiles. HPLC-UV profiles were compared before and after partitioning a methanolic extract of soluble phenolics with ethyl acetate-ethyl ether (1:1, v/v). The effect of extract pH on the partitioning of phenolics into the ethyl acetate-ethyl ether (EtOAc-Et2O) phase was evaluated, and several tissue weights were extracted to determine a minimum amount that could be extracted without loss of information. HPLC profiles of soluble phenolics were similar in the methanolic extracts and the partitioned EtOAc-Et2O extracts. However, recoveries in unpartitioned extracts were 2- to 4-fold greater than in the acidified, partitioned extracts. Also, recovery was considerably affected by the pH to which extracts were adjusted prior to partitioning. In extracts acidified to pH 2, recoveries were 2- to 7-fold higher than in extracts partitioned at pH 6. In extracts prepared from 250, 120, or 60 mg of tissue, peak areas of methanolic extracts were directly proportional to the amount of tissue extracted.
