Effect of Extraction and Processing Conditions on Organic Acids of Barberry Fruits

Abstract The bioactive compounds of barberry such as organic acids are widely used in medical and food industries. The effects of extraction and processing conditions including varieties (B. integerrima: A, B. vulgaris: P), solvents (water: W, ethanol: E), light (presence: L or absence: T), pH (3 and 1.5), temperatures (25 and 50C), processes of heating (at 95 and 80C), chilling (ref. 1 and 2 months), freezing (con), microwave (mic) and gamma irradiation (at doses of 0.5–10 kGy) on organic acid profile were studied. The highest (acetic, malic and ascorbic) and lowest (fumaric) amounts (mg/100g extract) of organic acids in extraction conditions were as follows: acetic in AWT325 (23,124.53 ± 747.33), malic in PET1.525 (21,035.18 ± 21.05), ascorbic in AET350 (19,796.20 ± 104.44) and fumaric in PWL325 (62.30 ± 0.45). The highest and lowest amounts of organic acids in processing conditions were as follows, respectively: acetic (Amic 17,915.07 ± 164.38) and fumaric (Acon 38.84 ± 1.44). Practical ApplicationsThe Berberis vulgaris fruit is useful as tonic for liver and heart; it prevents chronic bleeding; reduces mucus, triglycerides, cholesterol and blood pressure; and also purifies the blood. It is effective in the treatment of gallbladder, bleeding hemorrhoids, antiparasitic liver, diabetes, gout, kidney stones, colon cancer, prostate inflammation, malaria, fever, asthma and neurological diseases. Owing to its color and mellow taste B. vulga...
