BACKGROUND The efficacy and safety of Nepeta menthoides freeze-dried aqueous extract were assessed on the anxiety of patients suffering from depression. METHOD Patients received either N. menthoides formulation (400 mg/BID) or Sertraline (50 mg/BID) for 4 weeks. The Beck Anxiety Inventory (BAI) scales were used to assess the anxiety in two-week intervals (2(nd), 4(th), and 6(th) weeks). Folin...

Anti-aging cosmetics are often sought after in order to slow down the aging process. Free radicals one of main causes skin aging, and therefore antioxidants used anti-aging cosmetics. The aim this study was investigate which method is most suitable for determining antioxidant capacity these products. Having samples extracted, extracts obtained determined by following spectrophotometric methods:...

The Folin-Ciocalteu assay is a widely used method for measuring the total phenolic content (TPC) in honey, but it can be affected by presence of reducing sugars which lead to interference and an over-estimation its TPC. To optimize honey analysis, effect pH on was investigated. A number scenarios were tested using different concentrations Na2CO3 (0.00%, 0.75%, 0.94%, 7.50%) order minimize sugar...

Coffee is a major source of dietary antioxidants; some are present in the green bean, whereas others are generated during roasting. However, there is no single accepted analytical method for their routine determination. This paper describes the adaption of three complementary assays (Folin-Ciocalteu (FC), ABTS and ORAC) for the routine assessment of antioxidant capacity of beverages, their vali...

The methods most commonly used for the determination of uric acid are those of Benedict, Behre, and Folin described in almost all textbooks of clinical biochemical technique. The Folin method has been in use in this laboratory for some time, where uric acid determinations are often carried out three or four times a day on the same patient, but it was realized that this method was not sufficient...

The antioxidant capacity and antioxidant constituents of two filamentous fungi (Acremonium charticola and Rhizopus oryzae) isolated from the Indonesian fermented dried cassava (gathot) were evaluated in the present study. The antioxidant capacity of the fungal crude extracts was assessed based on the 2,2'-azino-bis(3-ethyl-benzthiazolin-6-sulfonicacid) (ABTS) method. Total phenolics were determ...

The bark of several coniferous species, a waste product of the timber industry, contains significant amounts of natural antioxidants. In our ongoing studies of Nepalese medicinal plants, we examined the bark from Abies spectabilis as the starting material for extracting antioxidant compounds. In vitro antioxidant activity evaluated by means of three antioxidant methods, namely 2,2-diphenyl-1-pi...

Abstract The hydrophilic and lipophilic antioxidant activities due to the main bioactive components present in Spanish tomato paste samples were studied, using standardized fluorescent methods. After extraction, phenolic antioxidants (Folin-Ciocalteu method) total activity (TEAC assay) evaluated, examining differences between extracts corresponding different samples. Total fluorescence spectra ...
