Abstract
Background/Objectives: Modern people pay attention to the antioxidant effects that protect human aging and damage, but active ingredients used in cosmetics or pharmaceutical raw materials of synthetic ingredients are exposed to a number of problems.
 Methods/Statistical analysis: An alternative method for solving the problem was selected, and Ginkgo biloba Leaves (hereinafter GBL) and Acer palmatum Leaves (hereinafter APL) were selected to compare and analyze antioxidant efficacy evaluations such as total polyphenol, total flavonoid, DPPH ability, ABTS radical scavenging ability, and FRAP activity measurement.
 Findings: In the results of the study, GBL and APL showed DPPH activity at all concentrations (㎍/㎖). ABTS activity and FRAP Value also showed antioxidant activity in both GBL and APL, and in particular, APL has been found to be potent and is considered a rich antioxidant.
 Improvements/Applications: ABTS activity and FRAP Value also showed antioxidant activity in both GBL and APL, and in particular, APL has been found to be more potent. Therefore, these species can be evaluated as rich antioxidants. This study hopes to provide GBL and APL extracts as data for the development of natural antioxidants in cosmetics and pharmaceuticals.
Highlights
Because modern people are threatened with health due to excessive stress on their busy daily life and work, interest in disease prevention and physiological efficacy is increasing
After Ginkgo biloba Leaves and Acer palmatum Leaves were extracted with reflux for three hours after adding two liters of distilled water to 120 g of each, the filtered liquid is concentrated with rotary vacuum evaporator, and the concentrated liquid was dried with a freeze dryer
Mg QE/g in APL was found to be much higher than GBL which showed 17.38±5.09 mg QE/g (Table 1)
Summary
Because modern people are threatened with health due to excessive stress on their busy daily life and work, interest in disease prevention and physiological efficacy is increasing. Free radicals have been reported to cause molecular modifications associated with several degenerative diseases such as atherosclerosis, diabetes, asthma, Parkinson's, Alzheimer's, and immunodeficiency disease. Based on these previous studies on antioxidants, this study compared and analyzed antioxidant efficacy evaluations of GBL and APL such as total polyphenol and total flavonoid, DPPH and ABTS activity, and FRAP activity measurement. Throughout this study, we aim to provide the basic data for GBL and APL to be developed for natural antioxidants in cosmetics or pharmaceutical ingredients
