국내산 대나무 잎 유기용매 추출물의 항산화 활성 및 성분 분석

Abstract

Bamboo extract contains large amounts of polyphenols and flavone glycosides as natural antioxidants. It is known that the types of polyphenols and fatty acids contained in each type of bamboo are different, and the antioxidant activity is also different. This study analyzed the antioxidant activity and functional component analysis of domestic bamboo (Phyllostachys pubescens and Sasa coreana Nakai) leaf extracts. An oil extract was prepared from Phyllostachys pubescens and Sasa coreana Nakai using an organic solvent (n-hexane, chloroform:methanol). Antioxidant activity, total polyphenol content (TPC), and total flavonoid content (TFC) of the prepared oil extract were measured. Gas chromatography-mass spectrometry (GC-MS) analysis was performed to confirm the components contained in the oil extract. As a result of the experiment, it was confirmed that the yield of chloroform:methanol was the highest, and the yield of the hexane extract was meager. It was confirmed that the DPPH and ABTS activities of the SC-C extract were the highest, while those of the IC50 were 1,064.21 μg/mL and 437.35 μg/mL, respectively. TPC and TFC were also confirmed to have the highest SC-C extract contents, which were 45.27 and 74.32, respectively. As a result of GC/MS analysis, it was confirmed that the types contained differed depending on the extracted solvent. This study confirmed the possibility of using bamboo leaf oil extract as a cosmetic material.
