Antioxidant and Elastase, Tyrosinase, α-Glucosidase Inhibitory Effects of Five Types of Mint Extracts

Abstract

Purpose: This study evaluated the biological activity of five types of mints (Peppermint, Spearmint, Chocomint, Applemint, Pineapplemint).Methods: Five types of mints were extracted with an ethanol solvent to compare the total polyphenol and total flavonoid content, scavenging activities of DPPH and ABTS radical, SOD-like activity, and inhibitory effects of elastase, tyrosinase, and α-glucosidase.Results: All five types of mint extracts were confirmed to be effective significantly in concentration. The total polyphenol content was found to be effective in the order of peppermint>spearmint>chocomint>pineapplemint>applemint, and the total flavonoid content was found to be effective in the order of peppermint> chocomint>spearmint>pineapplemint>applemint. The DPPH radical scavenging activity was found to be in the order of peppermint>spearmint>chocomint> pineapplemint>applemint, and the ABTS radical scavenging activity was found to be in the order of peppermint>chocomint>spearmint>pineapplemint>applemi nt. The SOD-like activity was found to be in the order of peppermint>chocomint> spearmint> pineapplemint>applemint. The inhibitory effects of elastase, tyrosinase, α-glucosidase were found to be in the order of peppermint>spearmint>chocomint> pineapplemint>applemint.Conclusion: As above results, all five types of mint extracts were verified to be effective significantly in concentration. In particular, peppermint indicated the highest total polyphenol, total flavonoid, DDPH and ABTS radical scavenging activity, and SOD-like activity, while chocomint displayed the highest tyrosine, elastase, and α-glucosidase inhibitory effects.

A Study on Antioxidant and Anti-inflammatory of Salvia microphylla Ethanol Extract

“…Salvia microphylla 차는 전통적으로 복통과 설사와 같은 위장 문제를 치료하고 불면증 치료에 사용되어왔다 (Jenks & Kim, 2013;Pérez-Nicolás et al, 2018). 부인과 질병에 사용되었으며 (Jenks & Kim, 2013), 항산화 (Cha et al, 2009), 항종양제 (Mathew & Thoppil, 2012) 항박테리아, 리파아제 억제제, 유리라디칼 억제 제 (Villa-Ruano et al, 2013), 살충효과 (Zavala-Sánchez et al, 2013;Romo-Asunción et al, 2016)…”

Development of Anti-aging Cosmetics Using Chitosan/ γ-Cyclodextrin/Fucoidan Nanoparticles (Nanogel) Based on the Drug Delivery System

“…양성대조군으로 사용된 BHT의 경우 18.08,35.22,56.26,69.19,75.21,83.28%로 확인되었다(Figure 2B). 대 표적인 항산화 물질의 양성대조군과 비교하여 결과가 유의미함을 나 타낸다 (Um & Ryu, 2022). 후코이단 단독보다는 키토산/감마-사이 클로덱스트린/후코이단의 ABTS radical 소거능이 더 높게 확인되었 으며 나노 입자가 더 빠른 항산화 반응을 일으키는 것으로 사료된다.…”
