- Abstract
- Ajwa대추 열매(DF)와 종자 Ajwa대추 열매(DFS)는 많은 건강상의 이점이 있는 페 놀 화합물의 중요한 공급원입니다. 자유 라디칼 중화에 있어 DF와 DFS의 잠재력을 조사하기 위해 100% 에탄올, 70% 에탄올, 뜨거운 물 추출물의 세 가지 방법으로 추출한 결과 항산화제와 페놀 화합물의 양.
실험 연구에서 플라보노이드를 함유한 3가지 추출물 모두 항산화 활성이 있는 것으로 관찰되었으며, 이 활성은 농도 측면에서 각 추출물과 다른 추출물 사이에 차이가 있음을 알았습니다. 하이드록실 라디칼 패밀리에서의 활성 DPPH 뿌리 및 ABTS에 의한 항산화 테스트를 사용할 때.
또한 이들 추출물의 페놀화합물 함량이 서로 다른 것으로 나타났으며, 열수추출 물(DF1)의 페놀화합물 함량이 최대 3008.66μg/g으로 가장 높았다.
본 연구를 통해 Ajwa대추야자의 열매와 종자는 약간의 생물학적 활성을 보인 천 연화합물 측면에서 수익률이 좋다고 할 수 있으며, 효능과 활성면에서 차이가 나는 경우에는 좋은 것으로 볼 수 있다. 화장품의 성분.|Ajwa date fruit (DF) and Ajwa date fruit seed (DFS) are essential sources of phe- nolic compounds with many health benefits. To investigate the potentials of DF and DFS in neutralizing free radicals, they were extracted by three different methods: 100% ethanol, 70% ethanol, and hot water extract, and the results showed a difference be- tween them in terms of the effectiveness of antioxidants and the number of phenolic compounds.
In the experimental study, it was observed that all three extracts containing flavonoids had antioxidant activity, and found that this activity differed between each extract in terms of concentration, where the 100% ethanolic extract of the seeds (DFS3) showed the most significant activity in the hydroxyl radical family, when using antioxidant assay DPPH and ABTS.
It was also found that these extracts had different amounts of phenolic compounds, and the hot water extract of the fruit (DF1) recorded the highest content of phenolic compounds, up to 3008.66 μg/g.
This study shows that the fruits and seeds of the Ajwa date palm have a good re- turn in terms of natural compounds that showed some biological activities, and although they differ in terms of effectiveness and activity, they can be considered a good component of cosmetic products.
