Isolation Of Flavonoid Compounds From Albedo Orange Red Bali (Citrus Maxima Merr.)
Unlocking the Health Potential of Orange Peel: Isolation of Flavonoid Compounds from Albedo Orange Red Bali (Citrus Maxima Merr.)
Introduction
The peel of citrus fruits, such as oranges, has long been discarded as waste, but it holds a wealth of health-promoting compounds. Among these compounds, flavonoids are a class of bioactive molecules that have been extensively studied for their antioxidant, anti-inflammatory, and anticancer properties. In this study, we aimed to isolate flavonoid compounds from the albedo (white skin) of Red Bali orange (Citrus maxima Merr.) and identify their types. Our research reveals the potential of orange peel as a source of flavonoids, which can be used to develop natural-based health and pharmaceutical products.
The Importance of Flavonoids
Flavonoids are a class of plant compounds that are known for their health-promoting properties. They are found in a wide range of fruits, vegetables, and herbs, and have been extensively studied for their antioxidant, anti-inflammatory, and anticancer activities. Flavonoids have been shown to have a range of benefits, including reducing the risk of heart disease, improving cognitive function, and reducing the risk of certain types of cancer. In this study, we aimed to isolate flavonoid compounds from the albedo of Red Bali orange and identify their types.
The Isolation Process
The isolation of flavonoid compounds from the albedo of Red Bali orange was carried out through several stages. First, maceration was carried out with methanol solvents to extract flavonoid compounds from the albedo. The methanol extract was then concentrated and dissolved in ethyl acetate until the solution became clear. The concentrated ethyl acetate extract was then dissolved in methanol. Furthermore, the methanol extract was hydrolyzed with HCl 2N. The filtrate obtained was then extracted with chloroform to get flavonoid compounds.
Purification and Identification of Flavonoid Compounds
The concentrated chloroform extract was analyzed with thin layer chromatography (TLC) and separated by column chromatography using silica gel as a stationary phase and N-hexane mixture: ethyl acetate with volume ratio (90:10) V/V, (80:20) V/V, (70:30) V/V, and (60:40) V/V as the mobile phase. The fraction obtained from a mixture of n-hexane: ethyl acetate (80:20) V/V was then purified with the Preparative and Recrystallization TLC to obtain pure compounds.
Characterization of Flavonoid Compounds
The pure compounds obtained were golden brown crystals weighing 9.2 grams, melting point 146-148 ° C, and RF value 0.72. Further identification was carried out by analysis of ultraviolet-visibel (UV-vis) spectroscopy, Fourier Transform Infra Red (FT-IR), and Proton Nuclear Magnetic Resonance (1H-NMR).
Classification of Flavonoid Compounds
Based on spectroscopic analysis, the flavonoid compounds that were successfully isolated were classified in the flavanone class. This shows that Red Bali orange peel has great potential as a source of flavanone compounds.
Pharmacological Activities of Flavanone Compounds
Flavanone is a bioactive compound that has various pharmacological activities, such as antioxidants, anti-inflammatory, anticancer, and antibacterial. Thus, isolation and identification of flavanone compounds from Red grapefruit peels opens opportunities for the development of natural-based health and pharmaceutical products.
Conclusion
This research is the first step in uncovering the health potential of Red grapefruit peels. Further research is needed to examine the pharmacological activity of the flavanone compounds obtained, as well as to examine the effectiveness and safety of their use. Our study demonstrates the potential of orange peel as a source of flavonoids, which can be used to develop natural-based health and pharmaceutical products.
Future Directions
Future research should focus on the pharmacological activity of the flavanone compounds obtained, as well as the effectiveness and safety of their use. Additionally, the development of natural-based health and pharmaceutical products using flavanone compounds from orange peel should be explored.
