Isolation and Identification of Phenolic Compound Groups from Large Flower Flowers of Bungur (Lagerstroemia Speciosa (L.) Press)

Introduction

Phenolic compounds are a group of compounds that have been widely studied in the field of botany and pharmacy due to their various biological activities, including antioxidant, anti-inflammatory, and anticancer properties. The large flower of the Bungur plant (Lagerstroemia speciosa (L.) Press) is a potential source of natural medicine, and its phenolic compounds have been the subject of research in recent years. This article discusses the isolation and identification of phenolic compound groups from the large flower flowers of Bungur.

Isolation of Phenolic Compounds

The isolation of phenolic compounds from the large flower flowers of Bungur was carried out through several stages of systematic extraction and analysis. The first stage involved the extraction of the plant material using methanol solvents. The concentrated methanol extracts were then dissolved again using ethyl acetate, and this process was repeated until the solution showed negative results, indicating that all compounds that could be extracted with ethyl acetate had been taken. The ethyl acetate extracts were then concentrated and dissolved in methanol, and partitioned using N-HEXANA. The methanol extract was then analyzed using thin layer chromatography (TLC) and separated using column chromatography with a mixture of chloroform-ethyl acetate solvents in ratios 30:70, 20:80, and 10:90 (V/V).

Characterization of Isolated Compounds

The isolation results showed that the compound obtained was in the form of greenish yellow solids weighing 8.6 mg and had a RF value of 0.62 in chloroform-ethyl acetate 30:70 (v/v) solvents. The UV-VIS spectrum analysis showed the maximum absorption peak at the wavelength (λmax) 275 nm on the band I and 218 Nm in the band II. The FT-IR spectrum indicated the presence of functional groups such as OH, C-H, C = O, ester, C = C Aromatic, C-H SP3, and C-O. Further analysis using Proton Nuclear Magnetic Resonance (1H-NMR) identified the existence of Proton H-2 and H-6, protons from CH3 which are bound to benzene rings, as well as protons from metoxy. Based on the interpretation of the data, the isolated compounds were identified as phenolic compounds included in the phenolic acid group, which is thought to be methyl gallate.

Analysis of Phenolic Compounds

Phenolic compounds are groups of compounds that are widely known in the world of botanical and pharmacy. They have a variety of useful biological activities, such as antioxidant, anti-inflammatory, and anticancer properties. The existence of phenolic compounds in large flower flowers shows the great potential of this plant as a source of natural medicine.

Methyl Gallate, which is suspected as an isolated compound, has many health benefits. Research shows that methyl gallate functions as a strong antioxidant that can protect cells from damage caused by free radicals. In addition, this compound is also associated with inhibition of cancer cell growth, making it an interesting research subject in the development of anti-cancer drugs.

Importance of Analysis Methods

The use of appropriate analysis methods, such as chromatography and spectroscopy, is very important in determining the identity and characteristics of isolated compounds. This method provides accurate information about molecular structures and chemical interactions, which are very useful in pharmacognosy research and herbal products development.

Conclusion

Research on large Bungur plant flowers not only enriches understanding of phenolic compounds, but also opens opportunities for further exploration of the use of this plant in modern medicine. This knowledge is very important to support the development of safe and effective herbal products.

Future Directions

Further research is needed to fully understand the potential of the large flower flowers of Bungur as a source of natural medicine. This includes the isolation and identification of other phenolic compounds, as well as the study of their biological activities and potential applications in medicine.
