Summary of article contents:
Introduction
Syzygium malaccense, commonly known as Malay apple or mountain apple, is a plant from the Myrtaceae family native to India and Malaysia. Its various parts, including seeds, bark, fruit, and leaves, have been utilized in traditional medicine for their therapeutic benefits. The study outlined in the article aimed to analyze the phytochemical constituents, particularly phenolics and flavonoids, in the fresh leaves of Syzygium malaccense, as well as their in vitro antioxidant activities. Antioxidants are crucial in combating oxidative stress, which impacts numerous diseases, making this research relevant for identifying potential natural sources of antioxidant compounds.
Antioxidant Activity of Syzygium Malaccense Leaf Extracts
The research findings indicated that methanolic extracts of Syzygium malaccense leaves exhibited significantly higher antioxidant activity compared to aqueous extracts. Specifically, the total phenolic content in the methanolic extract was recorded at 108.08 mg/g, while the total flavonoid content was 76.25 mg/g. These compounds are known for their radical scavenging properties. Various antioxidant assays, such as DPPH radical scavenging, hydroxyl radical scavenging, and reducing power assays, demonstrated that the methanolic extracts not only effectively neutralized free radicals but also showed more potent activity than the aqueous extracts. For instance, the IC50 value for DPPH scavenging activity was determined to be 25.74 μg/ml for the methanolic extract, indicating its strong capability to hinder oxidative processes.
Conclusion
The results of the study highlight the significant antioxidant potential of Syzygium malaccense leaves, underscoring the importance of methanolic extracts in yielding potent bioactive compounds. The findings suggest that these extracts can be further explored for their therapeutic benefits, contributing to the development of natural antioxidants in medical applications. Further investigations into the specific chemical constituents and their mechanistic actions are warranted to fully understand and harness the health benefits associated with this plant. Overall, the preliminary results represent a promising step towards the utilization of Syzygium malaccense as a natural source of antioxidants to combat oxidative stress-related diseases.
