TL;DR

This study used laboratory techniques and computational modeling to analyze flavonoids from Centella asiatica leaf extracts.

Full summary

387 CHARS

Qualitative analysis indicated high flavonoid and phenolic content in ethanol and methanol fractions. BDE calculations suggested that the 4′-OH site in both flavonoids had the lowest energy, indicating strong hydrogen atom donation capacity, with castilliferol's 4′-OH being lower than castillicetin's. ADME analysis suggested castilliferol has fewer violations as a potential drug lead.

ABSTRACT

Abstract Centella asiatica (CA) is a medicinal plant widely used in the East, with many of its phytoconstituents remaining unexplored. In this study, compounds were extracted and identified from C. asiatica to determine its medicinal properties. Phytochemical screening was conducted on shoot, callus, and cell suspension extracts, revealing the presence of tannins, flavonoids, terpenoids, saponins, and steroids in all three cultures, with no alkaloids detected. IC50 values were determined to evaluate the antioxidant activity of the extracts, with the highest value observed for cell suspension culture (20 µg/mL), followed by shoot culture (19 µg/mL), and then callus extract (10 µg/mL), with ascorbic acid as the standard at an IC50 value of 26.25 µg/mL. Finally, density functional theory was used to analyze the structure–activity relationships of the identified compounds from C. asiatica extract. The results suggest that ultrasonic-assisted extraction yielded the highest recovery and antioxidant activity, with a scavenging activity of 79%. This study provides valuable insights into the phytochemical composition and antioxidant potential of C. asiatica , which may have implications for its use in traditional medicine and future drug development. Keywords: C. asiatica , GC-MS, antioxidant activity, density functional theory, molecular docking
