1 | 2022 thesis | Investigation of antimicrobial, antioxidant and toxicity analyses of Centella asiatica as potential fresh-cut produces preservative Wong, Jun Xian Investigation of antimicrobial, antioxidant and toxicity analyses of Centella
asiatica as potential fresh-cut produces preservative were conducted. The aims of
this study are antimicrobial and antioxidant activities of C. asiatica extracts; to
determine the toxicity study of C. asiatica extract using the brine shrimp lethality
assay (BSLA) and to determine the effectiveness of C. asiatica extract as a
potential natural food additive on different types of fresh-cut fruits and vegetables
(FCFV). The antimicrobial, antioxidant and toxicity assessments of C. asiatica
extracts were then assayed based on the solvents (ethanol, methanol, water and
hexane) and investigating of total phenolic content (TPC) and total flavonoid
content (TFC). Results of objective-1 showed ethanolic extract recorded the highest
extraction yield (14.7%), TPC (69.54 mg GAE/g) and TFC (13.90 mg QE/g). The
ethanolic extract also exhibited the highest readings in disc diffusion assay (13.50
