Preliminary Phytochemical Screening and Antioxidant Activity on Fruits of Amomum subulatum Roxb. No Ko Soe May Phyoe Thynn This research deals with the investigation of the biochemical properties, nutritional value and antioxidant activity of fruits from Amomum subulatum Roxb. belonging to the family Zingiberaceae. The fruit specimens were collected from Kachin State, Myitkyina District, Sadone Township at the altitude of (2000) M.A.S.L in July 2024. The preliminary screening analysis of the dried powdered fruits from A. subulatum Roxb. revealed the presence of the phytochemical elements such as alkaloids, steroids, terpenoids, glycosides, phenolic compounds, flavonoids, tannins, saponins, α-amino acid, proteins, reducing sugars, starch, and carbohydrates. Cyanogenic glycosides were not found in this study. The nutritional composition of A. subulatum Roxb. fruits were evaluated for moisture, total ash, crude fat, crude fiber, crude protein, carbohydrates, and energy content. The antioxidant activity of A. subulatum Roxb. was determined by 1,1-diphenyl-2-picrylhydrazl (DPPH) radical scavenging assay with different concentrations of watery fruit extracts. The result showed very strong antioxidant activity of fruits of A. subulatum Roxb. as indicated by a low IC50 value of 11.9 ppm (11.9 μg/ml). In conclusion, the fruits of A. subulatum Roxb. demonstrated the potential therapeutic properties although further research is needed. This study was believed to contribute to the development of natural drugs, food industries using as spices and to provide scientific evidence supporting these applications. 2025-03-03 https://meral.edu.mm/records/12739
