ABSTRACT
In this research work, one of Myanmar well known fruits, Fragaria × ananassa Duch., Myanmar name Strawberry was selected to qualify and quantify the flavonoids present in it. The fresh Strawberries were collected from Pyin Oo Lwin Township, Mandalay Region, Myanmar. Firstly, the fresh Strawberries were crushed to obtain the expressed juice with distilled water which is the liquid product. This juice was checked for qualitative test of flavonoids. It responds positive for Ferric Chloride test, Shinoda’s test and Lead Acetate test respectively. In addition, total flavonoid content of Fragaria × ananassa Duch. was evaluated by the Aluminum chloride (AlCl3) method using UV spectrophotometer (UV- 1800, SHIMADZU, UV spectrophotometer) at 415 nm. The total flavonoid content of this selected sample was determined as 45.37±0.25 mg quercetin equivalent (QE) per 100 g fresh weight.
Key words: Fragaria × ananassa Duch., Strawberry, flavonoids Aluminum chloride (AlCl3) method, quercetin, UV spectrophotometer.
