Glycemic Index of Longan Syrup in Healthy Volunteers

March 17, 2020 updated by: Pornanong Aramwit, Pharm.D., Ph.D, Chulalongkorn University

Determination of Glycemic Index of Longan Syrup in Healthy Volunteers

Volunteers take 50 g of glucose in 250 ml of water in 5 minutes.Then, they are tested blood glucose levels (taken from the fingertips) at 15, 30 ,45, 60, 90, and 120 minutes. There is 3 days for wash out period. These tests will be repeated for 3 times for baseline glucose calculation. After that, volunteers take 50 g of longan syrup in 250 ml of water in 5 minutes.Then, they are tested blood glucose levels (taken from the fingertips) at 15, 30 ,45, 60, 90, and 120 minutes. Glycemic index of longan syrup is calculated from area under the curved of blood glucose after longan syrup taking divided to mean of area under the curved of blood glucose after glucose taking.

EXPERIMENTAL: Glucose and Longan syrup
Volunteers take 50 g of glucose in 250 ml of water in 5 minutes.Then, they are tested blood glucose levels (taken from the fingertips) at 15, 30 ,45, 60, 90, and 120 minutes. There is 3 days for wash out period. These tests will be repeated for 3 times for baseline glucose calculation. After that, volunteers take 50 g of longan syrup in 250 ml of water in 5 minutes.Then, they are tested blood glucose levels (taken from the fingertips) at 15, 30 ,45, 60, 90, and 120 minutes. Glycemic index of longan syrup is calculated from area under the curved of blood glucose after longan syrup taking divided to mean of area under the curved of blood glucose after glucose taking
Dietary supplement: Glucose and Longan syrup
Volunteers take 50 g of glucose in 250 ml of water in 5 minutes. Then, they take 50g of longan syrup in 250 ml of water in 5 minutes
