Study Notes

Cardioactive Glycosides

Cardioactive glycosides are a group of compounds found in plants with effects on the heart
These glycosides are composed of two parts: a sugar (glycone) and a non-sugar (aglycone or genin)
The aglycone is responsible for the pharmacological activity while the sugar influences the pharmacokinetic properties
The pharmacological activity is mainly focused on their ability to:
- Increase the force of heart contraction
- Slow down the heart rate - Negative Inotropic effect

Experiment No. 1:

This experiment focuses on extracting and identifying cardioactive glycosides from plant samples
The aim is to separate the two parts of the glycoside (sugar and non-sugar) and then identify each
Two fractions are collected: "Fraction A" contains the complete glycoside and "Fraction B" contains only the genin部分
