METHOD AND APPARATUS FOR THE QUANTITATIVE DETERMINATION OF TOTAL LACTONES IN ANDROGRAPHIS PANICULATA

摘要

A METHOD APPARATUS AND APPARATUS FOR DETERMINING QUANTITY OF LACTONES IN ANDROGRAPHIS PANICULATA ARE DISCLOSED.THE METHOD AND APPARATUS INITIALLY INVOLVE COMBINING A TEST SAMPLE CONTAINING ANDROGRAPHIS PANICULATA AND A MATRIX SOLUTION TO FORM A FIRST SOLUTION OBTAINED THROUGH LEACHING ACTIONS.THE METHOD AND APPARATUS THEN INVOLVE COMBINING THE FIRST SOLUTION AND A COLOUR DEVELOPING CHEMICAL TO FORM A SECOND SOLUTION.THE APPARATUS AND METHOD FURTHER INVOLVE COMBINING THE SECOND SOLUTION AND AN ALKALINE SOLUTION TO FORM A THIRD SOLUTION THROUGH IONIC REACTION, THE THIRD SOLUTION DEVELOPING A COLOUR.MORE SPECIFICALLY, THE COLOUR OF THE THIRD SOLUTION IS OBSERVABLE TO DETERMINE THE AMOUNT OF LACTONES IN THE TEST SAMPLE CONTAINING ANDROGRAPHIS PANICULATA.
