Abstract

Objective: To analyze and evaluate the total alkaloid content of different parts of Magnolia officinalis from Jinggangshan. Methods: The total alkaloids of trunk, branch skin, root bark, flowers, leaves from the same plant were determined by using perchloric acid titration, and the contents of different parts of the plant and processed product were compared. Results: The total alkaloid contents of each part were 4.6053 ± 0.0814, 5.4734 ± 0.1047, 6.5940 ± 0.0715, 7.9546 ± 0.0686, 7.2220 ± 0.0776 mg/g respectively. The alkaloid content of processed products was lower than that of the fresh. Conclusion: The alkaloid content of the flowers was the highest in the same plant of Magnolia officinalis, but the lowest for the traditional part trunk. It was suggest that the fresh Magnolia officinalis should be used as medicine.
