- •
QAMS may be more effective and practicable than normal external standard method.
- •
The verified QAMS could be an alternative and promising method for quality control.
- •
The inherent quality was distinct between the extracts from different origins.
- •
Hierarchical cluster analysis and canonical discriminant analysis were employed.
- •
Taguchi Design was introduced to evaluate the fluctuations and applicability of QAMS.
