3.5 | Comprehensive analysis of secondary
metabolites of A. trifoliata in rocky desertification habitat
Principal component analysis can transform many original indexes into
comprehensive indexes for analysis, which can comprehensively reflect
the response degree of plants to rocky desertification habitat.
Principal component analysis of secondary metabolites of A.
trifoliata from two bases was carried out according to the principle of
eigenvalue greater than 1 (Figure 11). The main components of Guanling
base are oleanolic acid and total phenol; The main components of Huaxi
base are flavonoids and total phenols. Comprehensive analysis showed
that the main response factor of secondary metabolites of A.
trifoliata in rocky desertification habitat was total phenol.
