FIGURE 8 C4H activity of A. trifoliata in different
habitats
3.4 | Effect of rocky desertification habitat
on medicinal ingredients content in A. trifoliata
It can be seen from Figure 9 that with the growth and development ofA. trifoliata , the oleanolic acid content in roots, stems and
leaves first increased and then decreased, and the content of oleanolic
acid in roots > leaves > stems. At the same
time, the increasing rate of oleanolic acid content in rocky
desertification habitat was faster, and the content was significantly
higher than that in normal habitat. In Guanling base, the difference of
roots was the biggest in October, increased by 1.45 times, the
difference of stem in October was the largest, increased by 1.92 times,
and the difference of leaves in June was the largest, increased by 1.26
times; In Huaxi base, the difference of root was the biggest in
September, increased by 1.17 times, stem was the biggest in October,
increased by 1.69 times, leaf was the biggest in June, increased by 1.25
times. In conclusion, the content of oleanolic acid in roots, stems and
leaves of A. trifoliata could be increased in rocky
desertification habitat.
