Compared with the normal control group, the activity time of the model control group was significantly decreased (p < 0.05), and the resting time was significantly prolonged (p < 0.01), which indicated that the CUMS mouse model was successfully FIGURE 1 The effects of different dose extracts... | 683 | 251911954 | 0 | 16 |
The results of SPT, ILT, and Tail suspension test (TST) experiments indicated that the low and high-dose HCW groups display significant anti-depressive activity, and the water extracts of flowerings (HCWL and HCWH) showed better activities than that of ethanol extracts (HCEL and HCEH). In addition, the extracts of flow... | 684 | 251911954 | 0 | 16 |
Compared with the normal control group, the activity time of the model control group was significantly decreased (p < 0.05), The results of SPT, ILT and TST in the second antidepressive experiment indicated that the low and high-dose HCW groups (HCWL and HCWH) also display significant anti-depressive activity.

isolation, which was well-developed by our laboratory (Qing et al., 2016;Qing et al., 2017b), was employed. Compound 15 was obtained from HCW and its structure was unambiguously identified by NMR data. Compound 15 was obtained as a yellow amorphous powder. (Siewek et al., 1984).

total of 1205 OTUs from four groups of sequencing data of intestinal flora. As shown in Supplementary Figure S5B, four groups shared 792 OTUs. Unique OTUs were observed in the normal control (35), CUMS model control (13), FH (21), and RT (33) groups.
