Objective To compare differences in the pharmacological activities of Angelica sinensis and its components on hematopoietic and laxative effects. Methods Kunming mice were randomly divided into eight groups,with 12 mice in each group consisting of equal numbers of males and females. These groups included a normal group,a model group, a positive group, a Angelica sinensis(AS)group, an Angelica sinensis water-soluble (AW)group, an Ethanol extract of Angelicae sinensis(AE) group, and an Angelica sinensis essential oil(AO) group. Except for the normal group, all other groups were established as blood deficiency constipation mouse models through subcutaneous injection of N-acetylphenylhydrazine combined with oral administration of loperamide hydrochloride. On the 7th day of modeling, each group received oral administration of the respective test substance once daily for three consecutive days. General condition and body weight changes of the mice were observed, peripheral blood cells were counted, stool morphology and fecal output were recorded, fecal moisture content and colonic tissue moisture content were determined, small intestine propulsion rate was assessed by a charcoal meal method, and serum levels of β-endorphin (β-EP), cholecystokinin octapeptide (CCK-8), substance P (SP), and vasoactive intestinal peptide (VIP) were determined by ELISA. Differences in the pharmacological activities of Angelica sinensis and its components on hematopoietic and laxative effects were analyzed. Results Compared with the normal group, model group mice showed significantly reduced white blood cell ( WBC), red blood cell (RBC), hemoglobin ( HGB), hematocrit (HCT), and platelet (PLT) counts, and body weight (P<0. 05 or P<0. 01). Additionally, fecal moisture content,colon moisture content, and small intestine propulsion rate were decreased (P<0. 05 or P<0. 01) and serum CCK-8and SP levels were also lower (P<0. 01), while serum β-EP and VIP levels increased (P<0. 05). Compared with the model group, AS and AW groups had higher WBC, RBC, HGB, HCT, and PLT counts, defecation volume, fecal moisture content, and colon moisture content (P<0. 05 or P<0. 01). The AE group showed increased WBC, RBC,HGB, HCT, and PLT counts, and colon moisture content (P<0. 05 or P<0. 01), but defecation volume and fecal moisture content were not significantly altered. The AO group exhibited increased fecal moisture content, colon moisture content, and defecation volume (P<0. 05 or P<0. 01), but no significant changes in WBC, RBC, HGB,HCT, and PLT counts. The AE group showed no significant changes in defecation volume, fecal moisture content,and colon moisture content. The AS and AO groups had increased small intestine propulsion rates (P<0. 01), while there was no significant difference in small intestine propulsion rate between the AW and AE groups. The AS group had elevated serum CCK-8 and SP levels (P<0. 01) and decreased serum β-EP and VIP levels (P<0. 01). The AO group had increased serum CCK-8 and SP levels ( P<0. 05), but no significant change in serum β-EP and VIP levels. The AW group had decreased serum VIP levels (P<0. 05), but no statistically significant difference in serum CCK-8 and SP levels. Compared with the AS group, the AW group had higher WBC, RBC, HGB, HCT, and PLT counts, while the AO and AE groups had lower levels of these parameters (P<0. 05). Both AW and AO groups had increased fecal moisture content (P<0. 05), and both AW and AE groups had increased colon moisture content ( To compare differences in the pharmacological activities of Angelica sinensis and its components on hematopoietic and laxative effects.

Both AW and AO groups had increased fecal moisture content (P<0. 05), and both AW and AE groups had increased colon moisture content (P<0. 05). AO, AE, and AW groups had elevated serum CCK-8 and SP levels and decreased serum β-EP and VIP levels (P<0. 05 ). In summary, the groups were ordered as follows: AE > AO > AS > AW in terms of blood replenishment, AO> AS > AW > AE in terms of promoting bowel movements, and AO > AS > AE > AW in terms of intestinal motility. Conclusions Angelica sinensis and its components have varying degrees of blood replenishing and bowel-promoting activities. The AE component has strong blood replenishing activity, while the AO component has strong bowel-promoting and defecation-stimulating activity. These findings provide a reference for the development of traditional Chinese medicines based on Angelica sinensis components.
