Abstract

Objective To compare the changes of chemical components of Hedysari Radix (HR) before and after honey-processing, and to explore the material basis of the difference between HR and honey-processed Hedysari Radix (HPHR) in Buzhong Yiqi. Methods Different compounds in aqueous extracts of HR and HPHR were analysed by UPLC-MS. A rat model of spleen qi deficiency was established. The rats were treated with different doses of water extracts of HR or HPHR, and pathological differences in spleen tissue, serum levels of D-xylose, gastrin (GAS) and amylase (AMS) interleukin-2 (IL)-2 and tumour necrosis factor-α (TNF-α), as well as spleen and thymus indices, were used as indicators. Differences in the efficacy of HR and HPHR in Buzhong Yiqi were studied. Results The research showed that compared with the blank group, the spleen tissue of rats in the model group showed spleen tissue damage, which mainly manifested as unclear boundaries between red pulp and white pulp, irregular spleen morphology and irregular arrangement, and the structure of white pulp destruction, less lymphocytes, the number of germinal centers decreased or atrophied. Compared with the model group, the middle and high dose groups of HR and HPHR had protective effects on spleen tissue of spleen-qi deficiency rats, and HPHR had a stronger effect; compared with those in the model group, rats in each treatment group showed remarkably higher serum D-xylose, GAS and AMS levels and thymus and spleen indices, and remarkably lower serum IL-2 and TNF-α levels, among which HPHR group showed better regulation effect than HR group. A total of 16 differential compounds were found in the aqueous extracts of HR and HPHR, of which 10 compounds in HPHR were up regulated, while 6 compounds were down regulated compare to HR. Conclusion The results indicated that both HR and HPHR can improve spleen qi deficiency syndrome of rats, the pharmacodynamic effect of the latter was better than the former. Differences in components of HR and HPHR potentially leading to variations in efficacy.

Highlights

Hedysari Radix (HR) is the dried root of the leguminous Hedysarum polybotrys Hand.-Mazz., which has been extensively used as a traditional Chinese medicine (TCM) for thousands of years
IL-2 and tumour necrosis factor-α (TNF-α) Test Results. e results in Table 4 show that serum IL-2 and TNF-α levels in the model group were significantly higher than those in the blank group (P < 0.01)
Qi deficiency leads to insufficient defensive qi, which, in turn, reduces the resistance of the body to the invasion of external evils and causes disease. us, qi deficiency reduces immune functions. e spleen is the largest immune organ of the human body and plays an important role in regulating the immune functions of the body

Summary

Introduction

Hedysari Radix (HR) is the dried root of the leguminous Hedysarum polybotrys Hand.-Mazz., which has been extensively used as a traditional Chinese medicine (TCM) for thousands of years. It is the same as Astragali Radix in clinical application [1]. Honey-processed Hedysari Radix (HPHR) is the honeyprocessed form of HR in TCM, which exhibits effects of tonifying middle and replenishing qi, and is commonly used for the treatment of fatigue, poor appetite and diarrhoea [2]. Buzhong Yiqi, one term of TCM treatment principle, refer to treat spleen qi deficiency by improving spleen function. Processing herbal medicine is a classic characters of TCM clinic. e TCM theory holds that processing with
