Abstract

Nigella A, also named Sieboldianoside A, has been extracted from many kinds of Traditional Chinese Medicine (TCM), such as Nigella glandulifera, Stauntonia chinensis DC., and the leaves of Acanthopanax sieboldianus. Nigella A exhibited potential analgesic, anti-inflammatory, anti-tumor, and antioxidant activities. However, whether Nigella A could treat ulcerative colitis (UC) is still unknown. As saponins always be regarded as the kinds of ingredients that could regulate immunity and intestinal flora. This research aimed to investigate the therapeutic effect of Nigella A on UC and explore its effect on intestinal flora. We noted that Nigella A and Sulfasalazine (SASP) could significantly improve the signs and symptoms, alleviate colonic pathological injury in DSS-induced mice. The changing of many specific bacterial genus such as Lactobacillus, Porphyromonadaceae, Bacteroides and Escherichia might closely related to the recovery of intestinal inflammatory response. This study initially confirmed the therapeutic effect of Nigella A and SASP on DSS-induced colitis by improving the diversity of intestinal microbial composition. Nigella A has the potential to be developed for the treatment of UC and other disorders related to the imbalance of intestinal flora.
