The Antioxidant Polysaccharide from Semiaquilegia adoxoides (DC.) Makino Adjusts the Immune Response of Mice Infected by Bacteria. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:2719483. [PMID: 32148535 PMCID: PMC7049844 DOI: 10.1155/2020/2719483] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/07/2019] [Revised: 09/11/2019] [Accepted: 01/24/2020] [Indexed: 01/19/2023]
Abstract
Semiaquilegia adoxoides (DC.) Makino is a herbal medicine and it is recorded that its water extract can be used to treat acute diseases caused by bacterial infections. In order to understand the polysaccharide of Semiaquilegia adoxoides (DC.) Makino (SMP), FT-IR and HPLC methods were performed to determine the basic chemical structure and monosaccharide compositions of SMP. The antioxidant capacity of SMP was analyzed by monitoring both the scavenging rate of DPPH and ABTS free radical. To investigate the effects of SMP on the acute bacterial disease, minimum inhibitory concentrations (MICs) of SMP on E. coli or S. aureus were detected; meanwhile, mice were administrated with SMP for 7 days and then infected with E. coli or S. aureus, and the parameters were measured at the 9th day. Results showed that SMP was a furanose which was mainly composed of glucose (60.3%) and had certain antioxidant activities. Both MIC values of SMP on E. coli and S. aureus were 250 ml/mL, which means that SMP has no direct antibacterial effects. The mice experiments revealed that SMP had potential effects on immunomodulatory by reducing WBC and the expression of serum IL-1, IL-6, and TNF-α and increasing IgM of E. coli or S. aureus infected mice. These findings supported the effect of Semiaquilegia adoxoides (DC.) Makino in folk use with scientific evidence.

Protective effects of Semiaquilegia adoxoides n-butanol extract against hydrogen peroxide-induced oxidative stress in human lens epithelial cells. PHARMACEUTICAL BIOLOGY 2016; 54:1656-1663. [PMID: 26974044 DOI: 10.3109/13880209.2015.1113993] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/16/2015] [Revised: 08/05/2015] [Accepted: 10/25/2015] [Indexed: 06/05/2023]
Abstract
Context Hydrogen peroxide (H2O2)-induced damage in the lens epithelium leads to cell death and cataract. Semiaquilegia adoxoides (DC.) Makino (Ranunculaceae), a folk medicine of Hmong (an ethnic group of China), has been traditionally used to treat cataract; however, the underlying molecular mechanism is yet to be uncovered. Objective This study aimed to investigate whether the n-butanol extract of S. adoxoides (nSA) is effective against the H2O2-induced oxidative stress in human lens epithelial (HLE) cells. Materials and methods Human lens epithelial (SRA 01/04) cells were stimulated by H2O2 (250 μM) in the presence or absence of nSA. The antioxidant effects of nSA were determined in terms of cell viability (MTT assay), apoptosis (AnnexinV/PI staining), radical scavenging capability (various enzymatic assays), loss of mitochondrial membrane potential (Rhodamine 123 staining), expression of apoptotic markers including caspase-3 and caspase-9 and the change of Bcl-2/Bax ratio (western blot) in the HLE cells. Results The results showed that pretreatment of nSA (250, 500 and 1000 μg/mL) markedly reduced H2O2-induced cellular apoptosis and malondialdehyde accumulation, but elevated the activities of total superoxide dismutase, catalase, glutathione peroxidase. Thus, the total antioxidative capability was enhanced upon the nSA treatment meanwhile the loss of mitochondrial membrane potential was prevented. Moreover, nSA at concentrations of 250, 500 and 1000 μg/mL also significantly suppressed the activation of caspase-3 and -9, and increased the Bcl-2/Bax ratio in the HLE cells. Discussion and conclusion Our findings suggested that nSA is a potential prophylactic agent in the prevention of cataractogeneis.

Mining chemodiversity from biodiversity: pharmacophylogeny of medicinal plants of Ranunculaceae. Chin J Nat Med 2016; 13:507-20.

Abstract
This paper reports a pharmacophylogenetic study of a medicinal plant family, Ranunculaceae, investigating the correlations between their phylogeny, chemical constituents, and pharmaceutical properties. Phytochemical, ethnopharmacological, and pharmacological data were integrated in the context of the systematics and molecular phylogeny of the Ranunculaceae. The chemical components of this family included several representative metabolic groups: benzylisoquinoline alkaloids, ranunculin, triterpenoid saponin, and diterpene alkaloids, among others. Ranunculin and magnoflorine were found to coexist in some genera. The pharmacophylogenetic analysis, integrated with therapeutic information, agreed with the taxonomy proposed previously, in which the family Ranunculaceae was divided into five sub-families: Ranunculoideae, Thalictroideae, Coptidoideae, Hydrastidoideae, and Glaucidioideae. It was plausible to organize the sub-family Ranunculoideae into ten tribes. The chemical constituents and therapeutic efficacy of each taxonomic group were reviewed, revealing the underlying connections between phylogeny, chemical diversity, and clinical use, which should facilitate the conservation and sustainable utilization of the pharmaceutical resources derived from the Ranunculaceae.

Abstract
Through bioassay-guided fractionation, thirteen compounds (1-13) were isolated from the dry root of Semiaquilegia adoxoides, known as Tiankuizi in traditional Chinese medicine (TCM). Among these, four benzoic acid derivatives (1, 2, 4, 5), one 4,6-dimethoxy-5-methyl-2 H-pyran-2-one (10) and one 1,2,3-propanetriol (13) were found for the first time in S. adoxoides. This is the first record of compound 10 from a natural source. 4-Hydroxybenzoic acid (1) and 3,4-dihyroxybenzoic acid (2) showed selective inhibition against elastase release and superoxide anion generation, with IC50 values of 3.20 and 6.21 μg/mL, respectively. Compound 1 had 7-fold better activity than the positive control against elastase release induced by human neutrophils. Overall, our studies demonstrated Tiankuizi (S. adoxoides) as a potential TCM and isolates 1 and 2 as promising lead compounds for neutrophilic inflammatory diseases.

Abstract
Inflammatory bowel disease (IBD) affects the mucosal lining of the gastrointestinal tract; the etiology is unknown and treatment is directed at systemic immunosuppression. Natural products, including medicinal herbs, have provided approximately half of the drugs developed for clinical use over the past 20 years. The purpose of our current study was to determine the effects of a novel combination of herbal extracts on intestinal inflammation using a murine model of IBD. Female Swiss-Webster mice were randomized to receive normal water or 5% dextran sulfate sodium (DSS) drinking water to induce colitis. Mice were treated with either a novel combination of herbal aqueous extracts or vehicle control per os (po) or per rectum (pr) every 24 hours for 7-8 days. Disease activity index score (DAI) was determined daily; mice were sacrificed and colons were analyzed by H & E staining, MPO assay, and cytokine (TNF-alpha, IL-6) ELISAs. Mice treated with the combination of herbal extracts, either po or pr, had significantly less rectal bleeding and lower DAI scores compared to the vehicle-treated group. Moreover, colonic ulceration, leukocytic infiltration, and cytokine levels (TNF-alpha and IL-6) were also decreased in the colons of herbal-treated mice, reflected by H & E staining, MPO assay, and cytokine ELISA. Treatment with the combination of medicinal herbs decreases leukocyte infiltration and mucosal ulceration, ameliorating the course of acute colonic inflammation. This herbal remedy may prove to be a novel and safe therapeutic alternative in the treatment of IBD.
