Key Takeaway
Note that matrine and oxymatrine show promise in preclinical models by reducing inflammation and histopathological scores.

This meta-analysis synthesized data from 13 preclinical studies to evaluate the effects of matrine or oxymatrine monotherapy on ulcerative colitis in animal models. The analysis focused on histopathological scores, inflammatory cytokines (TNF-alpha, IL-6, IL-1beta), and markers of oxidative stress (MDA, SOD activity).

Key findings include a significant reduction in histopathological scores (effect size -3.47; 95% CI: -4.83 to -2.11) and a decrease in Disease Activity Index (DAI) at 3 days (-2.92) and 7 days (-4.76). Additionally, the meta-analysis reported significant reductions in TNF-alpha (-2.88), IL-6 (-2.91), and IL-1beta (-2.73) levels, alongside a reduction in MDA levels (-3.06) and an increase in SOD activity (2.63). Colon length increased by 2.09 (95% CI: 1.55 to 2.64).

The authors note that the indirect comparison of oxymatrine versus matrine should be interpreted cautiously. While these results suggest potential as multi-target therapeutic agents for ulcerative colitis, the evidence is limited by its preclinical nature. Clinical translation requires further high-quality studies to confirm these findings in human populations.

How this fits prior evidence

This meta-analysis of animal models addresses a gap in understanding the mechanisms of specific compounds like matrine and oxymatrine. While prior coverage noted that combined TCM and conventional medicine therapies show higher overall effectiveness than monotherapy in ulcerative colitis, this study specifically evaluates the potential of these agents as multi-target therapeutic options.

Living with ulcerative colitis means dealing with constant inflammation and damage to the digestive tract. Researchers are looking for ways to calm this internal fire, and a recent review of 13 studies suggests that two compounds, matrine and oxymatrine, might help.

In these animal models, both treatments were linked to lower scores for tissue damage and reduced levels of inflammatory markers like TNF-alpha and IL-6. The study also noted improvements in colon length and body weight, suggesting a protective effect on the gut. These compounds appear to work by targeting multiple pathways at once.

It is important to remember that these results come from preclinical animal studies, not from human clinical trials. While the findings are encouraging for potential future treatments, we do not yet know how these substances perform in humans or what their safety profile looks like in people. More high-quality research is needed before these can be considered as medical options.

What this means for you:
Matrine and oxymatrine show promise in reducing inflammation in animal models of ulcerative colitis.

Common questions

What did the study find about these treatments?

The analysis of 13 studies showed that matrine and oxymatrine reduced histopathological scores, which measure tissue damage. They also lowered levels of inflammatory markers like TNF-alpha, IL-6, and IL-1beta while increasing SOD activity, which helps protect cells from damage.

How did the treatment affect physical symptoms in the models?

In the animal models studied, the treatments were linked to a decrease in the Disease Activity Index at 3 and 7 days. Additionally, the subjects showed an increase in body weight and colon length compared to the control groups.

Can I use these compounds to treat my ulcerative colitis?

These results come from preclinical animal models, not from human trials. Because these substances have not been tested in humans yet, you should speak with your doctor about current approved treatments for your specific condition.

BackgroundMatrine and oxymatrine are bioactive alkaloids from Sophora species with reported anti-inflammatory and antioxidant effects in ulcerative colitis (UC). However, their overall efficacy has not been systematically evaluated.MethodsDatabases including PubMed, EMBASE, Web of Science, Scopus, CNKI, Wanfang, VIP, and SinoMed were searched to January 2026. Animal studies using matrine or oxymatrine monotherapy in UC models were included. Effect sizes were calculated as standardized mean differences (SMDs) with 95% confidence intervals (CIs).ResultsThirteen studies were included. Compared with controls, matrine-type alkaloids significantly reduced histopathological scores (SMD = −3.47, 95% CI: −4.83 to −2.11) and decreased Disease Activity Index (DAI) at 3 days (SMD = −2.92, 95% CI: −4.27 to −1.57) and 7 days (SMD = −4.76, 95% CI: −6.30 to −3.23), but not at 14 days (SMD = −1.01, 95% CI: −2.22 to 0.20). Body weight increased at 7 days (SMD = 2.76, 95% CI: 1.95–3.57) and 14 days (SMD = 2.41, 95% CI: 0.12–4.69), and colon length was also increased (SMD = 2.09, 95% CI: 1.55–2.64). Matrine-type alkaloids reduced TNF-α (SMD = −2.88, 95% CI: −3.50 to −2.26), IL-6 (SMD = −2.91, 95% CI: −4.64 to −1.17), IL-1β (SMD = −2.73, 95% CI: −4.27 to −1.19), and MDA levels (SMD = −3.06, 95% CI: −4.47 to −1.65), while increasing SOD activity (SMD = 2.63, 95% CI: 1.37–3.89). Subgroup analyses suggested generally similar directions of effect across species and model types. The pooled effect estimate appeared larger in the oxymatrine subgroup than in the matrine subgroup, but this indirect comparison should be interpreted cautiously.ConclusionMatrine-type alkaloids may exert protective effects in UC animal models by improving histological damage, reducing disease activity, and modulating inflammatory and oxidative stress pathways. These findings suggest their potential as multi-target therapeutic agents, although further high-quality studies are required for clinical translation.Systematic Review Registrationhttps://www.crd.york.ac.uk/PROSPERO/view/CRD420261376235, identifier CRD420261376235.
