Ajuga bracteosa (Ab) has tremendous medicinal value with long-established disease curing potential. The present study aimed to assess the hepatoprotective potential of Ab extracts in paracetamol-induced hepatotoxicity in mice. Group I (normal control) were treated with saline 1 ml/kg BW orally for 7 days while Group II (toxicant control) received saline 1 ml/kg BW for 6 days and Paracetamol (1000 mg/kg BW) on day7of the treatment. Group III received Standard drug silymarin (100 mg/kg BW) for 6 days and Paracetamol (1000 mg/kg BW) on day 7of treatment. Groups IV andV were administered with methanol extract (ME) 200 mg/kg BW and aqueous extract (AE) 1000 mg/kg BW for 6 days and Paracetamol (1000 mg/kg BW) on day 7th of the study. Both extracts showed hepatoprotective potential against the toxic effects of paracetamol, evidenced by serum analysis of biomarkers involved in liver injury and histopathological findings. Hepatotoxic mice pretreated with Ab plant extract or silymarin exhibited significant decrease in ALP, AST, and ALT enzyme level while GSH levels were markedly increased. According to histological observations, groups treated with PCM (toxicant control) showed significant necrosis and lymphocyte infiltration, while groups treated with silymarin and Ajuga bracteosa plant extract showed preservation of the normal liver structural features. The phytochemical analysis of ME and AE of Ab showed the presence of glycosides, phenolic compounds, tannins, fats, saponins, flavonoids, terpenes, oils, and fats. The antioxidant activity of these two extracts was determined by nitric oxide assay, DPPH assay, and ferric reducing power assay. The methanolic extract exhibited the highest antioxidant potential (78.09 ± 0.0806). The antioxidant potential of aqueous extract was 73.08 ± 0.248. The reducing power for methanolic extract and ascorbic acid (standard) 500 μg/ml was 0.933 and 0.987 respectively. The anti-inflammatory activity of both extracts was demonstrated by in vitro methods, namely albumin denaturation, proteinase inhibition, and membrane stabilization assays. The study suggests that Ab extracts have competence for attenuating inflammation, oxidants, and hepatotoxicity.

Antioxidant-rich fraction of Amomum subulatum fruits mitigates experimental methotrexate-induced oxidative stress by regulating TNF-α, IL-1β, and IL-6 proinflammatory cytokines.

The culinary spice Amomum subulatum was assessed for its phytochemical composition, in vitro antioxidant potential, and in vivo ameliorating effect against methotrexate (MTX)-induced toxicities. Phytochemical analysis of methanolic extract of A.subulatum dry fruits (MEAS) confirmed the presence of different bioactive secondary metabolites. MEAS scavenged reactive free radicals and inhibited lipid peroxidation in vitro. To confirm the antioxidant efficiency of MEAS, in vivo experiment was carried out in which MTX was administered to induce oxidative stress. Co-administration of MEAS reduced MTX-induced hepatic, renal, and pulmonary toxicities via significantly (p<.01) enhancing antioxidant status and reducing oxidative stress. MTX treatment significantly (p<.01) increased liver and kidney toxicity markers and increased proinflammatory cytokine (TNF-α, IL-1β, and IL-6) levels. However, co-administration of MEAS significantly (p<.01) reduced their levels, and tissue histopathology confirmed the protective effect of MEAS in maintaining normal tissue architecture following MTX treatment. Protective effect of MEAS is accredited to the antioxidant and anti-inflammatory properties exhibited by bioactive compounds in MEAS. PRACTICAL APPLICATIONS: Amomum subulatum (Black cardamom) is a folkloric and culinary spice used for its organoleptic, nutritional, and medicinal properties. This study demonstrated the phytochemical composition and antioxidant potential of methanolic extract of A.subulatum dry fruits (MEAS). Toxicities associated with MTX therapy limit its clinical application. MEAS attenuated methotrexate-induced oxidative stress, inflammation, and associated organ damages, suggesting the possible therapeutic application of A.subulatum in reducing oxidative stress and associated diseases. Our results showed that A.subulatum is a potential functional food, which may be used for the betterment of health due to its richness in antioxidant and anti-inflammatory phytochemicals.
