UHPLC-MS and GC-MS phytochemical profiling, amelioration of pain and inflammation with chloroform extract of Funaria hygrometrica Hedw. via modulation of inflammatory biomarkers.

People of Pakistan have undisturbed customs for the employment of medicinal plants for healthcare requisites. Chloroform extract of F. hygrometrica (CE FH) was examined for its ability to reduce inflammation and to produce analgesia. Carrageenan and formalin-induced paw edema model for inflammatory activity, hot-plate and tail-flick methods to assess analgesic activity were executed. Phytochemical analysis was done by UHPLC-MS and GC-mass spectrometer. The results demonstrated that in carrageenan-induced paw edema, maximum reduction in inflammation was observed at 5th hour at the dose 100 mg/kg; while at doses 250 and 500 mg/kg, maximum response was observed at 5th and 6th hours. Analgesic activity results indicated that maximum analgesia was observed up to 120 min at 100 mg/kg, while up to 90 min in case of 250 and 500 mg/kg doses. The formalin-induced rat paw edema showed significant (p < 0.05) anti-inflammatory activity after 5 days treatment. After, testing period of 10 days, the biochemical parameters such as CBC, CRP, serum enzymes like CAT, SOD, GSH and inflammatory mediators like TNF-α, IL-6, IL-4 and IL-10 were estimated. The administration of formalin resulted in an increase in the level of leucocytes, total WBC, CRP, serum enzymes and in the diameters of paw thickness, while pre-treatment with CE FH at dose levels of 100, 250 and 500 mg/kg exhibited a diminution in the levels of SOD, GSH, CAT, total RBC and HB. Acute inflammatory mediators such as TNFα, IL -6 and IL-4 were reduced, and IL-10 was upregulated in the treated group as compared to the control. Many phytoconstituents, i.e., chitobiose, chlorovulone III, γ-tocotrienol, emmotin, cassine, hexacosanedioic acid, neophytadiene, fumaric acid, neophytadiene, hexadecanoic acid, phytol and stigmasterol were detected during UHPLC-MS and GC-MS analysis seems to be responsible for the said activity in correlation with the already reported data about these compounds. The results concluded that CE FH possess noteworthy anti-inflammatory and central analgesic action at different doses (100, 250 and 500 mg/kg).

Metabolic Profiling of Heliotropium crispum Aerial Parts Using HPLC and FTIR and In Vivo Evaluation of Its Anti-Ulcer Activity Using an Ethanol Induced Acute Gastric Ulcer Model.

This study explored the antiulcer potential of methanol extract and fractions of Heliotropium crispum roots against the ethanol-induced gastric ulcer model in rats. Metabolic profiling of H. crispum aerial parts using Fourier-transform infrared spectroscopy (FTIR) revealed the presence of different metabolites with various functional groups. Meanwhile, High Performance Liquid Chromatography (HPLC) revealed the presence of three main peaks assigned to myricetin, quercetin, and kaempferol. In vivo, antiulcer activity results showed that the disease control group displayed five tiny ulcers less than 2 mm in diameter in addition to two hemorrhagic streaks. However, in the standard control group, only one small ulcer was visible for the total methanol extract. Gastric tissues and contents were evaluated to determine many parameters such as ulcer score, ulcer index, percentage inhibition of ulcer, gastric pH, gastric juice volume, and acidity. Results were endorsed by histopathological evaluation; gastric pH and mucus content were significantly increased, but gastric juice volume was significantly decreased. All fractions showed a significant decrease in ulcer index and % inhibition except the n-hexane fraction, whose results were insignificant compared to the disease control group. Thus, it was concluded that H. crispum shows an antiulcer effect by decreasing gastric juice volume and acidity, whereas gastric pH and mucus contents were increased that is attributed to the synergistic action of its detected polyphenolic compounds.
