It might result in a chronic infections that could last for years7 also,8. Medicinal plant life have been useful for the treating human diseases for a long time and has provided help for the procedure and administration of various illnesses. For this good reason, a large number of therapeutic plant life have been screened for their treatment purpose and documented in pharmacopoeias9. Hochst belongs to the family in the treatment of malaria. Although, and other medicinal plants have been used for the management of uncomplicated and resistant malaria (caused by drug Rhein-8-O-beta-D-glucopyranoside resistant strains of parasites), the mechanism of action by which combats malaria has not been explored. Although parasites have evolved quite a number of ways to develop resistance against drugs as their own means of adaptation and survival, the innate immune system of the host has been developed to overcome this evading strategy of the pathogens. With a specific immune response system, the host gets rid of many pathogens and sometimes the mechanism of action of some drugs relies on their effectiveness to boost the host immune response17. Increase in severe parasitic infections in immunocompromised patients have increased the Rhein-8-O-beta-D-glucopyranoside interest of researchers in antimalarial drug development and the possible mechanism of action of identified drugs. The interaction of anti-parasitic drugs with the immune system has long Rhein-8-O-beta-D-glucopyranoside been discovered. Orthodox antimalarial drugs such as chloroquine, pyrimethamine and quinacrine have been found to depress human polymorphonuclear neutrophils18. The antimalarial mechanism of action of some drugs have been proposed to involve their effects on the immune system, which include: interference with lysosomal acidification, inhibition of proteolysis and antigen presentation, modulation of cytokine production and inhibition of matrix metalloproteinases19. Artemisinins have been reported to have immunomodulatory properties such as inflammation, autoimmunity, and delayed-type hypersensitivity20. Specifically, they have been found to decrease the secretion of pro-inflammatory cytokines and enhance the release of Tumor Necrosis Factor (TNF), and IL-1(has been substantiated24, the activity-guided assay of its immunomodulatory effect and probable mechanism of action have not been reported. It is against this background that we reported the activity-guided assay of various solvent fractions of against malaria caused by was obtained fresh from a medicinal herb agent at the Oje Market, Ibadan, and authenticated at Ekiti State University Herbarium. A voucher (specimen number: UHAE2017/062) was deposited in the University Herbarium. The plant material was air dried, chopped into small pieces and ground into powder. It was later sieved and 400?g of the powder was soaked in 1 L absolute methanol with occasional shaking using a mechanical shaker (GFL, Germany) for 72?h. The mixture was then filtered through Whatman No. 1 filter paper and concentrated under reduced pressure using a rotary evaporator (Stuat, United Kingdom). The concentrated methanol extract was pre-adsorbed on Thin Layer Chromatography (TLC) silica gel and subject to Vacuum Liquid Chromatography. The column was eluted successively using taken may be small to elicit immediate antiplasmodial activity, compared to orthodox drugs, we may not observe significant decrease in the parasite load within 24?h. Thus, a 5 day treatment plan with 48?h interval for the assessment of parasitemia was adopted. Malaria parasites were detected in the blood after Rhein-8-O-beta-D-glucopyranoside 72?h of inoculation (day 0) and treatment commenced the same day parasites were detected in the blood (which is still day 0). To assess parasite load in the blood or the potency of the administered solvent fractions of according to the kits manufacturers protocols (Fortress Diagnostics, Rhein-8-O-beta-D-glucopyranoside Antrim, U.K). ELISA Kits (Elabscience, USA) were used to determine the levels of IL-6 (Interleukin 6), IL-1and tumour necrosis factor (TNF-likely responsible for its biological action were determined using Gas Chromatography (USA) with a coupled mass detector. The GC column analyzer has an injector set at 200?C including an ion source temperature at 250?C. The carrier gas was helium set at a flow rate of 1 1?mL/min. Essential components of the dichloromethane fraction of were detected depending on their retention times and mass fragmentation patterns that had good matches with compounds in the NIST library software. Statistical analysis The experiments were.
