Saluyot Mechanism of action in disease treatment and prevention
Phenolic antioxidants from the leaves of Corchorus olitorius L.
Corchorus olitorius leaves contains six phenolic antioxidative compounds The contents of these phenolic compounds, were determined, and their antioxidative activities were measured using the radical generator-initiated peroxidation of linoleic acid. The results obtained showed that 5-caffeoylquinic acid was a predominant phenolic antioxidant in Corchorus olitorius leaves. Source: Journal of Agricultural Food Chemistry. (1999 Oct)
Gastroprotective effects of Corchorus olitorius (Saluyot leaf extract)
A study aimed to evaluate the gastroprotective effect of an ethanolic extract of Corchorus olitorius against ethanol-induced gastric ulcers in adult Sprague Dawley rats showed that sambong extract posses gastroprotection in the experimental groups and medical benefits were comparable to that of the reference control medicine omeprazole.

Corchorus olitorius (jute) extract induced cytotoxicity and genotoxicity on human multiple myeloma cells (ARH-77).
A study investigated cytotoxic and genotoxic effects of leaf extracts (LE) and seed extracts (SE) of the Corchorus olitorius on the multiple myeloma-derived ARH-77 cells. Results have showed that both Saluyt leaf and seed extracts exerted cytotoxic effects on cells and the results of the comet assay revealed that the extracts induced genotoxic damage on ARH-77 cells. The leaf and seed extract treatments indicated that genotoxic damage significantly increased with increasing concentrations at relevant cytotoxic concentrations. Source: Pharmaceutical Biology.

Polyphenolic compounds with anti-tumour potential from Corchorus olitorius (L.)
Chromatographic fractionation of the methanolic extract of Corchorus olitorius (L.) yielded two polyphenolic compounds. The compounds when tested possess mild cytotoxic activity which was significant against HeLa cells at ⩾800μM. The plant Corchorus olitorius therefore represents a potential source of natural 'lead' compounds with anti-tumour potential. Source: Bioorganic & Medicinal Chemistry Letters. (2016 Aug)
Health Benefits of Saluyot for Diabetes
A study conducted in Department of Biochemistry and Nutrition, India reported that by administering powdered Saluyot supplements to pregnant rats, both the mother and the fetus exhibited an increased resistance in diabetes induced oxidative stress versus a control group. The results suggest that Saluyot supplementation during pregnancy may provide beneficial effects against diabetes induced oxidative stress both for the mother and the fetus. (Journal of Diabetes. March 2013: Dietary supplementation with Ipomoea aquatica attenuates maternal and fetal oxidative stress in streptozotocin-diabetic rats)
Anti-inflammatory and antipyretic properties of Corchorus olitorius aqueous extract
A study was conducted to determine the antipyretic and anti-inflammatory effects of Corchorus olitorius root in Wistar rats. The results showed that Corchorus olitorius root extract (p<0.05) decreased the elevated temperature and inflammation compared with the control group.This study suggests that Corchorus olitorius root is another good source of phytomedicine that can be used effectively to treat inflammation and pyrexia that accompany some diseases.

Helath Benefits of Saluyot Against Liver Disease
The Department of Molecular Medicine, University of Malaya in Malaysia conducted a study on the protective action of Saluyot against thioacetamide-induced hepatotoxicity in rats to determine if Saluyot can indeed help treat jaundice. An ethanol extract of Saluyot has been administered to rats subjected to liver damage by thioacetamide. Results had shown that the rats when compared to a control group showed resistance against liver lesions, cell necrosis and inflammation.
The study further suggests that the protective effect of Saluyot extract in chemical-induced liver damage might be contributed to its modulation on detoxification enzymes and its antioxidant and free radical scavenger effects. Moreover, it confirms a scientific basis for the traditional use of Saluyot for the treatment of liver disorders.
