Abstract

Diabetes is a chronic disease caused by an imbalance of insulin release to the bloodstream in response to excessive glucose influx, which causes hyperglycemia. White saffron (Curcuma mangga Val.), an Indonesian aromatic spice, contains essential phytochemicals and has a number of potential health benefits. Here, we examined the effects of oral administration of white saffron powder (WSP): 1.5 and 4.5 g (WSP 1.5 and WSP 4.5) in streptozotocin (STZ)-induced diabetic rats. WSP was administered orally on a daily basis for one month and its antidiabetic, anti-inflammatory, and antioxidative effects were investigated by measuring the concentrations of blood glucose, insulin, interleukin 6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin 8 (IL-8), malondialdehyde (MDA), and superoxide dismutase (SOD) activity. In response to high WSP intervention (WSP 4.5), treated rats showed increased insulin level and SOD activity and reduced blood glucose, IL-6, IL-8, TNF-α, and MDA levels, which were closely related to the positive control (PC) group. In addition, Hematoxylin and Eosin (H&E) staining of the pancreatic tissues showed that WSP 4.5-treated rats had significant improvement in β-cell regeneration, which taken together reflected the antidiabetic potential of Curcuma mangga Val.
