The leaves ofIlex kudingchaare used as an ethnomedicine in the treatment of symptoms related with diabetes mellitus and obesity throughout the centuries in China. The present study investigated the antidiabetic activities of an active components group (ACG) obtained fromIlex kudingchain alloxan-induced type 2 diabetic mice. ACG significantly reduced the elevated levels of serum glycaemic and lipids in type 2 diabetic mice. 3-Hydroxy-3-methylglutaryl coenzyme A reductase and glucokinase were upregulated significantly, while fatty acid synthetase, glucose-6-phosphatase catalytic enzyme was downregulated in diabetic mice after treatment of ACG. These findings clearly provided evidences regarding the antidiabetic potentials of ACG fromIlex kudingcha. Using LC-DAD/HR-ESI-TOF-MS, six major components were identified in ACG. They are three dicaffeoylquinic acids that have been reported previously, and three new triterpenoid saponins, which were the first time to be identified inIlex kudingcha. It is reasonable to assume that antidiabetic activity ofIlex kudingchaagainst hyperglycemia resulted from these six major components. Also, synergistic effects among their compounds may exist in the antidiabetic activity ofIlex kudingcha.

Effects of green macroalgae 55% ethanolic extract Enteromorpha prolifera through an ultrafiltration membrane of 3 kDa (EPE3k) on antidiabetic activity, gut microbiota, and regulation mechanism were investigated in high-fat/high-sucrose diet and streptozocin-induced diabetic mice. The structural characterizations of its major compounds in EPE3k were determined by ultra-performance liquid chromatography-quadrupole/time of flight mass spectrometry. Furthermore, the intestinal microflora modulation in diabetic mice was also investigated with high-throughput 16S rRNA gene sequencing. The proposed presence of polyphenols in EPE3k was confirmed. EPE3k could significantly decrease the fasting blood glucose and improve fasting glucose tolerance. The hypoglycemic effect of EPE3k was via activation of phosphatidylinositol 3-kinase and suppression of c-Jun N-terminal kinase in liver. EPE3k treatment significantly increased the relative abundance of Akkermansia and decreased the proportion of Alistipes and Turicibacter. The above results indicated that EPE3k could be provided as a new potential therapy for the treatment of type 2 diabetic mellitus.

Diabetes mellitus is a chronic metabolic disorder and rapidly increasing cases of diabetes throughout the world are major concerns in both developed and developing countries. Currently available oral antidiabetic medicines have limitations in efficacy and safety, which in conjunction with the emergence of diabetes mellitus as a global epidemic have aided the popularity of alternative therapies to manage the disease safely and more efficiently. Herbal medicines are accepted as alternative therapies for blood sugar control. Gymnema sylvestre, Boerhavia diffusa, Tinospora cordifolia, and Argyreia nervosa are some potent herbs used for the management of diabetes. Mixing of these plants in different ratios may produce synergistic antidiabetic actions which may have greater antidiabetic activity. Hence, the present study aimed to determine the anti-diabetic activities of polyherbal extracts in streptozotocin-nicotinamide induced type 2 diabetic mice. The administration of polyherbal extract orally at doses of 100, 200 and 400 mg/kg significantly decreased the blood glucose levels compared to the control diabetic mice. The polyherbal extract significantly lowered the elevated total cholesterol, triglycerides and low-density lipoprotein levels, while increased the high-density lipoprotein indicating antihyperlipidemic activity. The present study reveals that polyherbal extract at a dose of 400 mg/kg body weight resulted in a significant decline (p < 0.001) in blood glucose level.
