Piper chaba, Antidiabetic, Antilipidemic, Antibiofilm


Objectives: Piper chaba, native to South and Southeast Asia, has been traditionally used as a medicinal plant. Aim of this study was to evaluate the antihyperglycemic and antihyperlipidemic activities of P. chaba root extracts (RE) in streptozotocin (STZ)-induced diabetic rats along with its antimicrobial activity.

Methods: Diabetes was induced in Wister rats through the intraperitoneal administration of STZ (50 mg/kg b.w.). Antidiabetic and antilipidemic activities of the RE (in methanol, ethanol, ethyl acetate and distilled water) were evaluated by administering oral dose (200 mg/kg b.w.) for 21 days. Metformin (12.1 mg/kg b.w.) was used as a positive control. Blood samples of rats were drawn by tail vein puncture and cardiac puncture to determine the fasting blood glucose (FBG) and serum level of total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL), respectively. Standard protocols were followed to determine the antimicrobial and antibiofilm activities against two different strains of bacteria.

Results: Oral administration of P. chaba RE for 21 days resulted in a significant (p< 0.001) decrease in FBG and TC, TG, and LDL levels (p<0.001), when compared to the untreated diabetic rats. Significant (p<0.001) increase of HDL was observed when ethyl acetate and aqueous RE were administered. Out of four, two extracts showed varying antimicrobial activities, particularly against the gram-positive bacteria. 

Conclusion: It became evident for the first time that P. chaba extracts possess antimicrobial activities and can serve as biochemical compounds with great alternative therapeutic potential in the management of diabetes and hypercholesterolemia.
