Introduction: Alpinia galanga Linn. belongs to the family Zingiberaceae has been used as a traditional medicine in China for relieving stomach ache, treating cold, invigorating the circulatory systems, diabetes, and reducing swelling.

Aim: To evaluate the antidiabetic activity of methanolic extract of A.

Antidiabetic activity of ethanolic extract of Cyperus rotundus rhizomes in streptozotocin-induced diabetic mice.

Objective: In the present investigation, ethanolic extract of Cyperus rotundus (EECR) rhizomes was evaluated for antidiabetic activity in streptozotocin (STZ)-induced diabetic swiss mice.

Materials And Methods: After administration of EECR extract for 3 weeks, the body weight, blood glucose, biomarker enzymes (serum glutamic pyruvic transaminase [SGPT] and serum glutamic oxaloacetic transaminase [SGOT]), and plasma lipid levels were measured in STZ-induced diabetic mice.

Results: The ethanolic extract at dose levels of 250 and 500 mg/kg body weight revealed significant antidiabetic activity, improvement in body weight, and reduction in elevated biochemical parameters such as SGPT, SGOT, cholesterol, and triglyceride levels.

Pharmacognostical evaluation of aerial parts of Graptophyllum pictum (L.) Griff. (Syn: Justicia picta Linn.): A well-known folklore medicinal plant.

Objective: Graptophyllum pictum (L.) Griff. (Family-Acanthaceae) occupies a key role in traditional system of medicine.

Pharmacognostical study and establishment of quality parameters of aerial parts of Costus speciosus-a well known tropical folklore medicine.

Objective: To evaluate the diagnostic pharmacognostical characters of Costus speciosus (aerial parts) along with their physico-chemical parameters and fluorosence analysis.

Method: The pharmacognostical characters were determined in terms of macroscopy, microscopy, powder microscopy, leaf constant, fluorescence analysis and preliminary phytochemical investigation.

Results: The findings of macroscopy revealed that leaves elliptic to oblong or oblong-lancoelate, thick, spirally arranged, with stem clasping sheaths up to 4 cm, flowers large, white, cone-like terminal spikes, with bright red bracts.
