Artemisinin (ART) is an oral antimalarial agent with poor aqueous solubility and low oral bioavailability. The present study describes the preparation of artemisinin with polyethylene glycol (PEGs 1500, 4000 and 6000) as a solid dispersion to increase the solubility of artemisinin. Solid dispersion of the drug were pr…

A new phenomenon was observed for p-men- thane-1,2,4-triol, i.e., the substance with the same molecular structure occurs in two forms with different polarity. The form with a lower polarity is eluted with ethyl acetate in column chromatography; the form with a higher polarity is eluted with methanol. The crystals isol…

In this paper we introduce and investigate an interesting subclassMK (k) (;h ) of functions which are analytic in the punctured unit disk and meromorphically close-to-convex. By using the principle of subordination, we establish several properties such as inclusion rela- tionship and distortion theorems for functions…
