Poly(l-lactic acid) (PLLA) fiber mats containing two types of crude Garcinia mangostana Linn. (GM) extract [i.e., dichloromethane extract (dGM) and acetone extract (aGM)] were successfully prepared by electrospinning process. Both the neat and the GM-loaded PLLA fibers were smooth, with the average diameters ranging between 0.77 and 1.14 mu m. The release characteristics of GM from the GM-loaded PLLA fiber mats were carried out by total immersion method in acetate buffer or simulated body fluid that contained 0.5 % v/v Tween 80 and 3 % v/v methanol (hereafter, A/T/M or S/T/M medium) at either 32 or 37 A degrees C, respectively. The maximum cumulative amounts of GM released from the GM-loaded PLLA fiber mats in the S/T/M medium were greater than those in the A/T/M medium. Moreover, the cumulative amounts of GM released from the aGM-loaded PLLA fiber mats were greater than those from the dGM-loaded PLLA fiber mats in both types of medium. The antibacterial activity of the dGM-loaded PLLA fiber mats was greatest against Staphylococcus aureus DMST 20654, while that of the aGM-loaded PLLA fiber mats was greatest against S. aureus ATCC 25923 and S. epidermidis. Lastly, only the dGM-loaded PLLA fiber mats at extraction ratio of 10 mg mL(-1) were toxic to the human dermal fibroblasts.
