ABSTRACT
Fatty acids in the Malania oleifera oil of Yunnan were esterified by sulfuric acid-methanol and analyzed by GC-MS. Seventeen components were separated and seven acids as methylesters were identified and determined. They were hexadecanoic acid (1.50%), 9c-octadecenoic acid (21.54%), 11c-eicosenoic acid (7.04%), 13c-docosenoic acid (18.29%), docosanoic acid (1.33%), 15c-tetracosenoic acid (40.92%), tetracosanoic acid (2.14%). There were 7.24% components unidentified.

A 3-month clinical investigation was undertaken to evaluate a population of premium reusable daily wear soft contact lens wearers when refitted with soft contact lenses worn on a daily wear schedule and replaced every 2 weeks. In addition to an initial visit, follow-up visits occurred at 2-, 4-, 8-, and 12 weeks. Areas of assessment included vision, lens fitting performance, ocular physiology, subjective comfort and handling responses and lens surface deposits and damage. Of the 51 patients recruited, 50 were successfully trial fit and enrolled. During the course of the investigation, all subjects utilized a multipurpose care regimen without the addition of an enzymatic cleaner. Upon conclusion of the investigation, 75.0 percent of the subjects chose to continue wearing the study lenses on a 2-week frequent replacement basis.
