The present invention relates to methods and strategies for extracting nitrosylated and/or nitrated derivatives and analogs from Myrciaria dubia fruit and for synthesizing the same. The ascorbic acid derivatives and analogs have the chemical structure of: ##STR00001##
where R.sub.1 is O, ONO, ONO.sub.2, or NH.sub.2; R.sub.2 is OH, ONO, ONO.sub.2, or NH.sub.2; R.sub.3 is OH, ONO, ONO.sub.2. The extraction method comprises freeze-drying the Myrciaria dubia fruit, mixing the freeze-dried powder with a solvent and separating and drying the supernatant. The synthetic method comprises derivatizing an ascorbic acid via nitrosylation and/or nitration in a buffered ascorbic acid solution, reducing zero or more nitro groups to an amine group, and purifying the ascorbic acid analog.
