摘要:
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: where R1 is ═O, —ONO, —ONO2, or —NH2; R2 is —OH, —ONO, —ONO2, or —NH2; R3 is —OH, —ONO, —ONO2. 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.
