It was noticed that the arachidic acid was seen only in the flower, stamens and pistils and the gadoleic acid is seen only in the stamens and pistils and allowed to consider their capacities to improve heart health, to reduce inflammation as anti-inflammatory, to improve cognitive function, to be anticarcinogenic and to be used as detergent additive. The exploitation of these chromatography phase gas analysis results permitted to give the weight concentration of the different fatty acids (mg/g) in relation to the grinded sample and in relation to the initial fresh sample for the Epiphyllum oxypetalum’s flower with stamens and pistils and for the Epiphyllum oxypetalum’s phylloclade-leaves. Then, the esterification of the Epiphyllum oxypetalum’s different parts with citric acid were carried out on a reflux assembly and followed with time reaction in order not only to extract their active molecules like flavonoids, terpénoïdes, alkaloids and fatty acids but also to determine each plant part’s kinetics parameters seeing that their quantities were in excess in comparison with the citric acid quantities. The results showed that the initial kinetic constant k for the phylloclade and stamens/pistil respectively equals to 165,000 [L2×mol-2×mn-1] and 173,844 [L2×mol-2×mn-1] were very important than for the flower without stamens and pistil equals to 39,469 [L2×mol-2×mn-1] which were certainly due to their porosities and micro-canals.
