title: [Standardization of the sour orange flower and leaf].
abstract: Dried flowers (1 batch) and leaves (6 batches) of sour orange Citrus aurantium L. had a similar flavonoid pattern. But the flavonoid levels of flowers were higher than those of leaves. The mean levels of the principal flavonoid compounds were respectively: total flavonoids 12.35 and 1.06%, neohesperidin 5.44 and 0.08%, naringin 1.93 and 0.06%, eriocitrin 0.38 and 0.25%. 18 batches of commercial origine were also examined for a comparative study. Specifications were proposed for a revision of the monographs "Sour orange flower" and "Sour orange leaf" of the French Pharmacopoeia.
