It was carried out the phytochemical study and determination of the antiulcerous activity of Vallea stipularis L.f. “Chuillur” The species was located and gathered in the month of March of 2000, in the district of Tamburco, county of Abancay department of Apurimac, at 3100 m.s.n.m. With the powdered sample of leaves it was carried out a watery maceration. By means of a phytochemical march phenolic compound, tannins, alkaloids, steroids, saponines and carbohydrates were detected. For the chromatographic analysis in analytic finel Ayer, in preparatory scale, the system of solvents was used: CHC13 - EtOH (91), the structural elucidation was carried out for UV-visible spectroscopy and RI, four probable fractions were determined: F1: 5,7 -dihidroxi-6-metoxífiavona, F2: 5-hidroxi-7-0- glucosilfiavona, F3: p-propil phenol and F4: 2,4 dihidroxipropilbenceno. The antiulcerous activity was determined by 1971 Lee's technique, inducing gastric ulcer in stomach of Hoitman stump rat; the treatment with more effectiveness was the watery extract of leaves in a dose of 600mg/Kg; an inhibition of 62% compared with the patron group, that it obtained 18% inhibition has been observed. Vallea stípulatis L.f. “Chuillur” it presents antiulcerous activity for intragrastric route, this activity is probably due to the flavonoid presence in the watery extract of leaves. When evaluating the acute toxicity to dose limit of the watery extract of leaves in Mus musculus albinic mice species stump Balb/c, it has been determined that it doesn't produce mortality to the maximum dose of 2000mg/Kg, and in biopsy of their organs was not registered damage, for what is qualified as “Not classified.”
