| Sumario: |
The phytochemical standardization of hydroalcoholic extracts of Ishpingo Ocotea
quixos Lam. KOSTERN consisted in evaluating the influence of three experimental
variables: plant material (fresh and dry), solvent (ethanol and cane ethanol) and solvent
concentration (90, 70, 50) % v/v through an experimental factorial design which one
we obtained 12 different extracts with 3 repetitions of each of them. A phytochemical
screening showed the presence of phenols, tannins, catechins, saponins, quinones,
coumarins, lactones and alkaloids in the 36 extracts; we used the Folin - Ciocalteu
method in order to quantitatively determine the total phenol concentration and by
statistical analysis ANOVA (Tukey 95%) proves that there is significant difference
between the 12 established treatments where the extracts with the mayor quantity of
phenols are AMF50:50 (Alcohol, Fresh Material, Concentration 50% v/v) and
CMF90:10 (Cane alcohol, Fresh Material, Concentration 90% v/v) with 12,538 and
13,298 mg of gallic acid / mL of extract respectively; concluding that, this last
combination allows to obtain greater quantity of total phenols following the
established standardized protocol. |
