Passiflora alata Dryander

Nota de alcance

PARTE UTILIZADA= Used part: Hojas.

ACCIÓN FARMACOLÓGICA= Pharmacological action: Calmantes, diuréticas, emenagogas.

COMPOSICIÓN QUÍMICA= Chemical composition: Extracts of leaves from Passiflora alata presented Cglycosyl flavonoids isovitexin (0.018 mg/mL) and vitexin (traces) together with other unidentified major flavonoid compounds. The method was subjected to recovery assay, determining its reproducibility. A remarkable difference in flavonoid concentration was observed for leaves collected in different seasons (summer and winter), and its flavonoid profile is different from P. incarnata. The three spectrophotometric methods tested to determine the total flavonoid content presented many differences in the values found. Recently, saponins have been described for P. alata as additional compounds that can contribute to its pharmacological effects [32].

ZONA GEOGRAFICA= Geografical zone: América tropical, Brasil.

DIVERSIDAD GENÉTICA Y MEJORAMIENTO DE PLANTAS MEDICINALES= Medicinal plants and improvement of medicinal herbs:

Sweet passion fruit (Passiflora alata Curtis) is gaining importance in the in natura fruit market due to differential value. Genetic breeding is crucial to improve crop quality and productivity. Molecular markers of DNA have been very useful by allowing obtaining a virtually unlimited number of genetic polymorphism without environment influence. This work's objective was to study the genetic variability of 17 sweet passion fruit accesses, using RAPD molecular markers. One access of P. quadrangularis and another of P. edulis were used as outgroups. Genomic DNA samples of each one of them were extracted and 11 decamers primers (OPD 04, 07, 08 e16; OPE 18 and 20; OPF 01 and 14; OPG 08; OPH 12 and 16) were used to obtain the markers. The markers have been converted into a matrix of binary data, used as base to estimate genetic distances between accesses and to perform grouping and graphic dispersion analysis. From the total amount of markers, considering only P. alata accesses, it was observed 87 (62.12%) polymorphic bands, showing great intraspecific variability. Grouping analysis based on genetic distances allowed to subdivide 17 P. alata accesses in, at least, five groups of genetic similarity. The wild accesses contributed the most to the genetic basis expansion of the studied materials, opening good prospects for their use in breeding programs.
