Production of biomolecules of interest to the anxiolytic herbal medicine industry in yellow passionfruit leaves (Passiflora edulis f. flavicarpa) promoted by mycorrhizal inoculation

Abstract

BACKGROUND Our contemporary way of life has led us to consume high amounts of chemically‐synthesized allopathic medicinal products and anxiolytics to which a viable alternative is the use of Passiflora‐based herbal medicines with composition containing vitexin, a flavonoid with anxiolytic and antidepressant properties. Arbuscular mycorrhizal fungi (AMF) are known for enhancing the production of biomolecules, however, increase production of phytochemistry in Passiflora edulis f. flavicarpa has not been reported in the literature. Our aim was to select AMF to benefit the production of vitexin in leaves of P. edulis by inoculating seedlings in the region of roots with Acaulospora longula, Claroideoglomus etunicatum and Gigaspora albida. RESULTS The inoculation increased the concentration of vitexin in 63.64% and the inoculation with A. longula also increased the content of flavonoids and total saponins in the leaves in relation to the control. CONCLUSION The increase in the production of vitexin in the leaf in response to the inoculation with AMF, with emphasis to A. longula, interests the pharmaceutical industry and can generate profit to the production of yellow passionfruit‐based anxiolytic herbal medicine. © 2019 Society of Chemical Industry

Use of mycorrhizal fungi releases the application of organic fertilizers to increase the production of leaf vitexin in yellow passion fruit

“…The fungus was multiplied in the soil, with millet as host, and kept at 4 °C until the time of application. This isolate was favored due to promoting enhanced growth and accumulation of secondary metabolites in yellow passion fruit plants in a recent study …”

“…The high‐performance liquid chromatograph was equipped with a photodiode array detector, a binary pump, a degasser, an automatic injector, a C 18 column (250 mm × 4.6 mm i.d., particle size 5 μm), and a C 18 pre‐column (4 mm × 3.9 μm). For analysis of the chromatographic data, the computational program Chromeleon version 6.0 (3000‐RS Dionex, Thermo Fisher Scientific®) was used …”

“…When applied to yellow passion fruit seedlings, AMF inoculum favors plant growth, reducing the time until transplanting to the field and increasing the tolerance to abiotic stresses . Moreover, they optimize the production of phenolic compounds, such as vitexin, a flavonoid of importance to the species and of interest to the pharmaceutical industry owing to its therapeutic properties as an anxiolytic and sedative …”

“…Furthermore, the highest colonization rate by AMF can also influence secondary metabolites biosynthesis (Zitter-Eglseer et al, 2015;Oliveira et al, 2019a) (Figure 1).…”

“…In relation to the benefits proportionated to plants, studies reported that AMF inoculation can increase the growth (Tarraf et al, 2015), offer enhanced nutritional uptake (Domokos et al, 2018), improve stress tolerances (He, Zhang, & Tang,2016;Chang et al, 2018) and regulate the production of primary and secondary compounds from plant metabolism (Parada et al, 2019;Paskovic et al, 2019). In this regard, studies were conducted with plants of medicinal interest, registering the increment of biomolecules production, which confer medicinal properties Oliveira et al, 2019a).…”
