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

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.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.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.
