Chemical, antioxidant, and antifungal analysis of oregano and thyme essential oils from Ecuador: Effect of thyme against and its application in banana rot.

The objective of this study was to evaluate the antioxidant capacity by spectrophotometric methods, the and antifungal effect against and the constitution of the essential oils (EO) of oregano and thyme in comparison with their commercial counterparts. The results showed by the EOs of extracted thyme (T-EO), commercial thyme (CT-EO), extracted oregano (O-EO) and commercial oregano (CO-EO), demonstrated antioxidant profiles with a radical neutralizing potential (DPPH•) of IC: 1.11 ± 0.

Changes in GC-MS metabolite profile, antioxidant capacity and anthocyanins content during fermentation of fine-flavor cacao beans from Ecuador.

The fermentation of fine-flavor cacao beans is a key process contributing to the enhancement of organoleptic attributes and monetary benefits for cacao farmers. This work aimed to describe the dynamics of the gas chromatography-mass spectrometry (GC-MS) metabolite profile as well as the antioxidant capacity and anthocyanin contents during fermentation of fine-flavor cacao beans. Samples of Nacional x Trinitario cacao beans were obtained after 0, 24, 48, 72, 96, and 120 hours of spontaneous fermentation.

Chemical Characterization of spp. Extracts with Antifungal Activity against Cocoa Pathogens.

Ecuador is one of the major cocoa producers worldwide, but its productivity has lately been affected by diseases. Endophytic biocontrol agents have been used to minimize pathogenic effects; however, compounds produced by endophytes are minimally understood. This work presents the chemical characterization of the species extracts that proved inhibition against cocoa pathogens.

ITS1 Barcode and Phytochemical Analysis by Gas Chromatography-Mass Spectrometry of Hook. f (Balanophoraceae) from Ecuador and Peru.

The use of medicinal plants is the basis of traditional healthcare. Recently, the use of herbal medicine has been increasing among consumers due to availability, economy, and less side effect. For instance, the hemiparasite plant has medicinal properties and could be found in some regions of America, from Costa Rica to Bolivia.

Anti-inflammatory potential of processing (Kunth) H. Rob. leaves aqueous extract.

Folk medicine uses decoctions of (Kunth) H. Rob. leaves for healing wounds, and moderate pains.

Effect of Cocoa Bean Shell Addition on Metabolite Profile and Antioxidant Activity of Herbal Infusions.

Cocoa bean shell (CBS) is a by-product with aromatic characteristics that can enhance the aroma and bioactivity of herbal infusions. This study was aimed to determine the effect of the addition of cocoa bean shell on the metabolite profile and antioxidant activity of infusions made with and and their mixtures. Metabolite profile was analyzed by gas chromatography-mass spectrometry combined with multivariate analysis.

Effect of solvent-solvent partition on antioxidant activity and GC-MS profile of Loes. leaves extract and fractions.

The use of guayusa ( Loes.) leaves as functional food has increase recently. This work discusses the antioxidant activity and volatile compounds of guayusa leaves extract and fractions.

Effect of resin content and pressing temperature on banana pseudo-stem particle boards properties using full factorial design.

The volume of global gross banana exports reached a record of 117.9 million tonnes in 2015 (FAO 2017), which agro-industrial wastes derived as the pseudo-stem, rachis and leaves do not have an industrial application instead they are discarded. This research study applies full factorial design and response surface methodology to determine the effect of pressing temperature and resin content on density (D), moisture (M), water absorption (WA), water swelling (WS), module of rupture (MOR), module of elasticity (MOE) and formaldehyde content (FC) of particle board made of banana pseudo-stem.

Identification of lupeol produced by (Kunth) H. Rob. leaf callus culture.

The lupeol detection in callus of (Kunth) H. Rob. leaves is discussed.

Antioxidant activity optimization and GC-MS profile of aqueous extracts of (Kunth) H. Rob. leaves.

The temperature and extraction time of aqueous extracts of (Kunth) H. Rob. (AEVP) leaves obtained by decoction were optimized for maximum recovery of DPPH radical scavenging activity, ABTS inhibition activity, total phenolic content (TPC) and total flavonoids content (TFC) using response surface methodology (RSM).
