Enhancement of Strawberry Shelf Life via a Multisystem Coating Based on Essential Oil Loaded in Polymeric Nanocapsules.

Strawberries () are susceptible to mechanical, physical, and physiological damage, which increases their incidence of rot during storage. Therefore, a method of protection is necessary in order to minimize quality losses. One way to achieve this is by applying polymer coatings.

Antiprotozoal Activity against of Flavonoids Isolated from Kunth.

Amebiasis caused by is nowadays a serious public health problem worldwide, especially in developing countries. Annually, up to 100,000 deaths occur across the world. Due to the resistance that pathogenic protozoa exhibit against commercial antiprotozoal drugs, a growing emphasis has been placed on plants used in traditional medicine to discover new antiparasitics.

HPLC Method Validation for Jatropha dioica Extracts Analysis.

Jatropha dioica is a popular plant used in Mexican herbal medicine to treat several diseases. Cytotoxicity, antimicrobial and antiviral activities have been reported for root extracts, while riolozatrione, 6-epi-riolozatrione, citlalitrione and jatrophatrione, among others, have been identified as the principal components. In this work, an HPLC/DAD method for the analysis of riolozatrione and other major compounds in extracts of different polarities was validated.

Simultaneous GC-FID Quantification of Main Components of L. and Essential Oils in Polymeric Nanocapsules for Antioxidant Application.

The essential oils (EO) of and have been widely used due to their antioxidant activity. However, due to their high volatility, the loading of EO into polymeric nanocapsules (NC) represents an efficient way of retaining their effect in future topical administration. In this way, the quantitative determination of EO incorporated into NC is necessary for simultaneous monitoring of the main components of the EO during the nanoencapsulation process as well as for precise and exact dosing of the components used during the performance of and biological tests.

Antimicrobial and antioxidant activities and chemical characterization of essential oils of Thymusvulgaris, Rosmarinus officinalis, and Origanum majorana from northeastern México.

There have been no reports of antifungal activity and composition of extracts from Thymus vulgaris, Rosmarinus officinalis or Origanum majorana from northeastern México. Antifungal activity of these oils against Trichophyton rubrum, Trichophyton tonsurans, Trichophyton mentagrophytes, Microsporum gypseum, Microsporum canis and Epidermophyton floccosum was measured by diffusion assay. Additionally, antibacterial and antioxidant activities were evaluated.

Chemical compositions and antimicrobial and antioxidant activities of the essential oils from Magnolia grandiflora, Chrysactinia mexicana, and Schinus molle found in northeast Mexico.

The essential oils from Magnolia grandiflora and Chrysactinia mexicana leaves, and from Schinus molle leaves and fruit, were characterized by gas chromatography/flame-ionization detection and gas chromatography/mass spectrometry. Twenty-eight compounds from M. grandiflora leaves were identified (representing 93.

Activity against Streptococcus pneumoniae of the essential oil and 5-(3-buten-1-ynyl)-2, 2'-bithienyl isolated from Chrysactinia mexicana roots.

The essential oil of Chrysactinia mexicana retrieved from the root bark was characterized by gas chromatography coupled to a mass detector. The compounds silphiperfol-5-ene, 7-epi- silphiperfol-5-ene, modheph-2-ene, alpha-isocomene, beta-isocomene and methyl-linoleate were identified. The principal compound (76.
