Extraction, Characterization, and Nutraceutical Potential of Orchid for Insulin Resistance and Oxidative Stress in Wistar Rats.

is an endemic orchid of Mexico with cultural significance for its ornamental, food, religious, and medicinal uses. In traditional medicine, diabetic patients use the leaves of this plant to lower glucose levels. The present study evaluated the effect of leaves extract on the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT) in a model of obese rats with insulin resistance for its nutraceutical potential to reduce insulin resistance and oxidative stress.

Medicinal Orchids of Mexico: A Review.

Some species of the Orchidaceae family are used in Mexican traditional medicine. However, there are no current and critical compilations of the medicinal uses and pharmacological effects of the members of the Orchidaceae family. This review provides a current, critical, and comprehensive analysis of the traditional medicinal uses, pharmacological reports, and active compounds isolated from Mexican orchids.

Variation in the Floral Morphology of (Orchidaceae), a Mexican Endemic Orchid at Risk.

is an orchid endemic to Mexico, threatened by the destruction of its habitat and the extraction of specimens to meet its demand for ornamental and religious use. Most of its populations, including the most locally abundant ones, are found in Oaxaca state. Variations in some floral traits have been observed in these populations.

Composition of essential oil from the bark and leaves of two morphotypes of (Asteraceae), a medicinal plant in Oaxaca, Mexico.

The chemical composition of the essential oils (EOs) from leaves and bark of two morphotypes, white (WM) and black (BM) of obtained by microwave-assisted extraction (MAE) were analyzed by GC-MS. The major components of the bark EOs were aliphatic hydrocarbons (38.0% in WM, 48.

Microwave-Assisted Hydrodistillation of Essential Oil from : Evaluation of Its Antifungal Effect and Chemical Composition.

wilt, a vascular syndrome in a wide range of plants, is caused by the pathogen . The objective of this investigation was to evaluate the antifungal effect of four essential oils (EOs) (, , , and ), which were obtained by using microwave-assisted hydrodistillation (MAH), against . The yield obtained from with the use of MAH was 0.

Effect of Microwave and Ultrasound during the Killing Stage of the Curing Process of Vanilla (, Andrews) Pods.

The curing process (CP) of pods, which is a long and tedious process, is necessary to obtain the natural vanilla extract. This research evaluated the application of microwave (M) and ultrasound (U) during the "killing" stage of the CP and its effect on vanillin content and β-glucosidase activity. The pods were immersed in a container with water or with moistened samples for the M treatments.

Validation of the traditional medicinal use of a Mexican endemic orchid () through UPLC-ESI-qTOF-MS/MS characterization of its bioactive compounds.

Ethnopharmacological Relevance: The orchid is a medicinal orchid in Oaxaca, Mexico, used to treat diabetes, cough, wounds, and burns, prevent miscarriage and assist in labor. Each part of the plant (leaves, pseudobulbs, or flowers) is used by healers for certain treatment conditions, indicating that each part has different biocompounds with specific pharmacological activity.

Aim Of The Study: To characterize the biocompounds in extracts from leaves, pseudobulbs, and flowers of and evaluate their ROS inhibition capacity to associate it with medicinal uses.

Role of LTB4 and nitric oxide in the gastroprotective effect of leaves extract in the indomethacin-induced gastric injury in the rat.

Gastric injury is mainly described by inflammation of the gastric epithelium. Recently, our group of work demonstrated that leaves extract induces both an antioxidative action and an gastroprotective effect in a rat. However, the molecules involved in the gastroprotective action by are not known.

Bioactive compounds from Prosthechea karwinskii decrease obesity, insulin resistance, pro-inflammatory status, and cardiovascular risk in Wistar rats with metabolic syndrome.

Ethnopharmacological Relevance: The orchid Prosthechea karwinskii is a species endemic to Mexico, which is used in traditional medicine to lower glucose levels in patients with diabetes, and to treat inflammation-related problems. Recent studies have shown that this orchids can reduce glucose, cholesterol, and triglyceride levels in Wistar rats, which were previously induced to have metabolic syndrome (MS).

Aim Of The Study: To evaluate the effect of P.

Argemone mexicana (Papaverales: Papavaraceae) as an Alternative for Mosquito Control: First Report of Larvicidal Activity of Flower Extract.

Culex quinquefasciatus Say (Diptera: Culicidae), an arboviral and filarial vector, is one of the most widespread mosquitoes in the world. The indiscriminate use of synthetic chemical insecticides has led to the development of resistance in mosquito populations worldwide. The effect of continuous exposure to crude extracts of Argemone mexicana, the Mexican poppy, on the development and growth stages of second-instar larvae of the mosquito was studied, along with qualitative chemical analysis of the different plant parts.

Larvicidal effect of Clinopodium macrostemum essential oil extracted by microwave-assisted hydrodistillation against Culex quinquefasciatus (Diptera: Culicidae).

Introduction: In the present study, we determined the chemical composition of Clinopodium macrostemum essential oil obtained by microwave-assisted hydrodistillation and its effect on the growth and development of Culex quinquefasciatus mosquito larvae.

Methods: The essential oil compounds were identified by gas chromatography-mass spectrometry analysis, and bioassays were conducted to evaluate the influence on the developmental stages of early second instar larvae of Cx. quinquefasciatus until the emergence of adults, using essential oil concentrations of 50, 100, 200, 400, and 800mg/L.

Inhibition of the growth and development of mosquito larvae of Culex quinquefasciatus (Diptera: Culicidae) treated with extract from leaves of Pseudocalymma alliaceum (Bignonaceae).

Objective: To determine larvicidal activity of the essential oil, hydrolat and botanical extracts derived from leaves of Pseudocalymma alliaceum on mosquito larvae of Culex quinquefasciatus.

Methods: Groups of twenty larvae were used in the larvicidal assays. The mortality, relative growth rate, the larval and pupal duration and viability was estimated.
