“…Calculation of the polarity of the measurement of the dipole moment, considering the dipole moment vector of each bond is present in the form of the resultant moment vector [22]. He et al emphasized that the plant's active compound were isolated with ethanol efficiently [23]. Piperine can dissolves in blood and reaches every tissue of the body because of having a high dipole moment.…”

Piperine, the most important compound of black pepper, is used for treating several diseases such as breast, colon, rectal, and stomach cancer. In this study, the thermodynamical properties of this molecule in blood were obtained by using DFT and HF at the level of B3LYP/6-31+g(d,p). The results of calculations are supported with the experimental literatüre knowledges. DFT and HF basis set calculations support to the each other as comparing theoretical calculations of the interactions taking place within the molecular species Keywords: Piperine, DFT and HF Abbreviations DFTdensity functional theory HF hartree-fock HOMO highest occupied molecular orbital LUMO lowest unoccupied molecular orbital FDA the food and drug administration CYP3A4 Cytochrome P450 3A4

“…Detailed analysis of the 2D NMR spectra and the correlations listed in Table 1 allowed to elucidate the structure of compound 1 as 3-(2-hydroxy-4-methoxybenzyl)chromane-4,7-diol. In related homoisoflavonoids (sappanins), the benzyl ring usually is monosubstituted (in the para position at C-4′) or disubstituted (2 substituents in ortho-position at C-3′ and C-4′), associated with chemical shifts between δ C 140 and 150 Zhao et al 2014;He et al 2016;Abegaz and Knife 2019), but in compound 1, these shifts were not observed. A meta-substitution (at C-4′ and C-6′) is unusual.…”

Homoisoflavonoids constitute a rare subclass of flavonoids restricted to only some plant species, including members of the genus Caesalpinia. This research focused on homoisoflavonoids from Caesalpinia bahamensis Lam., Fabaceae, a medicinal plant used in Cuban traditional medicine and known as "brasilete." An hydroalcoholic extract was prepared from the stem, followed by liquid-liquid partition and further chromatographic separations, resulting in the isolation and structure elucidation by nuclear magnetic resonance spectroscopy and mass spectrometry of an undescribed 3-(2-hydroxy-4-methoxybenzyl)chromane-4,7-diol, for which the name metasappanin was proposed.

“…En particular, la tara (Caesalpinia spinosa), un arbusto de tipo leguminosa originario del Perú que predomina en zonas secas y valles interandinos de Suramérica (He et al, 2016), se aprovecha en la industria química (taninos), alimenticia (aditivo hidrocoloide) y farmacéutica (ácido gálico, antioxidante) (Melo et al, 2013). Los taninos de C. spinosa son usados en medicina tradicional por sus propiedades antiinflamatorios, antimicóticos, antibacterianos, antisépticos, antitumorales y antioxidantes (Murga et al, 2016); su contenido de taninos está en un rango de 0,2 a 25% del total de masa seca, dependiendo de la especie vegetal, tiempo de cosecha, hábitat y método de extracción (Cuong et al, 2020).…”

Contextualización: Fusarium graminearum es un microorganismo de campo que afecta a gramíneas y causa grandes pérdidas, particularmente a cultivos de arroz. Para contrarrestar estos problemas fitosanitarios se aplican cantidades excesivas de plaguicidas, lo que causa daños a la salud y el ambiente. Una alternativa son los extractos vegetales con alto contenido de compuestos bioactivos. Vacío de conocimiento: los taninos tipo pirogalol contenidos en las vainas de Caesalpinia spinosa poseen propiedades biológicas, la inhibición del crecimiento micelial de Fusarium graminearum es efectiva en concentraciones bajas de UFC/ml. Propósito del estudio: el objetivo de esta investigación fue determinar in vitro la actividad antifúngica de los compuestos fenólicos de la tara (Caesalpinia spinosa) frente a Fusarium graminearum. Metodología: en primer lugar, se extrajeron los compuestos fenólicos por maceración y calentamiento (60 °C) mediante agua y una mezcla agua-etanol. Se determinó el contenido de compuestos fenólicos en los extractos mediante el método de Folin-Ciocalteu. En segundo lugar, se aisló una cepa de Fusarium obtenida de un cultivo de arroz y se identificó por claves taxonómicas; después, se realizaron suspensiones celulares con concentraciones 10⁷ y 10⁶ UFC/ml. Para la evaluación in vitro, un disco con inóculo de cada suspensión se colocó en medio cultivo agar papa dextrosa que contenía extracto de Caesalpinia spinosa. Resultados y conclusiones: el extracto acuoso por calentamiento con un contenido de 5,88 g ácido gálico/100 g muestra seca inhibió 30 y 70% de crecimiento micelial de Fusarium graminearum a una concentración de 10⁷ y 10⁶ UFC/ml respectivamente. Compuestos fenólicos de Caesalpinia spinosa presentaron propiedades de interés para el control de Fusarium graminearum y pueden ser ensayados in vivo e invernadero.
