An infusion prepared from the aerial parts of Salvia amarissima Ortega inhibited enzyme protein tyrosine phosphatase 1B (PTP-1B) (IC50~88 and 33 μg/mL, respectively). Phytochemical analysis yielded amarisolide (1), 5,6,4′-trihydroxy-7,3′-dimethoxyflavone (2), 6-hydroxyluteolin (3), rutin (4), rosmarinic acid (5), isoquercitrin (6), pedalitin (7) a new neo-clerodane type diterpenoid glucoside, named G (8a,b). Compound 8a,b is natural product, 2–6 are reported for first time species. All...
Se estudió la riqueza de especies plantas vasculares del municipio Guadalcázar en región Altiplano Potosino, un área clavada enla provincia fisiográfica conocida como Meseta Central y donde una parte significativa su superficie ha sido decretada natural protegida. registraron 813 5 tipos vegetación: matorral submontano, xerófilo, bosque Quercus, Pinus pastizal, siendo el submontano que alberga mayor florística, predominantemente familia Asteraceae. Un análisis patrón distribución todas las...
Fractionation of an aqueous extract from the aerial parts Ageratina grandifolia yielded a new natural product, namely, 4-hydroxy-3-((S)-1′-angeloyloxy-(R)-2′,3′-epoxy-3′-methyl)butylacetophenone (1), along with eight known compounds, including three flavonoids (2–4) and five chromenes (5–9). NMR data interpretation DFT-calculated chemical shifts combined DP4+ statistical J-DP4 probability analyses allowed for complete characterization compound 1. The presence 1 in plant that biosynthesizes...
Carica cnidoscoloides from Oaxaca is described and illustrated its affinities discussed. It differs all the other species of by needle-like urticating trichomes, entire subcapitate stigma, winged fruits. A new section, sect. Holostigma, to accommodate
General information about the genus Bauhinia in Yucatán Peninsula Biotic Province is presented. Five native species, B. divaricata L, erythrocalyx Wunderlin, jenningsii P. Wilson, herrerae (Britton et Rose) Standl. Steyerm., ungulata L. and 2 exotic monandra Kurz variegata L., are recognized. Species identification key, morphological descriptions, distribution maps, photographs Additional of common names uses region included.
A taxonomic review of Coulteria (Leguminosae) species present in the flora Tehuacan-Cuicatlan Valley was carried out as part treatment subfamily Caesalpinioideae this area. rosalindamedinae is described and illustrated a new species, it endemic from study area, morphologically related to C. pumila. comparative table, photographs pumila, are presented well key for their identification.
Two new species of Bauhinia L. (Fabaceae, Caesalpinioideae, Cercideae) are described and illustrated: B. miriamae R. Torres endemic to Oaxaca, wunderlinii from México, Belize, Honduras. Similarities differences divaricata discussed for both species; all three belong section Bauhinia. With these novelties, sect. comprises approximately 20 is most diverse in Mexico, where there 19 native 14 species.
Infusions and poultices prepared from the aerial parts of Baccharis heterophylla Kunth (Asteraceae) are widely used in Oaxaca (Mexico) for relieving painful inflammatory complaints. Therefore, antinociceptive potential an aqueous extract (31.6–316 mg/kg, p.o.) essential oil (30–177 µg/paw, i.pl.) plant was assessed using formalin test. Both preparations inhibited formalin-induced nociception response (100–316 mg/kg 100–177 respectively) during test’s second phase. Chemical analysis revealed...
As part of our effort to discover new α-glucosidase inhibitors from natural sources, it was found that an aqueous extract Melampodium perfoliatum (Cavanilles) Kunth (Asteraceae) inhibited the activity rat-intestinal α-glucosidases in a concentration dependent manner (IC 50 = 958 μg/mL). Fractionation active led isolation perfoliatin A (1), which against mammal and recombinant with maltase-glucoamylase obtained Ruminococcus obeum. Kinetic analysis revealed interaction 1 R. obeum-α-glucosidase...
A population of Lytta corallifera Haag-Rutenberg, 1880 (Coleoptera: Meloidae), one the less-studiedand rarest species its genus, was discovered near Charco Blanco, in Guadalcázar Biological Preservation Areain San Luis Potosí, Mexico. The rarity L. and apparent sensitivity to changes habitat make theabove region an important location for survival species.
Abstract A decoction prepared from the aerial parts of Melampodium divaricatum showed antinociceptive and antihyperalgesic responses when tested in formalin model mice. From CH 2 Cl fraction decoction, two non‐previously reported secondary metabolites, 3‐ O ‐ β ‐D‐glucopyranosyl‐16α‐hydroxy‐ ent ‐kaurane ( 1 ) melampodiamide [(2′ R *,4′ Z )‐2′‐hydroxy‐ N ‐[(2 S* ,3 ,4 R* )‐1,3,4‐trihydroxyoctadec‐2‐yl]tetracos‐4‐enamide] were separated characterized by spectroscopic, spectrometric,...
Pachyphytum (Crassulaceae) is a genus of perennial plants with ca. 20 species endemic to central Mexico. rogeliocardenasii described here as new species. It compared P. garciae, which morphologically similar. The the northwestern region state Querétaro where it was found on limestone walls. assigned category endangered (EN).
A new species of Tragia from the state Oaxaca, Mexico is described and illustrated; it different other known Mexican species, although somewhat similar in habit to T. nepetifolia. chiltepeca an erect herb with deeply cordate leaves acuminate apex a long petiole, pedunculate inflorescence, single pistillate flower proximal node, several male flowers at distal nodes, pyriform buds. This endemic Tuxtepec district. taxonomic key provided distinguish this Oaxaca.
Cuatro especies de Cucurbitaceae (Tecunumania quetzalteca Standley & Steyemark, Cionosicyos macanthus (Pittier) C. Jeffrey, Peponopsis adhaerens Naudin y Chalema synanthera Dieterle) se registran por primera vez para la flora del estado Oaxaca (la última además Guerrero) describe una nueva especie Parasicyos Dieterle.
