Background:  Leptadenia hastata is a leafy, climbing plant of whose root, leaf and bark is widely consumed in Northern Nigeria. Decoctions made from the leaf is locally used in treatment of diabetes as well as for numerous trado-medicinal processes. This study investigates the physico-chemical as well as phytochemical compounds present in the n-hexane extract of Leptadenia hastata. Method: Physical and chemical profile was determined using Smart Spectro test kits and a mass spectrometer to determine the presence of elements and physical properties. Results: Phytochemical analysis revealed the presence of steroids, triterpenoids and cardiac glycosides. The elemental analysis revealed that Na, SO4 and PO4 had the highest levels in the extract. Pb, Hg and Cd were not detected which showed that the plant extract was not toxic. Other elements (NO4, Mn, Fe, K, Ni, Si, Cn, Zn, Ca, Mg, NH4, Cr and F) were present in varying concentrations which may contribute to its nutritive composition. Conclusions: Various elements present in Leptadenia hastata may have either a direct or indirect role in the control and management of diabetes mellitus, since diabetes is associated with marked alterations in trace elements concentrations and may replace diminished element stores in the treatment of diabetes mellitus.

ESTUDIO PRELIMINAR DE LA VARIABILIDAD INTRAESPECÍFICA DE PROTEÍNAS SEMINALES EN Araujia hortorum FOURN (Apocynaceae). PRELIMINAR STUDY OF THE INTRASPECIFIC VARIABILITY OF SEED PROTEINS IN Araujia hortorum FOURN (Apocynaceae) Gonzales Medrano, M.F, Galvez, M.J , González, S.R y Villamil, C.B DOI: https://doi.org/10.33017/RevECIPeru2006.0016/ RESUMEN Araujia hortorum Fourn es una enredadera perenne sudamericana que se comporta como invasora en cultivos y en áreas de reserva natural. Han habido controversias sobre la conveniencia de considerarla como especie independiente o como entidad infraespecífica subordinada a A. sericifera Brot. (Araujia sericifera f. hortorum Malme). Como criterio complementario para definir esta situación se han comparado muestras de semillas provenientes de nueve poblaciones de la región pampeana argentina (A. cf. hortorum) y una coleccionada en la selva misionera (A. cf. sericifera). Mediante la utilización de los métodos de electroforesis en gel de poliacrilamida (PAGE-SDS) y de inmunotransferencia (IT, “immunoblotting”) se ha podido detectar la presencia de 19 y 18 bandas proteicas respectivamente, aunque no coincidentes entre sí. La utilización del Índice de Jaccard arrojó valores de similitud entre 0.39-1.00 y 0.53-1.00 respectivamente. Las diferencias encontradas deben atribuirse, en parte, a la dificultad para determinar la presencia o ausencia de algunas de las bandas de menor intensidad. La población misionera mostró menor similitud con las pampeanas que éstas entre sí. Los resultados obtenidos demuestran una considerable uniformidad genética entre ambas entidades putativas, lo que sugiere la necesidad de comparar poblaciones adicionales de ambas para evaluar más objetivamente la consistencia de estos métodos en su caracterización sistemática. Palabras clave: Inmunotransferencia, Araujia, proteínas seminales, Apocynaceae. ABSTRACT Araujia hortorum Fourn is a sudamerican perennial climbing plant that performs like an invasive in crops and natural reserve areas. There have been controversies about to consider it as independent specie or like an intraspecific entity dependent to A. sericifera Brot. (Araujia sericifera f. hortorum Malme). As a complement approach to define its situation, It has been compared some seeds samples coming from nine populations from Argentina‟s pampean region (A. cf. hortorum) and another from Misionera jungle (A. cf. sericifera). through use the method of polyacrylamide gel electrophoresis (PAGE-SDS) and immnunoblot assay (IT, “immunoblotting”), it have been able to detect the presence of 19 and 18 protein bands respectively, although they are not coincident to each other. The use of the Jaccard Index shows values of similarity among 0.39-1.00 and 0.53-1.00, respectively. Differences should be attributed, partly, to the difficulty to determine the presence or absence of some of the bands of small intensity. The population from Misionera jungle showed smaller similarity with the pampeans that between each other. The results realized a considerable genetic uniformity among both putative entities that suggests the necessity to compare both additional populations in order to evaluate the consistency of these methods more objectively in their systematic characterization. Keywords: Immunoblotting, Araujia, seeds proteins, Apocynaceae.

Hops, the cone of a climbing plant by the same name, are a key ingredient in beer. Brewers use hops to impart flavors and aroma in their malted concoctions, and they value the ingredient’s preservative properties. This chapter explains the global origins and botanical characteristics of the common hop, Humulus lupulus l., used in brewing. It then describes how brewing, and hop agriculture along with it, spread from Europe to temperate regions across the world. Hop growing reached North America along with the early English colonies and fared quite well. By 1800, New York and New England emerged as producers for the global economy.

A new monotypic genus of whiteflies (Aleyrodidae), Gadigaleyrodes gen.n., is described and illustrated for G. froggatti sp.n. from New South Wales, Australia. Specimens were collected by W. W. Froggatt in 1899 on Syncarpia glomulifera, and subsequently by P. S. Gillespie on an unknown climbing plant. The genus has unusual morphological features with traits common to both Aleurodicinae and Aleyrodinae. The subfamily placement is discussed, and a key provided to discriminate this taxon from similar whitefly genera in Australia.

Epipremnum pinnatum is a vegetative, type of vines and climbing plant that can be found in a semitropical and tropical country in South East Asia and Asian region. It has been used as folk remedies due to its medicinal properties and capability in enhancing the immune system. However, limited scientific data are present to support this claim. Thus, the present study was focused on the determination of phytochemical properties of the extract E. pinnatum and the effect on the pancreatic lipase inhibitory activities. Phytochemical of E. pinnatum was extracted using supercritical carbon dioxide (CO2) at 6000 psi and 40°C. The extracted oil was analyzed using Follin- Ciocalteu method to determine the phenolic components and followed by gas chromatography analysis. Chicken pancreas was used to investigate pancreatic lipase inhibitory activities of the extracted E.pinnatum. The results indicated that extract E.pinnatum could inhibit the chicken pancreatic lipase activity and based on the analysis obtained, the amount of lipase activity inhibited was 74 % by using 48 μg/ml of extract E.pinnatum.
