Mung bean seed coat (MBSC) is a healthcare product in Asian countries. The aim of this study was to investigate the effect of an MBSC ethanol extract on the bioavailability of cyclosporine A (CsA) in rats. Rats were orally dosed with CsA alone or in combination with MBSC ethanol extracts (500 mg/kg, p.o.). The blood levels of CsA were assayed by liquid chromatography with an electrospray ionization source and tandem mass spectrometry (LC-MS/MS). The everted rat intestinal sac technique was used to determine the influence of MBSC on the absorption of CsA. The results reveal that combined CsA intake with MBSC decreased the Cmax, AUC0-t, t1/2z and MRT0-t values of CsA by 24.96%, 47.28%, 34.73% and 23.58%, respectively (P<0.05), and significantly raised the CL/F by 51.97% (P<0.01). The in vitro results demonstrated that significantly less CsA was absorbed (P<0.05). The overall results indicate that after being concomitantly ingested, MBSC reduced the bioavailability of CsA, at least partially, in the absorption phase.

Cowpea Varieties

ABSTRACT Cowpea is an herbaceous legume susceptible to several insects and diseases; and the beetle Callosobruchus maculatus is the main pest causing direct losses in the production of this crop. The objective of this work was to assess the physical and bromatological characteristics of beans of cowpea varieties (Bico-de-Ouro, BRS-Novaera, BRS-Guariba and BRS-Tumucumaque) preferred by C. maculatus. Adults of C. maculatus were obtained from a storage unit of cowpea beans. The physical and bromatological characteristics and attractiveness of cowpea beans to insects were evaluated in laboratory. The preferences for oviposition with no choice and attraction to cowpea beans by C. maculatus are not related to the high protein content or physical characteristics of the bean seed coat (thickness and fiber content), since the insects were more attracted to beans of the variety Bico-de-Ouro, which had low crude protein content, the thickest seed coat and high NDF content.

Time Of Collection

Germination of Acacia auriculiformis A. Cunn. ex Benth. seeds was related to seed development. Full physiological development of seeds, indicated by maximum seed dry weight, was reached 82 days after anthesis; however, maximum percent germination was not reached before day 89. Later, germination declined gradually as dormancy and mortality increased. Most seeds were capable of germination without pretreatment at the time of collection, indicating that seed coats were not impermeable to water. Germination of seeds with moisture content from 14 to 29% can be achieved. Anatomical studies revealed that seeds reached maturity after compressing the parenchyma cells against the inside of the seed coat. The physical properties of the seed coat, therefore, did not control its permeability to water. After the developmental period, seed dormancy increased by further drying of seeds during storage.

Dna Strand Breakage

Hull/seed coat contains various plant cells that are responsible for sustaining the life of seeds in which phenolics perform significant roles in supporting their functions. In the present study, inhibitory activities against the oxidation of LDL and DNA of soluble- and insoluble-bound phenolics in the dehulled and hull fractions of lentils were determined. In addition, their α-glucosidase inhibitory activity was also assessed. The hulls possessed much higher levels of phenolics in both the soluble- and insoluble-bound forms than dehulled grain fractions, and this led to their potent activities in suppressing the oxidation of LDL and DNA and inhibiting α-glucosidase activity. The high bioactivities of hulls might be due to the existence of various types of cells such as palisade and parenchyma cells containing numerous phenolics for sustaining their functions. This study may help in a better understanding of the localization of soluble- and insoluble-bound phenolics in the structure of lentil.
