1. Extraction and analysis of the parietal polysaccharides of acorn pericarps from Quercus trees
Abstract Acorns produced by Quercus trees are currently underexploited and undervalued. To evaluate the commercial and health benefits of acorns, we examined the cell wall components of acorn pericarps from Quercus suber and Quercus ilex, growing in North-Western Algeria. Acorn pericarps were sequentially extracted and the polysaccharide fractions were analy

2. Mangostanaxanthone VIIII, a new xanthone from Garcinia mangostana pericarps, α-amylase inhibitory activity, and molecular docking studies
ABSTRACT A new xanthone: mangostanaxanthone VIIII [1,3,5,6,7-pentahydroxy-2-(3-methylbut-2-enyl)-8-(3-hydroxy-3-methylbut-1-enyl) xanthone] (5) and four known xanthones: mangostanaxanthones I (1) and II (2), γ-mangostin (3), and mangostanaxanthone VII (4) were separated and characterized from the acetone fraction of Garcinia mangostana L., Clusiaceae (mango

3. Clusia criuva Cambess. (Clusiaceae): anatomical characterization, chemical prospecting and antioxidant activity
ABSTRACT This study aims the anatomical description and chemical characterization of aerial parts of Clusia criuva Cambess., Clusiaceae in addition to the evaluation of the antioxidant activity of crude extracts, correlated to the flavonoid content. The morphological characterization was performed using traditional techniques of plant anatomy. For phytochemi

4. Structure and histochemistry of medicinal species of Solanum
ABSTRACT Studies on native medicinal plants strengthen initiatives to preserve the environments where those species naturally occur, many of them already strongly menaced even before their potential to humankind is known. Root and stem barks, leaves, and pericarps samples of Solanum agrarium Sendtn., S. lycocarpum A. St.-Hil., S. palinacanthum Dunal, S. pani

5. Antioxidant activities of fractions from longan pericarps
The antioxidant activities of ethanolic crude extract (LPCE) and its four different solvent sub-fractions (namely, diethyl ether fraction (LPDF), ethyl acetate fraction (LPEF), n-butyl alcohol fraction (LPBF) and residue fraction (LPR)) from longan pericarps were investigated employing various systems including 2,2-diphenyl-1-picrylhydrazyl (DPPH)/ 2,2'-amin

6. Limonoides isolados dos frutos de Carapa guianensis Aublet (Meliaceae)
Six limonoids were isolated in hexane extract obtained from the seeds and pericarps of Carapa guianensis. The structures of the limonoids were determined based on the analysis of High Resolution Mass Spectroscopy and Nuclear Magnetic Resonance (uni-and bi-dimensional experiments) data. This is the first report of isolation of the limonoid 6α-acetoxy-7-deace

8. Análise química e biológica dos alcalóides de aspidosperma ramiflorum Muell. Arg. e de aspidosperma tomentosum Mart / Chemical and biological analisys of the alkaloids from aspidosperma ramiflorum Muell. Arg and aspidosperma tomentosum Mart
Even before the advent of writing, man already searched the nature for the cure of his illnesses. Among the different classes of natural products used for this purpose, monoterpenoid indole alkaloids exhibit large structural and pharmacological diversities and these compounds are commonly found in the Aspidosperma genus. In this context, the present work had

9. Pollination-, Development-, and Auxin-Specific Regulation of Gibberellin 3β-Hydroxylase Gene Expression in Pea Fruit and Seeds1
To understand further how pollination, seeds, auxin (4-chloroindole-3-acetic acid [4-Cl-IAA]), and gibberellins (GAs) regulate GA biosynthesis in pea (Pisum sativum) fruit, we studied expression of the gene PsGA3ox1 that codes for the enzyme that converts GA20 to biologically active GA1 using real-time reverse transcription-polymerase chain reaction analysis

10. Alleles of the maize P gene with distinct tissue specificities encode Myb-homologous proteins with C-terminal replacements.
The maize P gene is a transcriptional regulator of genes encoding enzymes for flavonoid biosynthesis in the pathway leading to the production of a red phlobaphene pigment. Multiple alleles of the P gene confer distinct patterns of pigmentation to specific floral organs, such as the kernel pericarp and cob tissues. To determine the basis of allele-specific pi

11. Tissue-specific and light-regulated expression of a pea nuclear gene encoding the small subunit of ribulose-1,5-bisphosphate carboxylase.
We have examined the expression of a member of the multigene family encoding the small subunit (rbcS) of ribulose-1,5-bisphosphate carboxylase in various tissues of pea. The rbcS gene, pPS-2.4, was characterized by DNA sequence analysis and 5' and 3' end mapping of its mRNA transcript. rbcS polypeptides were shown to be differentially present in various tiss

12. Hormone and Seed-Specific Regulation of Pea Fruit Growth1
Growth of young pea (Pisum sativum) fruit (pericarp) requires developing seeds or, in the absence of seeds, treatment with gibberellin (GA) or auxin (4-chloroindole-3-acetic acid). This study examined the role of seeds and hormones in the regulation of cell division and elongation in early pea fruit development. Profiling histone H2A and γ-tonoplast intrins
