Acute toxicity of Schizolobium parahyba aqueous extract in mice

Phytotherapy Research, 2009
AbstractThe herbal extract of Schizolobium parahyba leaves is used commonly in the Brazil central region to treat snakebites. This study evaluates the acute toxicological effects of Schizolobium parahyba aqueous extract in mice 24 h after intraperitoneal administration. Acute toxicity was evaluated using biochemical, hematological and histopathological

The mannan from Schizolobium parahybae endosperm is not a reserve polysaccharide

Carbohydrate Polymers, 2007
Abstract In higher plants, mannans are found as dominant reserve material in the endosperm of Arecaceae seeds and also in some species from Apiaceae, Rubiaceae and Asteraceae. A linear β(1 → 4)- d -mannan was now isolated from the endosperm of Schizolobium parahybae , family Caesalpiniaceae, a native of Southern Brazil. Its seeds were germinated and

Purification and pH stability characterization of a chymotrypsin inhibitor from Schizolobium parahyba seeds

Phytochemistry, 2004
Schizolobium parahyba chymotrypsin inhibitor (SPCI) was completely purified as a single polypeptide chain with two disulfide bonds, by TCA precipitation and ion exchange chromatography. This purification method is faster and more efficient than that previously reported: SPCI is stable from pH 2 to 12 at 25 degrees C, and is highly specific for ...

Topographical Analysis of Schizolobium Parahyba Chymotrypsin Inhibitor (Spci) by Atomic Force Microscopy

Protein & Peptide Letters, 2002
Atomic Force Microscopy (AFM) has been a useful tool for molecular surface analysis and to estimate topographical properties of proteins. Here we report a topographical study of a chymotrypsin inhibitor from Schizolobium parahyba seeds (SPCI) by AFM. The underlying structure of SPCI oligomers has been resolved in nanometer order resolution.

Protective Effect of Schizolobium parahyba Flavonoids Against Snake Venoms and Isolated Toxins

Current Topics in Medicinal Chemistry, 2011
Four compounds (isoquercitrin, myricetin-3-O-glucoside, catechin and gallocatechin) were isolated from lyophilized aqueous extract of Schizolobium parahyba leaves by chromatography on Sephadex LH-20, followed by semipreparative HPLC using a C-18 column, and identified by 1H and 13C NMR.

Isolation and characterization of microsatellite loci in Schizolobium parahyba (Leguminosae)

Molecular Ecology Notes, 2003
AbstractPrimer sequences for 16 microsatellite loci were developed from Schizolobium parahyba, a tropical tree species. Twelve loci were found to be polymorphic after screening diversity in individuals from Belize. A total of 39 alleles were found at nine loci.

Anti‐snake venom properties of Schizolobium parahyba (Caesalpinoideae) aqueous leaves extract

Phytotherapy Research, 2008
AbstractMany medicinal plants have been recommended for the treatment of snakebites. The aqueous extracts prepared from the leaves of Schizolobium parahyba (a plant found in Mata Atlantica in Southeastern Brazil) were assayed for their ability to inhibit some enzymatic and biological activities induced by Bothrops pauloensis and Crotalus durissus ...

Topical curcumin-loaded hydrogels obtained using galactomannan from Schizolobium parahybae and xanthan

Carbohydrate Polymers, 2015
The curcumin (CUR)-loaded binary hydrogel was formulated using xanthan and galactomannan from Schizolobium parahybae (guapuruvu). The binary hydrogels presented gel characteristics, stable pH values and mechanical stress resistance even after 45 days of heat exposure (45 °C). The CUR-loaded hydrogel content was 98.6% for XGMC (xanthan and galactomannan
