Evidence for Excitatory and Inhibitory Amino Acids Participation in the Neuropharmacological Activity of Alpha- and Beta-Amyrin Acetate
We evaluated the neuropharmacological profile of acetylated alphaand beta-amyrin (AcAMY) obtained by the acetylation of the isomeric mixture of alphaand beta-amyrin isolated from Protium heptaphyllum. Male Swiss mice were administered with AcAMY (2.5, 5, 10 and 25 mg/kg, i.p.), and anticonvulsant (pentylenetrazoleand pilocarpine-induced convulsions), sedative (barbiturate-induced sleep and open...
متن کاملAnti-oxidant and anti-inflammatory cyclic diarylheptanoids from Alnus japonica stem bark
A new cyclic diarylheptanoid namely alnuheptanoid B (3), along with four known cyclic diarylheptanoids: myricanone (1), (+)-S-myricanol (2), myricanone 5-O--D-glucopyranoside (4), and (+)-S-myricanol 5-O--D-glucopyranoside (5) were isolated from the EtOAc fraction of Alnus japonica Steud (family: Betulaceae) stem bark. Their structures were established by different spectroscopic analyses, as ...

متن کاملBioactive secondary metabolites from Salix tetrasperma Roxb.
Column chromatography of the light petroleum fraction from the methanolic extract of the stem bark of Salix tetrasperma Roxb. (Salicaceae) resulted in the isolation of beta-sitosterol acetate, friedelin, 3beta-friedelinol, beta-amyrin, beta-sitosterol, beta-sitosterol-O-glucoside in addition to palmitic acid. From the dichloromethane fraction of the leaves, catechol and tremulacin were isolated...
متن کاملAnti-inflammatory and chemopreventive effects of triterpene cinnamates and acetates from shea fat.
Four triterpene acetates, alpha-amyrin acetate (1a), beta-amyrin acetate (2a), lupeol acetate (3a), and butyrospermol acetate (4a), and four triterpene cinnamates, alpha-amyrin cinnamate (1c), beta-amyrin cinnamate (2c), lupeol cinnamate (3c), and butyrospermol cinnamate (4c), were isolated from the kernel fat (n-hexane extract) of the shea tree (Vitellaria paradoxa; Sapotaceae). Upon evaluatio...
