Preparation and characterization of microcapsules of Pterodon pubescens Benth. by using natural polymers
An oleaginous fraction obtained from an alcohol extract of the fruit of Pterodon pubescens Benth. (FHPp) was microencapsulated in polymeric systems. These systems were developed using a complex coacervation method and consisted of alginate/medium-molecular-weight chitosan (F1-MC), alginate/ chitosan with greater than 75% deacetylation (F2-MC), and alginate/low-molecular-weight chitosan (F3-MC)....
متن کاملPterodon pubescens Benth: Stability Study of Microencapsulated Extract and Isolated Compounds Monitored by Antinociceptive Assays
As sementes de Pterodon pubescens Benth. (Pp), disponíveis comercialmente no Brasil, são utilizadas na medicina popular em preparações anti-inflamatórias, analgésicas e anti-reumáticas. O presente estudo demonstrou as propriedades antinociceptivas da mistura de isômeros 6α-hidroxi-7βacetoxi-vouacapano-17β-oato de metila e 6α-acetoxi-7β-hidroxi-vouacapano-17β-oato de metila (C1) isolada de Pp, e...
متن کاملAntinociceptive effect of geranylgeraniol and 6α,7β-dihydroxyvouacapan-17β-oate methyl ester isolated from Pterodon pubescens Benth
BACKGROUND Pterodon pubescens Benth seeds are commercially available in the Brazilian medicinal plant street market. The crude alcoholic extracts of this plant are used in folk medicine as anti-inflammatory, analgesic, and anti-rheumatic preparations. The aim of this study was to evaluate the contribution of geranylgeraniol (C1) and 6alpha, 7beta-dihydroxyvouacapan-17beta-oate methyl ester (C2)...
متن کاملStructural Characterisation of a Polysaccharide from Radix Ranunculus ternati
A water soluble polysaccharide, HB-1, with a molecular weight of 23,930, was isolated from radix Ranunculi ternati. by hot water extraction, ethanol precipitation, deproteination，ultrafiltration and gel-filtration column chromatography. Its sugar composition was determined by GLC as Glc, Ara, and Gal in a molar ration of 16.071: 2.722: 1. And the absolute configuration of Glc was identified as ...
