To facilitate effective resource utilization, we have investigated triterpene saponins such as saikosaponin from the aerial parts of Bupleurum (B.) falcatum L., which are commonly discarded. Seven oleanene saponins were isolated from this plant; they were classified as the 13,28-epoxy type, 12-ene type, 9(11),12-diene type, and 28-acid type on the basis of their structural characteristics. For ...
In the present work the effect of quercetin obtained from (Allium cepa). Albizzia lebbek (crude extract of seeds) and a pure saponin fraction of Albizzia has been studied on the mast cells in the mesentery and peritoneal fluid of rats subjected to anaphylaxis. The results show a mast cell membrane stabilizing effect of these test drugs.
Quillaia extracts (synonyms: quillaja extracts, bois de Panama, Panama bark extracts, quillai extracts, Quillay bark extracts, soapbark extracts; C.A.S. no. 68990-67-0, INS no. 999) are obtained by aqueous extraction of the milled inner bark or whole wood of Quillaja saponaria Molina (family Rosaceae), which is a large evergreen with shiny, leathery leaves and a thick bark, native to China and ...
Four new furostanol saponins 1-4, along with two known furostanol saponins 5 and 6 and one known spirostanol saponin 7 were isolated from the rhizomes and roots of Smilax scobinicaulis. The structures of the new saponins were elucidated as 26-O-β-D-glucopyranoside-3β,26-dihydroxy-(25R)-5α-furostan-22-methoxyl-6-one-3-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside (1), 26-O-β-D-glucopyranoside...
The potential effect of the fucose mannose ligand (FML)-vaccine on immunotherapy of canine visceral leishmaniasis was assayed on five mongrel dogs experimentally infected with Leishmania donovani and on 21 Leishmania chagasi naturally infected dogs when seropositive to FML but completely asymptomatic. The clinical signs of the experimentally infected, symptomatic dogs only disappeared after the...
Inactivated polio vaccines (IPV) have an important role at the final stages of poliomyelitis eradication programs, reducing the risks associated with the use of attenuated polio vaccine (OPV). An affordable option to enhance vaccine immunogenicity and reduce costs of IPV may be the use of an effective and renewable adjuvant. In the present study, the adjuvant activity of aqueous extract (AE) an...
Abstract Functional foods, drug delivery systems, and cosmetics are the main areas of application for multiphase where use naturally derived compounds is preferred. Hence, this study aimed to assess possibility using natural surfactants saponin-rich extracts produce emulsions containing antibacterial antioxidant cinnamon clove essential oils (EOs). The analyses nanoparticles dynamic light scatt...
