The chemical characterization of aqueous extracts (AE) of barks, leaves and branches and the saponin fraction denominated QB-90 obtained from Quillaja brasiliensis, a native species from Southern Brazil, show remarkable similarities to Quillaja saponaria saponins which are known as adjuvants in vaccine formulations. In vivo toxicity assays of AE and QB-90 showed not to be lethal for mice in dos...
In the last decades, significant efforts have been dedicated to the search for novel vaccine adjuvants. In this regard, saponins and its formulations as "immunostimulating complexes" (ISCOMs) have shown to be capable of stimulating potent humoral and cellular immune responses, enhanced cytokine production and activation of cytotoxic T cells. The immunological activity of ISCOMs formulated with ...
objective(s) the immunoadjuvant potential of cross-linked dextran microspheres (cdm) as absorption enhancer and quillaja saponins (qs) as immunomodulator adjuvant was evaluated. materials and methods cdm loaded or tetanus-mixed toxoid (tt) or quillaja saponin (qs) were nasally administered to rabbits in dry powder form, three times in 2 weeks interval and serum igg and nasal lavage siga titers ...
QS-21 is a saponin extracted from Quillaja saponaria, widely investigated as a vaccine immunoadjuvant. However, QS-21 use is mainly limited by its chemical instability, significant variety in molecular composition and low tolerance dose in mammals. Also, this compound tends to form micelles in a concentration-dependent manner. Here, we aimed to characterize its conformation and the process of m...
Chlorophytum borivilianum is commonly known as safed musli and is sold all over the world for its medicinal values. Tubers of this plant are used to cure reproductive disorders and studies indicate that saponins are the main compounds that are responsible for its therapeutic values. In the present investigation, saponin content and type of saponins in the tubers (without peels), peels of tubers...
