Saponins are natural compounds able to form abundant foam, a desirable quality required in some chemical, foods, cosmetic and pharmaceutical processes. Ilex paraguariensis A. St. Hil. (Aquifoliaceae) known as mate, is a South American widely cultivated specie due to the preparation of a tea-like beverage from its leaves. Moreover, its green fruits are a rich source of non-toxic and very low haemolytic saponins. In this study, mate saponin fraction (MSF) was evaluated as a foam former, focusing on its foamability, foam lifetime, and film drainage in the presence of different electrolytes (ionic strength I = 0.024 M). Sodium dodecyl sulphate (SDS) and polysorbate 80 (Poly-80) were used as reference surfactants. The critical micelle concentration (CMC), the minimum attainable surface tension (γCMC), surface excess concentration (Γ) and cross-section molecular surface (A) values of MSF were comparable to those of Poly-80. The foamability of MSF and both reference surfactants was equivalent. The addition of MgCl2 resulted in a negative effect on MSF foamability. The salts NaCl, KBr, and KNO3 exhibited a negative influence on MSF foam lifetime. Similar behavior was observed for MSF film drainage (order of activity: Na2HPO4 > MgCl2 ≈ NaCl ≈ KNO3 > KBr), where a primary fast film drainage rate was followed by film thinning stabilization after around 5 min. The behavior described above seems to be uncorrelated to the solutions' zeta potential.

Aim: This study investigated the synergistic effect of docetaxel plus saponin fraction of Vitex doniana on prostate specific antigen and p53 in nitrsobis (2-oxopropyl) amine-induced prostate toxicity in Wistar rat. Methodology: Twenty-four (24) male Wistar rats with elevated serum prostate specific antigen level were selected from a group of sixty (60) rats pretreated with subcutaneous Nitrosobis (2-oxopropyl) amine 5 mg/kg daily for 4 weeks. The selected 24 male Wistar rats were then grouped into 6 groups of four (4) rats each. Group 1 was given 1ml normal saline daily from day 1-28. Groups 2, 3, 4, 5, and 6 further received subcutaneous nitrosobis (2-oxopropyl) amine 5 mg/kg daily from day 1-28. In addition, groups 3, 4, 5, and 6 were given weekly intravenous docetaxel 8 mg/kg on day 15 and 22. In addition to docetaxel, groups 4, 5, and 6 were further treated with oral saponin at 250 mg/kg, 500 mg/kg, and 750 mg/kg, respectively, daily, from day 15-28. Immunoenzymometric assay method was used for analysis of blood sample for prostate specific antigen. The prostate tissues were subjected to immuno study using the ImmunoCruz Staining System (Lab Vision Corporation, Fremont, CA, USA). The quantitative evaluation of p53 was done by calculating the percentages of p53-immunostained nuclei (labeling index). Results: Significant increase in prostate specific antigen and p53 expression were observed in group 2 (treated with Nitrsobis (2-oxopropyl) amine alone) when compared with group 1 (control). Dose dependent decrease in prostate specific antigen and p53 expression were observed in groups 4, 5, and 6, treated with docetaxel 8 mg/kg plus 250 mg/kg, 500 mg/kg, and 750 mg/kg of saponin respectively. Conclusion: Docetaxel plus Saponin fraction of Vitex doniana significantly reduced the serum prostate specific antigen concentration and p53 expression in a dose dependent manner, with the group treated with 750 mg/kg showing the highest decrease in the parameters tested.
