abstract = {The aqueous extracts of the seeds of oat (Avena sativa L.),
horse chestnut (Aesculus hippocastanum L.), soybean (Glycine
max L.), cowherb (Vaccaria hispanica [P. Mill.] Rauschert)
and quinoa (Chenopodium quinoa Willd.), and the roots of
soapwort (Saponaria officinalis L.) without any
preservatives were characterized in terms of theirsurface
tension, surface compression (dilational) rheology,
foamability and foam stability. The saponin content in the
extracts was determined using UPLC-MS and their interaction
with model lipid monolayers consisting of
dipalmitoylphosphatidylcholine (DPPC)/cholesterol and
Ceramide AP/stearic acid/cholesterol were analyzed by
surface pressure relaxation, surface compression elasticity
and neutron reflectometry (NR). The lipid composition was
chosen to mimic the cell membrane of keratinocytes – major
constituents of the human deeper skin layers, and the
intercellular lipids (“mortar”) in the “bricks and
mortar” model of the outermost layer of the epidermis
(stratum corneum). Bilayers of DPPC/cholesterol were
additionally characterized using dynamic light scattering
(DLS) and NR. The oat and soybean extracts were shown to be
much less abundant in saponins as compared to cowherb, horse
chestnut, soapwort or quinoa, and showed limited foaming
abilities. They did not affect significantly the model lipid
mono- and bilayers mimicking the skin outer layers, either.
The horse chestnut extract affected both model membranes to
the highest extent, yet without solubilizing the lipids.},
