  At present, the effects of quercetin liposome on anxiolytic activity and cognitive function are unclearly known. In this study, male Wistar rats were administered quercetin liposome via intranasal route once daily continually for 4 weeks. The anxiolytic activity and cognitive enhancing effect were determined after single administration, 1, 2, 3 and 4 weeks of treatment using elevated plus maze test and Morris water maze test respectively. The results showed that quercetin liposome significantly increased both number of opened arm entry and time spent in the opened arm. In addition, the quercetin liposome also decreased escape latency and increased retention time markedly. Therefore, our results demonstrated the anxiolytic activity and cognitive enhancing effect of quercetin liposome and suggested that it might be used as a novel therapeutic strategy for anxiety disorder and cognitive deficit condition.

  An in vitro permeation of a hydroalcoholic extract of Phyllanthus amarus (PaE) was investigated using excised human epidermis and shed king cobra skin as the barrier membranes. Donor and receptor compartments of diffusion cells were pH–controlled to simulate the permeation environment of the human skin. The PaE was analyzed by using normal–phase densitometric TLC detected at λ 280 nm and toluene:ethyl acetate (17:3) as the mobile phase. There were four major components observed in the saturated solution of the donor at pH 5.5. Over 24 h, only one component, possibly phyllanthin, was found in the receptor solution after permeation across the human epidermis, while two components, possibly phyllanthin and an another unknown permeated, permeated through shed snake skin. When compared to the saturated donor concentration, phyllanthin gave permeation fluxes of 0.04±0.01 and 0.12±0.02 %·cm–2·h–1 through the human and shed snake skins, respectively. It seems that only certain component(s) of the P. amarus extract could permeate through the skins, and by comparison, at a slower rate across the human skin than shed snake skin.

  Scales of shed king cobra (Ophiophagus hannah) skin from the dorsal portions, (SSS) and human breast epidermis (HE) were used as barrier membranes for comparison in an in vitro drug permeation study of nine active compounds (MW range 150-300 g mol-1, pKa 3-10). Each compound, saturated in a donor solution at pH 4.0 or 5.6, permeated through the barrier membrane, fully hydrated. A receptor solution at pH 7.4 was sampled for quantification at its λmax by UV-Visible spectrophotometry and/or HPLC. The permeability coefficients of nine compounds were correlated to the n-octanol/water partition coefficients of these compounds. The permeability coefficient of these compounds using HE and SSS was correlated. Scales of shed skin from the dorsal portions of king cobras were shown to be well correlated to the human breast epidermis in this in vitro aqueous permeation study of these compounds.
