As a case study, a reliable HPLC method for simultaneous quantification of paeoniflorin from Paeoniae Radix and decursin from Angelicae Gigantis Radix in various commercial herbal medicine was developed based on analytical quality by design (AQbD) strategy. As a first step, risk assessment was performed to select the critical method parameters (CMPs) which were decided as organic mobile phase ratio and column oven temperature. In order to evaluate the effect of the CMPs on critical method attributes (CMAs) of peak resolution and tailing, central composite design (CCD) was employed. The final chromatographic conditions were optimized as follows: columnC18, 4.6 × 250 mm, 5 μm particle size; mobile phaseA: acetonitrile, B: 0.1% acetic acid water; detection wavelength235 nm for paeoniflorin, 325 nm for decursin; column oven temperature25C; flow rate1.0 mL/min; gradient mobile phase system as Time (min) : % A, 0:14, 25:14, 30:50, 60:50, 61:100, 65:100, 66:14, 75:14.

We investigated that the polysaccharide extract of an edible basidiomycetous white jelly mushroom, Tremella fuciformis, (TF-Glucan) exhibited statistically photoprotective activity by inhibiting matrix metalloproteases (MMPs) and increasing collagen synthesis, and an antiinflammatory activity by inhibiting nitric oxide and pro-inflammatory cytokines at the concentrations of less than 1000 μg/ml, which is not cytotoxic (p < 0.05). Additionally, TF-Glucan increased the expression of involucrin and filaggrin to prevent the disruption of UVB-induced barrier function (p < 0.05). TF-Glucan was assessed as a safe material by the human primary skin irritation (1, 3, 5%), human repeated insult patch test (no sensitization at 5%), 3T3 NRU phototoxicity assay (no phototoxicity, PIF < 2, MPE < 0.1), eye irritation test test by BCOP (no category, IVIS  3) and local lymph node assay (negative at 10, 25, 50%) for identifying potential skin sensitizing.
