Efficacy of Flos Sophorae as UV protective dye was examined in comparison to standard dyes of quercetin and rutin. Cotton was dyed using Flos Sophorae extract, quercetin, and rutin with 2 different concentrations for each dye. Each type of dyeing applied a temperature of 70℃ or 90℃ and a time of 30 min or 60 min. Color values of dyed samples were examined using a spectrocolorimeter. HPLC-DAD analysis indicated the amount of quercetin and rutin contained in Flos Sophorae used in the study. UPF values of dyed samples were measured using an ultraviolet transmittance analyzer. Experimental results indicated that dyeing cotton with Flos Sophorae extract, quercetin, or rutin increased the UPF value and decreased the UVA and UVB transmittance (%) regardless of dyeing conditions. A higher rank of UPF values were shown in cotton dyed using the Flos Sophorae extract that implied the possible concerted effect of quercetin, rutin, and flavonoid compounds contained in Flos Sophorae. The results indicated that Flos Sophorae is an effective natural dye that can improve the UV protective function of summer cotton fabric.

Both nitric oxide (NO) and interleukin-6 (IL-6) have been thought to have a role in the pathogenesis of inflammatory periodontal disease as it does in other inflammatory diseases, and the inhibitors of NO and IL-6 production have been considered as potential anti-inflammatory agents. In this study, we evaluated methanol extract of Sophorae Flos for inhibition of NO and IL-6 production in Prevotella intermedia LPS-induced mouse macrophages RAW264.7 cells. Dried Sopharae Flos was sliced, and extracted with 100% methanol. LPS from p. intermedia ATCC 25611 was prepared by the standard hot phenol-water method. NO production was assayed by measuring the accumulation of nitrite in culture supematants and IL-6 was measured using mouse IL-6 ELISA kit. Western blot analysis of iNOS and analysis of reverse transcription (RT)-PCR products were carried out. The methanol extract of Sophorae Flos concentration-dependently reduced the production of NO and the expression of iNOS protein and mRNA in RAw264.7 cells treated with P. intermedia LPS. Sophorae Flos also suppressed IL-6 production and the expression of IL-6 mRNA in RAw264.7 cells stimulated by P. intermedia LPS. The inhibition of NO and IL-6 production by Sophorae Flos may be useful in the therapy of inflammatory diseases such as periodontitis. This hypothesis, however, remains to be tested.

Objectives: The object of this study was to observe the in vitro antibacterial effects of five single(Pulsatillae Radix, Patrinae Radix, Sanguisorbae Radix, Sophorae Flos, and Sophorae Radix) aqueous herbal extracts, traditionally used for treating various gynecological diseases including mastitis in Korea, against Staphylococcus aureus. Methods: Antibacterial activities against Staphylococcus aureus of aqueous extracts of Pulsatillae Radix, PatrinaeRadix, Sanguisorbae Radix, Sophorae Flos, and Sophorae Radix were detected using standard agar microdilution methods. In addition, the effects on the bacterial growth curve were also monitored at Minimal Incubation Concentration(MIC) and $MIC{\times}2$ levels. The effects on the intracellular killing and bacterial invasion of individual test materials were also observed using murine macrophage(Raw 264.7) and human mammary gland carcinoma cell(MCF-7). Results: MIC of aqueous extracts of Pulsatillae Radix, Patrinae Radix, Sanguisorbae Radix, Sophorae Flos, and Sophorae Radix against Staphylococcus aureus were detected as $0.215{\pm}0.107$ mg/ml, $0.273{\pm}0.107$ mg/ml, $0.469{\pm}0.297$ mg/ml, $11.850{\pm}8.406$ mg/ml, and $0.664{\pm}0.546$ mg/ml, respectively. MIC of Ciprofloxacin was detected as $0.469{\pm}0.297{\mu}g/ml$ at same conditions. In addition, all five single aqueous herbal extracts were also showed marked dosage-dependent inhibition of bacterial growth. The effects of intracellular killing with Raw 264.7 and inhibition of bacterial invasion with MCF-7 cells were detected, in the order of Sophorae Flos, Pulsatillae Radix, Patrinae Radix, Sanguisorbae Radix and Sophorae Radix aqueous extracts in the present study. Conclusions: The results obtained in this study suggest that all five single aqueous herbal extracts showed antibacterial effects against Staphylococcus aureus and they also showed dosage-dependent inhibitory effects on the bacterial growth. They showed the significant intracellular killing and inhibition of bacterial invasion effects. It means, all five single aqueous herbal extracts may show potent anti-infectious effects against Staphylococcus aureus for mastitis.

Sophorae Flos (SF), a composite of flowers and flower-buds of Sophora japonica, has long been used in traditional Korean and Chinese medicines for the treatment of hemostasis and inflammation. In this study, we investigated anti-inflammatory effect of four EtOH extracts at the difference in blooming stages of flowers on LPS-induced inflammation in RAW264.7 cells. We classified the flowers of Sophora japonica with SF-1 (length of flower is shorter than calyx), SF-2 (length of calyx is shorter than flower), SF-3 (full bloom), and SF-4 (not blooming at all). We examined HPLC analysis, whether quercetin and rutin are major component of these Sophorae Flos extracts or not. As a result, SF-1 contained quercetin, but the others did not. In addition, quercetin, SF-1, and SF-4 act on the suppression of pro-inflammatory mediators including inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2, nitric oxide (NO), prostaglandin E2 ($PGE_2$) against lipopolysaccharide (LPS)-induced activation in RAW264.7 cells. Of these, SF-1 showed the best anti-inflammatory effect. These results suggest that Sophorae Flos with the highest content of quercetin would be used for the treatment of various inflammation diseases.

본 연구에서는 Box-Behnken 설계모델(BBD-RSM)을 사용하여 회화나무꽃 추출물을 첨가한 cosmeceuticals 유화액의 안정성 조건을 최적화하였다. BBD-RSM의 독립변수로는 유화제의 첨가량, 회화나무꽃 추출물 첨가량, 유화시간, 유화속도 등을 설정하고, 반응치로는 O/W 유화액의 평균액적크기(MDS), 점도 및 유화안정도지수(ESI)를 설정하였다. BBD-RSM 최적화 분석결과 세 가지 반응치를 동시에 부합하는 최적조건은 유화시간(17.8 min), 유화속도(5505 rpm), 유화제의 첨가량(2.28 wt.%), 회화나무꽃 추출물 첨가량(1.05 wt.%)으로 산출되었으며, 이 조건에서의 BBD-RSM 예측결과는 MDS (1875.5 nm), 점도(1789.7 cP), ESI (93.8%)로 얻었다. 또한 이 조건에서 실제 실험을 통해 얻은 결과는 이론 결과에 비래 평균오차율은 5% 이하로 나타났다. 따라서 본 연구에서 BBD-RSM 최적화 분석을 적용할 경우 비교적 높은 유의수준의 만족하는 결과를 얻을 수 있었다.
