objectives: We investigated the moisturizing and cooling effects of the cosmetic product with Scrophularia Buergeriana, Poria Cocos, Lonicera Japonica, Portulaca Oleracea and Ginko Biloba extract on human skin by using non-invasive instrument. Methods: We measured physiological effects after volunteers(female, n=5) applied the cosmetic product containing the extract of oriental herbs. The forearm skin moisturization was measured with $Corneometer^{\circledR}$ CM825 after 15min, 3hr, and 6hr. The forearm skin surface roughness was with Scanning electron microscopy after 15min, and 6hr. The face skin temperatures cooling and microcirculation effects were measured with ThermaCAMTM PM525 and LDl-Periscan PlM II after 15min, and 30min. Results: The forearm skin moisturization was imcreased 108% after 15min. The forearm skin surface roughness was decreased significantly after 15min. The face skin temperatures were cooling down to $30.7^{\circ}C$. The face skin microcirculation effect was normalized time-dependently. Conclusions: We concluded that cosmetic product containing the extract of Scrophularia Buergeriana, Poria Cocos, Lonicera Japonica, Portulaca Oleracea and Ginko Biloba had a moisturization effect and improving the surface roughness, temperature and microcirculation on the human skin.

Both Portulaca oleracea (PO) and Glechoma hederacea (GH) have been used as traditional medicine due to the multiple pharmacological activities. However, the effects of PO and GH in the pathology of periodontitis is still elusive. In this study, we examined anti-microbial activity of PO ethanol extract (POEE) and GH ethanol extract (GHEE) in vitro, and physiological effects of POEE and GHEE on the cell inflammatory responses and the severity of periodontitis were determined using the rat periodontitis model. Our results indicate that POEE and GHEE had no effects on the proliferation of streptococcus mutans and on LPS-mediated inflammatory responses in gingival fibroblast cells. Notably, ingestion of POEE and GHEE resulted in attenuating the severity of periodontitis and population change of immune cells. These data suggests that PO and GH should be considered as candidates for relieving the severity of periondontitis.

Extracts of common purslane(Portulaca oleracea L.) showed to possess some antifungal substances which inhibited the mycelial growth of the phytopathogenic fungi tested;Valsa mali, Alternaria kikuchiana and Pyricularia oryzae. These antifungal substances were found to be soluble in methanol and were regarded as kinds of lipid. In order to isolate the antifungal substances, the extracts of common purslane were concentrated by evaporation under reduced pressure and extracted with methanol The methanol solution was subjected to silica gel-florisil column and divided into lipid and non-lipid fractions. Lipid fractions only showed antifungal activity against the fungi tested. The effective substances contained in the extracts of common purslane inhibited not only the mycelial growth but also the spore germination of the fungi.

As a result of screening search for biologically active substances to weed seeds among higher plants, MeOH extract from Rhathiolepis ovata Briat was found to inhibit germination of test weeds considerably. In the course of purifying the active substances, pinoresinol which showed very similar behavior with the active fraction on various chromatographies, was isolated from the same source, spectrally identified and bioassayed. Pinoresinol exhibited germination inhibitory activity against the common purslane (Portulaca oleracea L.) only ; the inhibitory effect was about 55% at concentration of 5 mg/ml.

This study was performed to investigate the antimicrobial effect of Sophora angustifolia extracts against food-borne pathogens. First, Sophora angustifolia was extracted with methanol at room temperature, and the methanol extracts from Sophora angustifolia were fractionated using petroleum ether, chloroform, ethyl acetate, and methanol. The antimicrobial activity of the Sophora angustifolia extracts was determined using the paper disc method against food-borne pathogens and food spoilage bacteria. The methanol extracts of Sophora angustifolia showed the highest antimicrobial activity against Staphylococcus aureus and Salmonella typhimurium. A synergistic effect was found in the combined extracts of Sophora angustifolia and Portulaca oleracea, compared to the activity of each extract alone. Finally, the growth inhibition curve was determined using the methanol extracts of Sophora angustifolia against Staphylococcus aureus and Salmonella typhimurium. The methanol extract of Sophora angustifolia showed strong antimicrobial activity against Staphylococcus aureus at a concentration of 5,000 ppm. The 5,000 ppm methanol extract from Sophora angustifolia retarded the growth of S. aureus for more than 24 hours and of Salmonella typhimurium for up to 12 hours.

This study assessed the effects of treatment with sap extract from onion residues postharvest and purslane on the quality and quantity of organic onions. At the bending stage, onions treated with the sap extract showed vigorous growth, with higher plant heights, more leaves, and longer sheath lengths than untreated onions. The onion yield was significantly increased when the plant was treated with extracted sap as compared with that of untreated plants (p<0.05). The bulb weight distribution of onions in the mixed onion and purslane treatment was also significantly increased (~300 g) as compared with that of the other treatment (p<0.05). Except for CaO and S, the mineral content of the onions produced from plants treated with the onion and purslane extract mixture was higher than those of onions in the other treatment. The hardness of onions produced from plants treated with the onion and purslane extract was significantly increased (8% and 20%, respectively) as compared with that of onions produced from plants treated with the onion extract only or no treatment (p<0.05). However, there was no significant difference in the sugar contents of the onions produced from extract-treated and nonextract-treated plants. Postharvest, the content of inorganic components (phosphate, calcium, sulfuric acid, and manganese) was higher in soil treated with the onion extract than in soil treated with the onion and purslane extract and non-treated soil. It can be concluded that residues left after onion harvests and purslane extract can be used as natural and environmentally friendly materials for the cultivation of organic onions.

쇠비름(Portulaca oleracea L.)은 쇠비름과(Portulacaceae)에 속하는 일년생 초본으로 우리나라 각지에 5~9월에 걸쳐 자생하고 있다. 한국보다는 중국에서 식용으로 애용되고 있으며, 해열, 이뇨, 산혈 등의 효능이 있어 임질, 요도염, 유종, 대하증, 임파선염 등에 약용으로 사용하고 있다. 쇠비름의 성분으로는 vitamin $B_1$ 및 C, saponin, tannin, flavonoid, dopamine, noradrenalin 등이 보고되었다. 쇠비름에 관한 연구로는 항산화효과, 항균효과 및 해독효과가 발표되었으나, 고지혈증에 관한 연구는 미흡한 실정이다. 따라서 본 연구에서는 고콜레스테를 유발식이에서 쇠비름 에탄을 추출물이 혈청 중 지질에 미치는 영향에 대해 검토하고자 하였다. 실험동물은 6주령의 Sprague Dawley 흰쥐 수컷을 각 실험군당 10마리씩, AIN-93M을 기본으로 하여 대조군(고지방식이), 쇠비름 에탄올 추출물 투여군의 3군(고지방식이+25mg/kg, 75mg/kg, 125mg/kg)으로 나누어 4주간 실험 식이를 급여하고 사육기간 중 사료 섭취량, 체중증가율, 식이효율을 측정하였다. 실험 종료 후, 혈액을 채취하여 혈액에서의 total lipid, total cholesterol, triglyceride, HDL-cholesterol은 효소법을 이용한 kit(아산제약)을 사용하여 측정하였고, 심혈관계 질환의 위험도에 이용되는 동맥경화지수는(atherogenic index, AI) 계산식을 이용하여 산출하였다. 실험결과, 최종체중, 체중증가율, 식이효율 및 장기무게는 실험군 간의 차이를 나타내지 않았다. 그러나 고지방식이에 쇠비름 에탄올 추출물을 125mg/kg의 농도로 병합 투여했을 때 혈중의 total lipid, total cholesterol 및 triglyceride는 대조군에 비해 유의적으로 감소하였으며, 고지방식이에 의해 증가된 동맥경화지수도 대조군에 비하여 유의적으로 저하되었다. 그리고 고지방식이로 증가된 ALT 및 AST 활성이 쇠비름 에탄올 추출물 투여로 유의적으로 감소하였다. 따라서 쇠비름 에탄올 추출물은 혈청 중 지질 개선 효과와 간 기능 개선효과가 있는 것으로 사료되나, 어떤 성분이 콜레스테롤 저하 효과를 나타내는지 보다 자세한 연구가 요구되어 진다.

The antioxidative effect of the 75% ethanol extracts of preliminary selected Fritillaria ussuriensis Max(Fs), Houttuynia cordata Thunb(Hc), Portulaca oleracea L.(Po) and Perilla frutescene Var javanica Hara cake(Pf) were tested on palm oil and lard by rancimat test. Each solvent fraction of chloroform, ethyl acetate(EtOAc), butanol and water, was also evaluated its antioxidative effect with some synergists, like as ascorbic acid, citric acid and ${\delta}-tocopherol$. Po extract showed higher antioxidative effect on lard and the fraction of all test plants were the most effective on palm oil and lard with ascorbic acid and ${\delta}-tocopherol$. When 200 ppm of EtOAc fraction of Fs, He and Po extract each with 200 ppm of ascorbic acid were added to palm oil, the antioxidative index(AI, induction time of oil containing each extract/induction time of test oil) were 1.60, 1.53 and 1.47 respectively and 200 ppm of EtOAc fraction of Po and Pf extract each with 200 ppm of tocopherol to lard, the AI were 3.19 and 3.63 respectively.

A study has been conducted to investigate the radioprotective effects of purslane extracts (P) when i.p. injected before irradiation (R). For studying the amino acid composition, three groups of ICR mice (7-week-old) were tested. The first group i.p. injected with purslane extract for 5 days were irradiated with 6 Gy of ${\gamma}$-radiation (P+R). The second group was irradiate with 6 Gy without any pretreatment (R). The third group was non-irradiated control (CT). Each group divided into two groups for the survival rate study, one injected with saline (S) and the other injected with purslane extract (P) for five days and then irradiated with 8 Gy. The amino acid composition of urine samples were analyzed with HPLC for 19 days after irradiation. A few kinds of amino acids such as lysine and methionine in urine from P+R group increased in comparison with those from CT or R group. The survival rate of P group maintained much higher than that of S group during experimental period. The results obtained may support that this plant has radioprotective substances by means of life-lengthening, not of urine amino acid components.
