In the present study, in attempt was made to observe the effect of lipid components in pantocrin and antler velvet and sponge layers extracts on the aldolase activity in the rat spinal nerves. The antler chloroform-methanol (2:1) extracts are known to be composed of neutral lipids, cholesterol, cerebrosides, spingomyelin, phosphatidyl choline, phosphatidyl ethanolamine, phosphatidyl serine and gangliosides. The antler extracts were studied on the aldolase activity in the rat spinal nerves. The aldolase activity was measured by the method of Lehninger. To investigate the components of tile extracts which affect the enzyme activity, the chloroform-methanol (2:1) extracts of antler were fractionated into petroleum ether soluble and insoluble fractions and their effects on the enzyme activity were compared. It was found that the chloroform-methanol (2:1) extracts of the antler sponge and velvet layers as well as those petroleum ether soluble fractions obtained from the chloroform-methanol (2:1) extracts, decrease the aldolase activity by 18-23%. However, pantocrin showed increasing effect on the aldolase activity by 42.6%. The petroleum ether insoluble fraction of the chloroform-methanol (2:1) -extract showed no significant increasing activity (about 13%) on the spinal nerves aldolase. The components of pantocrin ind the petroleum ether insoluble fractions were attempted to analysize by thin layer (silica gel) and gas liquid chromatography.

전처리 조건을 달리하여 얻은 추출물의 일반성분을 측정한 결과, 수분은 비열처리-효소 추출구보다 열처리-효소 추출구가 다소 높았으며, 조회분과 조펙틴은 유의적인 차이가 없었다. 상등액 추출율은 celluclast와 pectinex의 효소처리 했을때 무열처리-효소 추출구보다 열처리-효소 추출구가 다소 높게 나타났다. 젤리의 adhesiveness 값은 열처리-효소 추출구 일수록 그리고 Celluclast 효소만 처리했을 때 높게 나타났다. Celluclast 효소를 첨가하여 제조한 젤리에서만 값들이 증가하는 경향을 나타냈고 나머지 Pectinex 효소나 혼합효소를 첨가하여 제조한 젤리에서는 값들이 모두 감소하는 결과를 나타냈다. 비열처리-효소 추출구에서는 Celluclast효소와 Pectinex효소를 첨가하여 제조한 젤리는 커다란 차이를 보이지 않았지만 혼합효소를 첨가하여 제조한 젤리에서는 L값이 높은 증가율을 나타냈고 a값은 녹색도를 나타내는 (-)값이 더 증가하였다. 열처리-효소 추출구 젤리가 비열처리-효소 추출구 젤리보다 맛과 조직감 면에서는 약간 우수하였으나 다른 항목들에서는 보편적으로 비열처리-효소 추출구 젤리가 더 나은 결과를 나타냈다.

In this study ethanol extracts of aerial part of Geranium thunbergii Sieb. et Zucc. was investigated for their ability to inhibit a-glucosidase, and thus was fractionated using two organic solvents, including dichloromethane, ethyl acetate. The ethyl acetate-soluble fraction, which manifested potent enzyme inhibitory properties, was then followed by tracking down the active compound by combining HPLC micro-fractionation to an enzyme assay in 96-well plate. The ${\alpha}$-glucosidase inhibitory activity profile showed that two peaks exhibited potent inhibitory activity, and then the structural analyses of the two peaks were carried out by HPLC-UV-MS. The main ${\alpha}$-glucosidase inhibitory compounds in the ethyl acetate-soluble fractions of ethanol extracts of Geranium thunbergii Sieb. et Zucc. were tentatively identified as geraniin and kaempferol-7-rhamnoside.

To enhance the efficacy of Abeliophyllum distichum leaves, extracts were prepared using different solvents for hydrolytic enzyme-treated Abeliophyllum distichum leaves. Physicochemical quality and antioxidant activity were measured. Soluble solids, reducing sugar, ascorbic acid, flavonoids, and polyphenols contents showed the lowest values in the control without enzyme treatment. However, they showed high contents in ethanol extract. In the case of enzyme treatment, their values were higher than those of the control. In particular, verbascoside content increased about 220 times more than that of the control group when treated with enzymes and extracted with 50% ethanol. pH was lowered upon enzymatic treatment. Regarding DPPH radical scavenging activity, for enzyme-free, 25% ethanol extract showed the highest activity among extracts with different solvents. For cellulase and pectinase-treated leaves, water extract showed the highest DPPH radical scavenging activity among extracts with different solvents. For leaves treated with enzyme combination, 50% ethanol extract showed the highest DPPH radical scavenging activity among extracts with different solvents. Regarding ABTS radical scavenging activity, it was generally higher in the 50% ethanol extract than in the water extract and 25% ethanol extract. In particular, verbascoside content was increased when the extract was prepared by co-treatment with enzymes and 50% ethanol.

Mulberry extracts can be incorporated into skin-whitening products. The compound attributed to lighten the skin is arbutin, a form of hydroquinone that inhibits melanin release by suppressing the tyrosinase enzyme. For the cosmetic applications, the physiological effects of mulberry (Morus alba) extracts were investigated. The water soluble fraction of mulberry contains higher amount of protein (16.28~4.47%) in contrast to fat (1.55~1.41%). In addition, the fraction abundantly contains succinic acid (972.4-275.8 mg/g) and phosphoric acid (1,628.4-121.9 mg/g) in different parts of mulberry. The free radical scavenging ability in water soluble fraction was found to display remarkable effects in comparison with methanol and ethyl acetate fraction. The ethyl acetate-soluble of root and leaf showed remarkable tyrosinase inhibition activity by IC 50 (${\mu}g/ml$). The anticancer activity of methanol fraction obtained from mulberry using human cancer cell lines showed growth inhibition effect (270.14 mg/ml in Calu-6 cells, 295.29 mg/ml in HCT-116, and 332.29 mg/ml in MCF-7 cells, respectively). Based on the results, Morus alba extracts include cosmetic ingredients with antioxidizing and whitening properties.
