당뇨병환자의 식후 고혈당을 조절하고자 가장 많이 사용되고 있는 약제가 "알파글루코시다제 억제제"라는 당분 흡수 억제제이다. 이는 복합탄수화물의 흡수를 지연시켜서 식후 고혈당의 폭을 감소시킨다.

인슐린의존형당뇨병 환자의 혈당조절의 방법으로 먼저 식이요법과 운동이 권장되며, 이러한 방법으로 혈당조절이 만족스럽지 않을 때 경구혈당강하제를 사용하는 것은 혈당조절과 합병증 예방에 중요한 역할을 할 수 있다. 국내에서는 경구혈당강하제로 설폰요소제, 비구아나이드제인 메트포르민(metformin) 및 알파글루코시다제(${\alpha}$-glucosidase) 억제제인 아카보스(acarbose) 등이 사용되고 있다. 새로 개발중인 트로글리타존, 지방산 산화 억제제 등의 약제는 아직 임상에서 널리 사용되고 있지는 않다.

The objective of this study was to evaluate the bifidogenic effect and a-glucosidase inhibitory effect of artificially cultured Phellinus linteus. The water extract of P. linteus promoted the growth of Bifidobacterium breve as well as the decrease of final pH in the media culturing intestinal bacteria. The growth of lactic acid bacteria inhibited effectively the bacterial enzymes, ${\beta}-glucosidase,\;{\beta}-glucuronidase$ and tryptophanase, of intestinal bactetria. The water extract of P. linteus inhibited maltase, sucrase and ${\alpha}-amylase$ of rat intestine.

Trafficking process of viral glycoprotein to cell surface results in the syncytium formation when baby hamster kidney (BHK) cells was infected by Newcastle disease virus (NDV). Rhus chinensis gall, well-known as a medicinal plant, inhibited not only syncytium formation, but also trafficking of glycoprotein, hemagglutinin-neuramidase (HN) to the cell-surface. Modification of viral glycoprotein is processed within the endoplasmic reticulum and golgi body during trafficking into surface. R. chinensis gall extracts showed the strong inhibitory activities ($IC_{50}$ $12.5{\mu}g/mL$) against ${\alpha}-glucosidase$, when compared with the ${\beta}-glucosidase$. And this inhibitory activities is increased by the samples in a dose-depedent pattern. These data showed that the extracts of R. chinensis gall inhibited the cell-surface expression of NDV-hemagglutinin-neuramidase glycoprotein without significantly affecting HN glycoprotein synthesis in NDV-infected BHK cells.

Extracts from Schizandra chinensis Baillon (Korean name: Omija) were tested for antioxidant and their inhibitory activities of ${\alpha}-amylase$ and ${\alpha}-glucosidase$. Total contents of phenolics were found as 4.35 mg/g (water extract)${\sim}$6.35 mg/g (60% ethanol extract). Electron donating ability (EDA), ABTS [2,2'-azinobis(3-ethyl-benzothiaznoline-6-sulfonic acid)] radical decolorization, antioxidant protection factor (PF) and thiobarbituric acid reactive substance (TBARS) were measured for the antioxidative activity of the extracts from S. chinensis. The water extract were determined as 97.5% at 200 ${\mu}g/ml$ while the activity of 60% ethanol extract were 96.2% at 200 ${\mu}g/ml$ in EDA. The 60% ethanol extract showed higher antioxidant activity than water extract when evaluated by ABTS radical decolorization, antioxidant PF and TBARS. ${\alpha}-Amylase$ inhibitory activity of water extract was similar with that of 60% EtOH extract. ${\alpha}-glucosidase$ inhibitory activities of water extract (97.4%) was higher than that of 60% ethanol extract (84.5%) at 200 ${\mu}g$/ml. The water extract from S. chinensis did not show an antimicrobial activity against Helicobacter pylori, but the 60% ethanol extract showed high antimicrobial activities such as 23 ${\pm}$ 1.6 mm of clear zone in 200 ${\mu}g/ml$ of phenolics. The result suggest that the water and 60% ethanol extract from S. chinensis will be useful as natural antioxidants and functional foods.
