Effects of batatasins I, III and V, phenolic growth inhibitors occuring in dormant bulbils of Dioscorea batatas Decne., on photosynthetic reactions of chloroplasts from spinach (Spinacia oleracea L.) and on respiration of mitochondria from potatoes (Solanum tuberosum L.) were investigated. In
To find anti-inflammatory compounds from the tuberous roots of Dioscorea batatas, we isolated 6-hydroxy-2,4,7-trimethoxyphenanthrene (batatasin I) from the dichloromethane (CH(2)Cl(2)) fraction of this plant. Batatasin I inhibited both the generation of prostaglandin D(2) (PGD(2)), leukotriene C(4)
Three growth inhibitors, for which the names batatasins I, II and III are proposed, occur in dormant yam bulbils. Application of these inhibitors suppresses the sprouting of bulbils, and the inhibition is reversible by low-temperature stratification. Batatasins I and III were isolated as crystals
OBJECTIVE
To study the chemical constituents in the tubers of Dioscorea bulbifera.
METHODS
Compounds were isolated and purified with silica gel, ODS and Sephadex LH-20 column chromatography, their structures were determined by using spectroscopic methods including MS and NMR.
RESULTS
Fourteen
We previously reported the lipase inhibitory activity of the n-BuOH fraction of Dioscorea opposita (DOB) and its isolates. This study sought to evaluate their anti-adipogenic activity in terms of their effects on the adipogenic transcription factors peroxisome proliferator-activated receptor γ
Dioscorea opposita Thunb, commonly known as "yam" that has a long dietary therapy history for diabetes, is widely consumed as a botanical dietary supplement and widely cultivated in China. In this work, a method for rapid screening of α-glucosidase inhibitors from Dioscorea opposita Thunb peel
Present study aimed to immobilise the α-glucosidase on suitable supports to construct enzymatic microreactors and their subsequent applicability in efficient inhibitor screening from the Chinese Yam (Dioscorea opposita Thunb.) peel. A type of lamellar and porous composites (rGO@Fe3O4) were
Dioscorea opposita Thunb. cv. Tiegun (DTT), a type of homologous medicinal plant, is commonly used as food in daily life. However, there has always been confusion regarding removal of the peel, as the nutrient metabolite composition of the peel is unclear. Here, a nuclear magnetic resonance
In order to rapidly screen α-glucosidase (α-GLU) inhibitors from Chinese herbs extract, an online screening method was developed by using enzymatic microreactors in combination with HPLC. A type of dodecahedral and porous material (ZIF-90) was synthesized at room temperature and employed as supports
