Lanostane triterpenoids from the mushroom Naematoloma fasciculare.
In our continuing search for structurally interesting and bioactive metabolites from Korean wild mushrooms, bioassay-guided fractionation and a chemical investigation of the MeOH extracts of the fruiting bodies of the mushroom Naematoloma fasciculare resulted in the isolation of four new lanostane triterpenoids (1-4), together with 11 known compounds (5-15). The structures of 1-5 were determine...

The management of postprandial hyperglycemia is an important strategy in the control of diabetes mellitus and complications associated with the disease, especially in the diabetes type 2. Therefore, inhibitors of carbohydrate hydrolyzing enzymes can be useful in the treatment of diabetes and medicinal plants can offer an attractive strategy for the purpose. Vaccinium arctostaphylos leaves are c...
متن کاملBioassay-Guided Isolation and Evaluation of Antiproliferative Effects of (Z)-Ethylidene-4, 6-Dimethoxycoumaran-3-One from Pogostemon Quadrifolius (Benth.)
The aim of the study was to isolate and identify the major cytotoxic principle from plant leaves of Pogostemon quadrifolius (Benth.) and evaluate its antiproliferative potential against human cancer cells. Plant leaves were extracted sequentially with a soxhlet apparatus, using petroleum ether, chloroform and methanol solvents. Petroleum ether and chloroform extracts exhibited antiproliferative...
