Six lanostane-type triterpene acids were isolated from the fruiting bodies of Piptoporus betulinus. They were identified as polyporenic acids A (1) and C (2), three derivatives of polyporenic acid A (3-5), and a novel compound, (+)-12α, 28-dihydroxy-3α-(3

The chirality of the acyl group 8′-O-(3-Hydroxy-3-methylglutaryl)- 8′-hydroxyabscisic acid was revised to S based on an HPLC analysis of the diastereomer derived from mevalonolactone obtained by reduction of the conjugate with lithium borohydride. 8′-O-(3

The fruits of Citrus unshiu are one of the most popular and most enjoyed fruits in Korea. As we continue to seek for bioactive metabolites from Korean natural resources, our study on the chemical constituents of the fruits of C. unshiu resulted in the isolation of a new flavonoid glycoside, limocitrunshin 1, along with seven other flavonoids 2-8 and a limonoid 9. All structures were identified by spectroscopic methods, namely 1D and 2D NMR, including HSQC, HMBC, and 1H-1H COSY experiments, HRMS, and other chemical methods. Compounds 3, 5, and 9 are reported to be isolated from this fruit for the first time. The isolated compounds were applied to activity tests to verify their inhibitory effects on inflammation and nephrotoxicity. Compounds 6 and 9 showed the most potent inhibitory activity on renal cell damage and nitric oxide production, respectively. Thus, the fruits of C. unshiu could serve as a valuable natural source of bioactive components with health benefits for potential application in functional foods.

In Alzheimer's disease, amyloid-β (Aβ) accumulation in the brain results in neuronal cell death and is one of the major causes of dementia. Because the current therapeutic agents are not yet sufficiently effective or safe, there have been attempts to find
C-Methylated flavanones from the rhizomes of Matteuccia intermedia and their α-glucosidase inhibitory activity
