Two new lanostane triterpenoids fromPoria cocos

Journal of Asian Natural Products Research, 2008
Two new lanostane triterpenoids, 29-hydroxypolyporenic acid C (4) and 25-hydroxypachymic acid (5), together with three known compounds, ergosta-7,22-dien-3beta-ol (1), polyporenic acid C (2) and pachymic acid (3), were isolated from the 95% ethanolic extract of the sclerotium of Poria cocos (Schw.) Wolf.

Lanostane triterpenes isolated from epidermis of Poria cocos

Phytochemistry Letters, 2017
Abstract Four new lanostane triterpenes together with twenty-two known lanostane triterpenes were isolated from the epidermis of Poria cocos . The chemical structures of all compounds were determined mainly by 1D and 2D-NMR spectrometry. Three of the new compounds ( 5 , 10 and 24 ) were evaluated for cytotoxic activities against human gastric ...

Poria cocos polysaccharides attenuate chronic nonbacterial prostatitis by targeting the gut microbiota: Comparative study of Poria cocos polysaccharides and finasteride in treating chronic prostatitis

International Journal of Biological Macromolecules, 2021
Finasteride is an antiandrogenic drug used for the clinical treatment of chronic nonbacterial prostatitis (CNP). Recently, we reported the anti-CNP activity of Poria cocos polysaccharides (PPs) in a rat model. In this study, we compared the differences between PPs and finasteride in treating CNP, especially their effects on the gut microbiota.

Novel Parkin agonists from Poria cocos against dyslipidemia

Fitoterapia
Parkin, a cytosolic E3 ubiquitin ligase, plays a crucial role in targeting damaged mitochondria. The dysfunction of Parkin has been implicated in various diseases, including dyslipidemia, highlighting the significance of regulating Parkin activity for therapeutic interventions.

An LC Fingerprint Study of Poria cocos (Schw.) Wolf

Chromatographia, 2009
The aim of the paper was to establish an efficient and accurate fingerprint method for the identification and quality control of Poria cocos (Schw.) Wolf. Methanol extracts of 43 samples of sclerotium and five samples of tegument were analysed by LC with photodiode array detection.

Phytochemical and chemotaxonomic study of Poria cocos (Schw.) Wolf

Biochemical Systematics and Ecology, 2019
Abstract A new lanostane-type triterpene, 6α-hydroxy-dehydrotumulosic acid (1), together with 12 known compounds (2–13), was isolated and characterized from the sclerotium of Poria cocos. Their structures were confirmed by 1D and 2D NMR spectroscopic methods and by comparison with values previously reported in the literature.

[Triterpenes isolated from Poria cocos by derivazations].

Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2004
The separation of triterpene acids was achieved from Poria cocos (Schw.) Wolf by TLC after treatment with Ph2CNN or RX under mild condition followed by selective hydrolysis of ester groupings. Three triterpene acids, 3 beta-acetoxyl-16 alpha-hydroxy-lanosta-8,24(31)-diene-21-oic acid (I), 3-oxo-16 alpha-hydroxy-lanosta-7,9(11), 24(31)-trien-21-oic acid

[Study on quality standard of Poria cocos].

Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2009
To perfect the standard of Poria cocos (Schw.).TLC and HPLC fingerprint were used to identify triterpenoids from P. cocos. The content of pachymic acid and dehydropachymic acid were determined by HPLC.Pachymic acid showed a good linear relationship at a range of 1.52 - 7.60 microg/ml, r = 0.9994, the average recovery was 96.90%, RSD = 1.09 ...

Triterpenes from the surface layer of Poria cocos

Phytochemistry, 1995
Abstract The surface layer of Poria cocos has yielded five new triterpenes; two of the lanostane type and three of the 3,4-secolanostane type. The structures of these compounds were elucidated mainly by two-dimensional NMR techniques.
