The Occurrence of Tuckahoes and Poria Cocos in Florida
Mycologia, 1929The sclerotia of Poria Cocos (Schw.) Wolf occur in Florida, especially in the sandy soils. The fruiting stages were developed in pure culture from portions of the inner contents of the sclerotia re...

Two new lanostane triterpenoids fromPoria cocos
Journal of Asian Natural Products Research, 2008Two 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.

[Study on quality standard of Poria cocos].
Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2009To 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 ...

Phytochemical and chemotaxonomic study of Poria cocos (Schw.) Wolf
Biochemical Systematics and Ecology, 2019Abstract 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 from the surface layer of Poria cocos
Phytochemistry, 1995Abstract 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.

Lanostane triterpenes isolated from epidermis of Poria cocos
Phytochemistry Letters, 2017Abstract 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 ...

Nematicidal activity and chemical component of Poria cocos.
Journal of microbiology (Seoul, Korea), 2005Poria cocos, a famous traditional Chinese medicine, was found to have nematicidal activity in experiments searching for nematicidal fungi. The experiment showed it could kill 94.9% of the saprophytic nematode, Panagrellus redivivue, 92.6% of the root-knot nematode, Meloidogyne arenaria, and 93.5% of the pine nematode, Bursaphelenchus xylophilus, on PDA
