Screening and Analysis of the Potential Bioactive Components of Poria cocos (Schw.) Wolf by HPLC and HPLC-MS(n) with the Aid of Chemometrics.
The aim of the present study was to establish a new method based on Similarity Analysis (SA), Cluster Analysis (CA) and Principal Component Analysis (PCA) to determine the quality of different samples of Poria cocos (Schw.) Wolf obtained from Yunnan, Hubei, Guizhou, Fujian, Henan, Guangxi, Anhui and Sichuan in China. For this purpose 15 samples from the different habitats were analyzed by HPLC-...
متن کاملCloning and Characterization of Farnesyl Diphosphate Synthase Gene Involved in Triterpenoids Biosynthesis from Poria cocos
Poria cocos (P. cocos) has long been used as traditional Chinese medicine and triterpenoids are the most important pharmacologically active constituents of this fungus. Farnesyl pyrophosphate synthase (FPS) is a key enzyme of triterpenoids biosynthesis. The gene encoding FPS was cloned from P. cocos by degenerate PCR, inverse PCR and cassette PCR. The open reading frame of the gene is 1086 bp i...
متن کاملChemical constituents and pharmacological properties of Poria cocos.
Poria cocos (Polyporaceae) is a saprophytic fungus that grows in diverse species of Pinus. Its sclerotium, called fu-ling or hoelen, is used in traditional Chinese and Japanese medicine for its diuretic, sedative, and tonic effects. Various studies of this fungus have demonstrated its marked anti-inflammatory activity in different experimental models of acute and chronic inflammation. It is wid...
متن کاملAdvanced ultra-performance liquid chromatography-photodiode array-quadrupole time-of-flight mass spectrometric methods for simultaneous screening and quantification of triterpenoids in Poria cocos.
A sensitive, precise and accurate method was developed to screen and quantify triterpenoids based on ultra-performance liquid chromatography-photodiode array-quadrupole time-of-flight mass spectrometry (UPLC-PDA-QTOF-MS). An exact neutral loss scan of 62.0004 Da (CH2O3) was used to selectively detect triterpenoids in Poria cocos, followed by a survey scan for exact masses of precursor and fragm...

Poria cocos WOLF), belonging to the Polyporaceae in basidiomycetes, forms sclerotia on the roots of such trees as pine, cedar, fir and oak. The major host plant of this fungus in Japan, China and Korea is the pine and the dried sclerotium of W. cocos is called “Bukuryo” in Japanese. In the Japanese Pharmacopoeia, the external layer is usually mostly removed. It is one of the most important crud...
