OBJECTIVE
To investigate the chemical constituents of Carya cathayensis and their antitumor bioactivity.
METHODS
The compounds were isolated by Sephadex LH-20 and silica gel column chromatography. Their structures were identified by physicochemical properties and spectroscopic analysis. Then their
A new lignan (7R,8S,8'R)-4,4',9-trihydroxy-7,9'-epoxy-8,8'-lignan, and three new phenolics, carayensin-A, carayensin-B, and carayensin-C, together with 13 known compounds were isolated from the shells of Carya cathayensis. Their chemical structures were established mainly by 1D and 2D NMR techniques
This study aimed to find cytotoxic chemical constituents from Carya cathayensis leaves (LCC) by using various chromatographic procedures. Identification of the chemical constituents was carried out by various spectroscopic techniques and classical chemical methods. The cytotoxic activity of the
Carya cathayensis is a fruit-bearing plant that belongs to the Juglandaceae family and is widely distributed throughout the world. It possesses various important biological activities. We have previously isolated an antitumor compound from the shell of C. cathayensis fruits and named it E2S
The molecular mechanism of Juglone-induced cell cycle arrest and apoptosis in human endometrial cancer cells was investigated. Juglone was purified from the green husk of Carya cathayensis Sarg and identified by HPLC, LC-MS/MS, and NMR. At an IC50 of 20.81 μM, juglone significantly
BACKGROUND
In Brazil many health disorders are treated with the consumption of different varieties of tea. Shell extracts of pecan nut (Carya illinoinensis), which have significant amounts of phenolic compounds in their composition, are popularly taken as tea to prevent diverse
