Chemistry and biological activities of caffeic acid derivatives from Salvia miltiorrhiza.
The structural diversity and the pronounced biological activities encountered in the caffeic acid derivatives of S. miltiorrhiza indicate that this class of compounds is worthy of further studies that may lead to new drug discovery. Expand
Polyphyllin D is a potent apoptosis inducer in drug-resistant HepG2 cells.
It is shown for the first time that PD is a potent anticancer agent that can overcome drug resistance in R-HepG2 cells and elicit programmed cell death via mitochondrial dysfunction. Expand
A comparative study on aqueous root extracts of Pueraria thomsonii and Pueraria lobata by antioxidant assay and HPLC fingerprint analysis.
The HPLC method developed and chemical markers 1-6 can be used for the rapid identification and evaluation of Radix Puerariae herbs and their aqueous supplements, and the results of this investigation support the use of pueraria lobata and Puerria thomsonii in the clinic application and as dietary supplement, respectively.

On the absolute structure of optically active neolignans containing a dihydrobenzo[b]furan skeleton
Abstract Several optically pure neolignans containing a dihydrobenzo[b]furan skeleton were synthesized. Based on an X-ray crystallographic study and circular dichroism results, the absolute… Expand
Pheophorbide a, an active compound isolated from Scutellaria barbata, possesses photodynamic activities by inducing apoptosis in human hepatocellular carcinoma
Pa-PDT treatment could reduce the tumor size by 57% after 14 days treatment in nude mice model and the cytotoxic effect could be reversed when ascorbic acid was applied. Expand

Metal-betaine interactions—VI. Crystal and molecular structure of tetrakis(betaine)copper(II) nitrate, [Cu(Me3NCH2COO)4](NO3)2
Abstract The crystal and molecular structure of [Cu(BET)4]·(NO3)2 (BET= Me3N+CH2COO−) has been established by X-ray crystallography. The complex consists of discrete [Cu(BET)4]2+ and nitrate anions,… Expand
Pheophorbide a, a major antitumor component purified from Scutellaria barbata, induces apoptosis in human hepatocellular carcinoma cells.
Mechanistic studies showed that pheophorbide a induced apoptosis in Hep3B cells, a viral-induced hepatoma cell line, but it was found to be non-toxic in normal human liver cells WRL-68 and the anti-proliferative activity and possible mechanisms of action are discussed. Expand

Excess volatile acid/base not only affords full conversion in nonstoichiometric acid–base reaction route but also permits its facile removal for stoichiometric purification, resulting in average efficiency of 16.1% in forward/reverse scans. Expand
Molecular structures and π–π interactions of some flavonoids and biflavonoids
Abstract The molecular structures of two flavones, wogonin (1) and mikanin (2), and two biflavonoids, cupressuflavone (3) and neochamaejasmin A (4), were determined by single-crystal X-ray analysis.… Expand
