alpha peltatin/podophyllum

In an effort to develop a sustainable source of podophyllotoxin for the production of anticancer drugs such as etoposide, teniposide and etopophos, Podophyllum peltatum accessions with podophyllotoxin-rich leaf biomass were identified and transplanted to different growing conditions by vegetative

A new rapid UPLC-UV-MS method has been developed that permits the analysis of four lignans (4'-O-demethylpodophyllotoxin, podophyllotoxin, α-peltatin and β-peltatin) in P. peltatum L. Podophyllotoxin is a natural lignan that is being used as a precursor for the semi-synthetic anti-cancer drugs

The antiviral activity of an aqueous extract of Podophyllum peltatum was investigated. The extract was fractionated by reversed-phase chromatography, and podophyllotoxin was found to be the most active component in inhibiting the replication of measles and herpes simplex type I viruses.

Dysosma versipellis (Hance) is a famous traditional Chinese medicine for the treatment of snakebite, weakness, condyloma accuminata, lymphadenopathy, and tumors for thousands of years. In this work, four podophyllotoxin-like lignans including 4'-demethylpodophyllotoxin (1), α-peltatin (2),

This study was conducted to investigate the chemical constituents in the root of Dysosma versipellis(Hance) M. Cheng. The constituents were isolated by silica gel, lichroprep RP-C(18) and pharmadex LH-20 column chromatography and the IR, MS, NMR, 2D-NMR spectroscopic analysis were employed for the
