Xing-Cong Li,Alpana S. Joshi,Hala N. ElSohly,Shabana I. Khan,Melissa R. Jacob,Zhizheng Zhang,Ikhlas A. Khan,Daneel Ferreira,Larry A. Walker,Sheldon E. Broedel,Robert E. Raulli,Ronald L. Cihlar +11 more
TL;DR: Three'-Formylgenistein and ellagic acid 4-O-alpha-l-rhamnopyranoside were the most potent compounds against FAS, with IC(50) values of 2.3 and 7.5 microg/mL, respectively.
Journal ArticleDOI
Absolute configuration, conformation, and chiral properties of flavanone-(3→8″)-flavone biflavonoids from Rheedia acuminata
Xing-Cong Li,Alpana S. Joshi,Bo Tan,Hala N. ElSohly,Larry A. Walker,Jordan K. Zjawiony,Daneel Ferreira +6 more
TL;DR: In this paper, the absolute configurations of three flavanone-(3→8″)-flavone type biflavonoids, (+)-morelloflavone (1), (+)-volkensiflavone-7-sulfate (2 ), isolated from Rheedia acuminata, were confirmed by circular dichroism as 2 R,3 S, hence clarifying the literature confusion of 2 S,3 R absolute configuration for (+-morelloftlavone.
Journal ArticleDOI
Diurnal and Seasonal Effects on the Taxane Content of the Clippings of CertainTaxus Cultivars
TL;DR: The best time to harvest Taxus clippings for the production of taxanes (especially 1 and 6) is approximately one month from the beginning of new growth (flush). The date of harvest could vary depending on the geographic location and weather conditions.
Journal ArticleDOI
Concentrations of taxol and related taxanes in the needles of different Taxus cultivars
Hala N. ElSohly,Edward M. Croom,Wlodzimierz J. Kopycki,Alpana S. Joshi,Mahmoud A. ElSohly,James D. McChesney +5 more
TL;DR: The taxane content of the needles of 57 cultivars obtained from five major nurseries in the United States is presented in this article, and the results of these analyses showed that the total “useful” taxanes varied between 0.0232-0.113%, with 1 and 6 being the most abundant taxanes.

Absolute Configuration, Conformation, and Chiral Properties of Flavanone‐(3→8′′)‐Flavone Biflavonoids from Rheedia acuminata.
