7. Bioactivity in plants: the link between phytochemistry and medicine
TL;DR: The development of medicinal plant research over the last 30 years is reviewed with reference to the search for new active principles, and difficulties inherent to activity guided isolation and the specific requirements of bioassays are discussed.
Journal ArticleDOI
Natural product isolation
TL;DR: This updated review deals with sample preparation and purification, recent extraction techniques used for natural product separation, liquid-solid and liquid-liquid isolation techniques, as well as multi-step chromatographic operations.
Journal ArticleDOI
Chemistry, Biogenesis, and Biological Activities of Cinnamomum zeylanicum
TL;DR: The present review provides a coherent presentation of scattered literature on the chemistry, biogenesis, and biological activities of cinnamon to exhibit antioxidant, antimicrobial, and antidiabetic activities.
Journal ArticleDOI
Loose nanofiltration membrane custom-tailored for resource recovery
TL;DR: In this paper, a review summarizes the development of the nanofiltration (NF) membranes, focusing on their preparations and applications, and offers guidance to improve the membrane separation performance, especially for the resource recovery.

Droplet countercurrent chromatography
T Tanimura,Yoichiro Ito +1 more
TL;DR: Milligram quantities of dinitrophenyl (DNP) amino acids were separated with an efficiency comparable to that of gas chromatography.
Journal ArticleDOI
Lignans of Forsythia intermedia
TL;DR: The 1 H NOE difference spectra recorded for phillygenin and epipinoresinol necessitate the reversal of earlier chemical shift assignments for axial and equatorial protons on C-9 of furofuran lignans having one axialand one equatorial aryl group (the epi series).

Journal ArticleDOI
Antimicrobial flavonoids from Psiadia trinervia and their methylated and acetylated derivatives
TL;DR: From a dichloromethane extract and a hydrolysed methanolic extract from the leaves of Psiadia trinervia, 13 3-methylated flavonols have been isolated as discussed by the authors.

A new centrifugal counter-current chromatograph and its application
Wataru Murayama,Kobayashi Tetsuya,Yasutaka Kosuge,Hideki Yano,Yoshiaki Nunogaki,Kan-Ichi Nunogaki +5 more
TL;DR: In this paper, a centrifugal counter-current chromatograph with a rotary seal joint has been developed for separations of a set of dinitrophenyl amino acids and application examples of the method to the separation of some biological materials are presented.
