A luminescence assay for natural product inhibitors of the Mycobacterium tuberculosis proteasome
ConclusionsLuminescence is the more suitable assay for assay of plant natural product extracts. The sensitivities of the luminescence and fluorescence assays are comparable. A Z′‐factor of 0.58 for the luminescence assay makes it suitable for medium‐to‐high throughput screening efforts. Copyright © 2016 John Wiley & Sons, Ltd. (Source: Phytochemical Analysis)

Flavonoids from the flowers of Impatiens glandulifera Royle isolated by high performance countercurrent chromatography
ConclusionThis is the first report on the flavonoid composition of the species Impatiens glandulifera. The developed protocol was successfully used to isolate the main flavonoids from the crude extract of IGFs. This combined HPCCC and HPLC procedure could be applied to the fast fractionation and recovery of flavonoid derivatives of other plant extracts. Copyright © 2016 John Wiley & Sons, Ltd.

Analysis of phytochemical variations in dioecious Tinospora cordifolia stems using HPLC/QTOF MS/MS and UPLC/QqQLIT‐MS/MS
ConclusionsPhytochemicals in the stem of male and female Tinospora cordifolia showed significant qualitative and quantitative variations. LC‐MS and MS/MS methods can be used to differentiate between male and female plants based on their chemical profiles and quantities of the marker bioactive alkaloids. This chemical composition difference was also evident during vegetative stage when there were no male and female flowers. Copyright © 2015 John Wiley & Sons, Ltd. (Source: Phytochemical Analysis)
