Antiplasmodial Activity and Phytochemical Constituents of Selected Antimalarial Plants Used by Native People in West Timor Indonesia.

Objectives: To document traditional antimalarial plants used by Tetun ethnic people in West Timor Indonesia and evaluate the antiplasmodial activity and phytochemicals of several plants that are widely used as oral medicine.

Materials And Methods: A field study to document antimalarial plants followed by laboratory works to test antiplasmodial activity and identify the phytochemical constituents of some selected plants extract were applied. The inhibitory potency of ethanolic extracts of wood, roots of , , and , whole plant of and , stem barks of , , and , and leaves of on the 3D7 strain were tested.

Metabolite Profiles in Various Plant Organs of Justicia gendarussa Burm.f. and Its in Vitro Cultures.

Metabolite profiles of plant organs and their in vitro cultures of have been studied by using Ultra Performance Liquid Chromatography-Quadrupole Time-of-Flight-Mass Spectrometry (UPLC-Qtof-MS). Samples of leaves, stems, roots, and shoot cultures showed similar patterns of metabolites, while samples of root cultures gave very different profiles. Concentrations of secondary metabolites in shoot cultures were relatively low compared to those in the leaves and roots of the plants.

Metabolite Profiling of Justicia gendarussa Burm. f. Leaves Using UPLC-UHR-QTOF-MS.

An ultra-performance liquid chromatography ultra-high-resolution quadrupole-time-of-flight-mass spectrometry (UPLC-UHR-QTOF-MS) metabolite profiling ofxs Justicia gendarussa Burm. f. leaves was performed.
