The root- bark powder of Croton macrostachys Hochstex. A.rnRich . (Euphorheaceae) ( n nCj') , used in Ethiopia for curingrnspreading wounds, was extraced with diethyl ether . The crudernextract, on fractionation by column chromatography (Silica gel)rnyielded a major solid compound A (mp 210- 212o ) crystallizablernfrom acetone- methanol (9 ; l) into be autiful needle aggregates,rnthe structure of which was identified , using I R, PHR and MSrndata , to be that of lupeol , aknown antitumor agent. Therntumor inhibitor y compound Crotepoxide which was previouslyrnisolated from the fruits could not be detecte in t he rootbarkrnextract. Preliminary investigation also showed thernpresence of trace solids B and C having the same Rf on TLC.rnB was water isoluble white solid while C was water solublernand showed strong blue fluorescence unde r UV- I amp. Thernpresence of quaternary alkaloid was also confirmed in thernroot- bark .
Subsurface Intelligence & Critical Mineral Exploration
Modern Geology projects now focus on Machine Learning in Mineral Targeting, Carbon Capture & Storage (CCS) Geologic Modeling, and Critical Mineral Systems (Lithium, REEs). If your research involves Hydrogeological Connectivity, Seismic Inversion, or Geotechnical Site Characterization, ensure your analysis follows the JORC or NI 43-101 reporting standards and utilizes robust 3D Subsurface Visualization and Geochemical Fingerprinting frameworks.
