TL;DR: Experiences from the mass bioprospecting efforts undertaken by the United States National Cancer Institute, the National Cooperative Drug Discovery Groups (NCDDG) and the International Cooperative Biodiversity Groups (ICBG) programs demonstrate that mass biopsying is a complex process, involving expertise from diverse areas of human endeavors, but central to it is the Memorandum of Agreement (MOA) that recognizes issues on genetic access, prior informed consent, intellectual property and the sharing of benefits that may arise

TL;DR: Bioassay-directed fractionation of the dried roots of Asparagus cochinchinensis led to the isolation of a new spirostanol saponin, asparacoside, which demonstrated moderate cytotoxicities in a panel comprised of KB, Col-2, LNCaP, Lu-1, and HUVEC cells.

TL;DR: A field survey of commonly used medicinal plants in the district of Paksan in the Lao People's Democratic Republic indicates that 55 species of plants, belonging to 49 genera in 31 families of vascular plants, are used in day-to-day medical therapy.

TL;DR: Whether plants with ethnomedical uses from Vietnam and Laos have a higher hit rate in bioassay testing than plants collected from a national park in Vietnam with the goal of maximizing taxonomic diversity (“random” collection) is analyzed.

TL;DR: Bioassay‐guided fractionation of the antimalarial‐active CHCl3 extract of the dried stem of Nauclea orientalis has resulted in the isolation of two novel tetrahydro‐β‐carboline monoterpene alkaloid glucosides.
