Suggest a correction!Properties relevant to use:
Crinum stuhlmannii (Baker) is a perennial herb whose bulbs and leaves have been examined for their alkaloid composition. Phytochemical studies have documented the presence of a suite of amaryllidaceae‑type alkaloids, notably lycorine, crinine and related nor‑ and O‑acetyl derivatives. These compounds are stable under acidic conditions, exhibit characteristic UV absorbance near 290 nm, and possess molecular weights that facilitate detection by HPLC‑UV and LC‑MS. Laboratory extracts are prepared as dry powders or as purified isolates and are employed as reference standards in chromatographic method validation and in the study of alkaloid biosynthetic pathways across the Amaryllidaceae. The plant’s relatively high alkaloid yield (reported in the range of 0.3–0.8 % dry weight in bulbs) makes it a practical source for analytical standards without the need for extensive fractionation.
Standards and regulation:
Alkaloid extracts intended for use as certified reference materials are produced in accordance with ISO 17034 (general requirements for reference material producers) and are supplied with documented uncertainty measurements. Analytical laboratories that employ these standards follow ISO/IEC 17025 (general requirements for the competence of testing and calibration laboratories) to ensure data traceability and method validation. When the extracts are used in the European Union for research purposes, the relevant REACH regulation (EC No 1907/2006) applies to the handling of chemical substances, although no specific occupational exposure limits have been established for Crinum‑derived alkaloids.
Sustainability and sourcing:
Crinum stuhlmannii occurs naturally along the East African coast and is presently not listed in the CITES appendices. Wild populations are scattered and generally limited, prompting research programs to source material from ex situ cultivated plants to reduce pressure on natural habitats. Propagation by seed or bulb division is feasible under controlled greenhouse conditions, and sustainable harvesting protocols—such as removing only a fraction of the bulb biomass—have been recommended in regional conservation guidelines. Documentation of provenance and cultivation history is increasingly required by funding agencies to demonstrate compliance with biodiversity conservation policies.
