Induction of bulb maturity of Ornithogalum thyrsoides
The influence of bulb maturity at bulb harvest on growth and flowering response of Ornithogalum thyrsoides Jacq. ‘Chesapeake Starlight’ was investigated. Experiments were designed to determine if bulb maturity can be induced by bulb storage temperatures and whether bulb maturity can be evaluated by flowering responses. Bulbs with all senesced leaves at harvest were considered ‘‘mature’’ or with...
متن کاملSynthetic cardenolides and related products.
ABSTRACT Since the publication in 1785 of one of the great classics of clinical medicine, 'An Account of the Foxglove and Some of its Medical Uses' by William Withering', the steroidal glycosides of digitalis have maintained a unique position among drugs. Their usefulness as life saving products is unchallenged and yet very few drugs are known to possess a narrower margin of safety. Their toxic...
متن کاملNew cardenolides from the seeds of Adonis aestivalis.
Chemical investigation of the seeds of Adonis aestivalis has led to the isolation of a new cardenolide (3β,5α,14β,17β-tetrahydroxycard-20,22-enolide) (1), two new glycosides (2, 3) of 1, and a new strophanthidin hexaglycoside (4), together with a known compound, strophanthidin 3-O-β-D-glucopyranoside (5). The structures of 1-4 were determined by 1D- and 2D-NMR spectroscopic analysis and the res...
متن کاملAntiproliferative activity of cardenolides isolated from Streptocaulon juventas.
Sixteen cardenolides, two hemiterpenoids, two phenylpropanoids and a phenylethanoid isolated from the roots of Streptocaulon juventas (LOUR.) MERR. were examined for their antiproliferative activity toward three human-derived (HT-1080 fibrosarcoma, lung A549 adenocarcinoma, cervix HeLa adenocarcinoma) and three murine-derived (colon 26-L5 carcinoma, Lewis lung carcinoma, B16-BL6 melanoma) cell ...
متن کاملResurrection of Ornithogalum brevipedicellatum (Asparagaceae) with morphological and molecular data
This study evaluates Ornithogalum brevipedicellatum, which was previously accepted as a synonym of O. oligophyllum, as a separate distinct species and discusses the similarities and differences between O. brevipedicellatum and its related species (O. oligophyllum and O. pamphylicum). Similarities and differences among these species were identifi ed by morphological and molecular studies. The le...
