Methanolic extracts of diff erent parts of fi ve medicinal plants, Ferula assafoetida L. resin, Grewia asiatica L. leaves, Ipomoea hederacea Jacq. seeds, Lepidium sativum L. seeds and Terminalia chebula Retz. fruits were tested in vitro for their cytotoxic, phytotoxic, insecticidal, nematicidal and anthelmintic activities. Ipomoea hederacea showed very signifi cant phytotoxic and cytotoxic acti...
Garden cress or "hab arachad" seeds are considered one of the popular medicinal herbs used in Arabian countries. Garden cress meal (Lepidium sativum) is a by-product remaining after the extraction of the oil from seeds. The decline in male reproductive health and fertility in the last 30 years has been linked to environmental toxicants. The present study was designed to investigate the effects ...
Selective foraging by granivores can have important consequences for the structure and composition of plant communities, and potentially severe consequences for rare plant species. To understand how granivore foraging behavior affects common and rare plant species, diet selection should be viewed relative to the availability of alternative seed options, and with consideration of the individual ...
Seven new rare sinapoyl acylated flavonoid glycosides, apetalumosides A1 (1), B8 (2), B9 (3), B10 (4), B11 (5), B12 (6), and C1 (7) were isolated from the seeds of Lepidium apetalum Willd. Their structures were elucidated by chemical and spectroscopic methods.
The present investigation has been carried out to determine the proximate composition, amino acids, metal contents, oil composition as well as the antioxidant capacity of the seeds of Ipomoea hederacea Jacq. and Lepidium sativum L. Proximate composition indicated a great difference in oil (14.09 ± 0.66, 28.03 ± 1.05) and fibre (16.55 ± 0.31, 6.75 ± 1.20) contents for I. hederacea and L. sativum...
Three new compounds, apetalumosides C₁ (1), D (2), and 1-thio--d-glucopyranosyl(1→1)-1-thio-α-d-glucopyranoside (3), together with twenty-two known ones (4-25) were obtained from the seeds of Lepidium apetalum Willd. Among the known isolates, 5-8, 10-13, 16-20, and 25 were obtained from the genus for the first time; 4, 14, 15, and 21-24 were isolated from the species for the first time. Meanwhi...
A major challenge in basic research into homeopathic potentisation is to develop bioassays that yield consistent results. We evaluated the potential of a seedling-biocrystallisation method. Cress seeds (Lepidium sativum L.) germinated and grew for 4 days in vitro in Stannum metallicum 30x or water 30x in blinded and randomized assignment. 15 experiments were performed at two laboratories. CuCl...
The chemical composition of the essential oils of S. hierosolymitana Boiss. and S. multicaulis Vahl. var. simplicifolia Boiss. collected in Lebanon was studied by means of GC and GC-MS analysis. In all 115 compounds were identified: 82 for S hierosolymitana and 72 for S. multicaulis var. simplicifolia. The presence of carbonylic compounds (17%) characterizes the oil from S. hierosolymitana,whil...
Lepidium draba (Brassicaceae) is a major concern for agriculture and biodiversity in the western United States. As current control methods do not provide long-term, sustainable solutions, research has been conducted to find biological control agents. Ceutorhynchus assimilis is one of the currently investigated candidates. Known as oligophagous in the literature, a specialist clade of this root-...
