Lannotinidines H-J, new Lycopodium alkaloids from Lycopodium annotinum.
Three new Lycopodium alkaloids, lannotinidines H-J (1-3), were isolated from the club moss Lycopodium annotinum. The structures and relative stereochemistry of 1-3 were elucidated on the basis of spectroscopic data and the absolute stereochemistry of 2 was assigned by chemical correlation.

متن کاملGrowth Response of Seedlings of Zea Mays (L.) to Aqueous Extract of Lycopodium Clavatum (L.)
Natural selection is a phenomenon, which allows nature to select at any point in time the structure and number of organism living in a particular habitat [1]. This competitive tendency has been shown and reported by several authors Bonner [2], Grummer et al. [3], Evenari (1961), Whittaker [4], Putman and Duke [5], and Fischer et al. [6]. Allelopathic behaviour can best be described as direct or...

متن کاملProtective potentials of a plant extract (Lycopodium clavatum) on mice chronically fed hepato-carcinogens.
Chronic feeding of carcinogens p-dimethylamino azobenzene (initiator) and phenobarbital (promoter) for 90 and 120 days elevated activities of acid and alkaline phosphatases, levels of blood glucose and cortisol and decreased the activities of glutathione reductase, succinate dehydrogenase, and blood cholesterol and hemoglobin contents, and levels of serum estradiol and testosterone in mice. Lev...
