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. Lannotinidine H (1) is the first Lycopodium alkaloid possessing a lycopodane skeleton with an additional C...
متن کاملThe Genus Diphasiastrum and Its Lycopodium Alkaloids.
The genus Diphasiastrum includes at least 23 species distributed primarily across the northern temperate and subarctic areas of the world. These plants produce an array of lycopodium alkaloids, and some species such as Diphasiastrum complanatum have been used in traditional medicine for ages for various conditions. Hybridization is common in this group of plants and they have always been a chal...

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...
