Alkaloid composition of a smile from Taiwan Studies on the alkaloids michelia fuscata blume
Abstract
Michelia (Micheliafuscata BLUME) are Magnolia (Magnoliaceae) Michelia genus (Michelia
) Is a small evergreen shrub. In Michelia is, there are a variety of plants are civil for the anti-cancer; smile, in China
Civil use as anti-inflammatory detoxification. For the detailed tracking of the plant active ingredients and chemical composition of plant classification provided, students
Synthesis and biological activity of research data, some began to build the plant stem base components of skin.
The composition of the plant leaves, have isolated oxoushinsunine (Ⅰ), magnolamine (Ⅲ), magn
oline (Ⅳ), magnocurarine (Ⅴ) and magnoflorine(Ⅵ); this part from the stem bark of this plant
, In addition to (Ⅰ), (Ⅲ), (Ⅳ) of three components, the yet confirmed there anonaine (Ⅱ), michelabine
(Ⅶ), asimilobine (Ⅷ), corypalline (Ⅸ) and N-methylcoclaurine (Ⅹ) the five
Alkaloids exist. One oxoushinsunine (Ⅰ) and anonaine (Ⅱ) have been proven to be toxic cells and
Antibacterial activity.
In addition, the process of alkaloids isolated from the thin layer chromatography, the results suggest there usbinsunine (Ⅸ)
And retieuline (Ⅶ) exist. One ushunsunine (Ⅸ) is considered oxoushinsunine (Ⅰ)
Of precursor substances: reticuline(Ⅶ) and N-methylcoclaurine (Ⅹ) presumably magnolamine (
Ⅲ) are the precursors. Co-existence of several components for more than one plant, the biosynthesis from the biological point of view (biogenet
ic consideration) of view, is very interesting lies.
