The lotus leaf extract is the dry leaf extract of the water lily plant Nelumbonucifera Gaertn.
, and mainly contains alkaloids, flavonoids, volatile oils and other components
.
Flavonoids are the scavengers of most oxygen free radicals, have significant effects on the treatment of coronary heart disease, hypertension and other diseases, and have antibacterial and anti-inflammatory effects; they can be used as raw materials for cardiovascular diseases, and can also be widely used in functional Food, health food, beverages, food preservatives and cosmetics
.
The source plant is the dried leaves of Nelumbonucifera Gaertn.
, a water lily plant
.
Produced in most parts of the country
.
[Plant form] It is semicircular or folded fan-shaped, and after unfolding, it is sub-circular, with entire or slightly wavy edges
.
The upper surface is dark green or yellowish green, relatively rough; the lower surface is light gray-brown, relatively smooth, with 21 to 22 thick veins, projecting from the center to the periphery; the center has a protruding petiole residue
.
Brittle and easily broken
.
Slightly clear aroma, slightly bitter taste
.
Chemical composition of lotus leaf extract: 1.
Alkaloids Three monomer components, nuciferine, roemerine and O-nornuciferine, were isolated from lotus leaf in the early stage.
, Now many alkaloid compounds have been isolated from lotus leaves
.
The lotus leaf alkaloids can be divided into the following three categories according to the structure of the parent nucleus
.
Monobenzyl isoquinolines: including armepa-vine, N-methylisococlaur-ine, N-methylcoclaurine (N-methylcoclaurine)
.
Apophines: including N-nornuciferine, O-nornuciferine, anonaine, roemerine, tulipine Base (lirioderine), N-norarmepavine (N-norarmepavine), 2-carboxy-1-methoxyaporphine (2-hydroxy-I-methoxyaporphine)
.
Dehydroaporphines: dehydronuciferine, dehydChemicalbookroroemerine
.
2.
Flavonoids There are 16 flavonoids isolated from lotus leaves, most of which are quercetin as the nucleus, sugar chains include glucose, xylose, galactose, rhamnose, etc.
, and also naphthalene and myricetin derivatives
.
3.
Organic acids tartaric acid, citric acid, malic acid, oxalic acid, gluconic acid, aberacid,
etc.
4.
Volatile oils cis-3-hexenol and trans-2-pentenol, 1-penten-3-ol, trans-2-hexenal and the like
.
5.
Other ingredients also contain β-sitosterol, carotene, organic acids, β-sitosterol-3-O-β-D-glucopyranoside, isophytol, trans-phytol, 7, 11, 15-trimethyl-2-hexadecanone, 10 -eicosanol, 24(R)-ethylcholest-6-ene-5α-ol-3-O-β-D-glucopyranoside, lotus leaf polysaccharides, fatty acids, proteins and trace elements
