Constituents and Phytochemicals of Dodder Seed.:
Main Content and Phytochemicals:kaempferol (C15H10O6),(0.198%); quercetin (C15H10O7),(0.119~0.204%); astragalin (C21H20O11),etc.
Nutritions:Chemical constituents in Semen Cuscutae include biological alkaloids, anthraquinone, coumarin, flavones, glycoside sterols, terpene, tannic acid and others. Compounds that contain flavones include quercetin, astragalin, and hyperin, with the total flavone amount being approximately 3.0% in the raw herb. Compounds that include sterols include: cholesterol, campesterol, beta-sitosterol, stigmasterol and beta-amyrin.The amino acid content is approximately 0.076%, and the total polysaccharide content is 8.5%-9.2% in the raw herb.Microelements identified so far in this herb are calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), and copper (Cu).
Other Phytochemicals: neosesamin; kaempferol-3-O-Beta-D-glucopyranoside; palmitic acid; stearic acid; daucosterol; cuscutic acid A1; cuscutic acid A2;cuscutic acid A3 (cuscutic acids A1,A2,A3); hyperoside; quercetin-3-O-beta-galactoside-7-O-beta-gluoside; campesterol; beta-sitosterol; stigmasterol; beta-carotene;beta-amyrin; lutein; taraxanthin;etc.
The active constituents in Dodder seed are thought to be a group of flavonoids.The seed is rich in quercetin and also contains cuscutin, astragalin, vitamin A, hyperosides and sterols.
Chemical constituents in Semen Cuscutae include biological alkaloids, anthraquinone, coumarin, flavones, glycoside sterols, terpene, tannic acid and others. Compounds that contain flavones include quercetin, astragalin, and hyperin, with the total flavone amount being approximately 3.0% in the raw herb. Compounds that include sterols include: cholesterol, campesterol, beta-sitosterol, stigmasterol and beta-amyrin. The amino acid content is approximately 0.076%, and the total polysaccharide content is 8.5%-9.2% in the raw herb 4,6. Microelements identified so far in this herb are calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), and copper (Cu).
Quantitative analysis of Semen cuscutae:the quantitative analysis of the total flavone in 7 species revealed the contents: Cuscuta Chinensis (3.0%), Cuscuta Australis (3.2%) as compared with Cuscuta Europaea (4.5%). Cuscuta Chinensis has the highest content of polysaccharide of about 5-6%. The experimental results provide a scientific basis the rational use of Cuscuta .
Recent Study the chemical constituents of the seeds of Cuscuta chinensis,Method: Separation was carried out by polyamide and silica gel chromatography,the compounds were identified by means of physico-chemical and spectroscopic methods. Results: Eight compounds were isolated from the plant and identified as quercetin 3-O-beta-D-galactoside-7-O-beta-D-glucoside (I), quercetin 3-O-beta-D-apiofuranosyl-(1-->2)-beta-D-galactoside (II), hyperoside (III), isorhamnetin (IV), kaempferol (V), quercetin (VI), d-sesamin (VII) and 9(R)-hydroxy-d-sesamin (VIII). Conclusion: Compounds IV and VII were isolated from Cuscuta for the first time, and I, II and VIII were characteristic constituents for this vegetable drug.
