Abstract The three major curcuminoids, curcumin, demethoxycurcumin and bis‐demethoxycurcumin, from Curcuma domestica Val. ( longa L.) xanthorrhiza Roxb. (Zingiberaceae) were fully separated quantified in less than 5 min using a capillary zone electrophoresis method with standard fused‐silica capillaries photodiode array detection. An electrolyte solution of 20 m phosphate, 50 sodium hydroxide 14 β ‐cyclodextrin was found to be appropriate. Quantification performed 3,4‐dimethoxy‐ trans...
Extracts from saffron, the dried stigmata Crocus sativus L., are being used more and in preclinical clinical trials for treatment of cancer depression. Because known quality problems HPLC methods on RP18 2.5 μm monolithic material have been developed validated control including quantification crocins 1 to 5, crocetin, picrocrocin degradation products, cis-crocins. Additionally, a GC-MS method has allowed detection volatile compounds pentane extract saffron. Both systems together...
Ten compounds, harpagoside (1), 8-p-coumaroylharpagide (2), 8-feruloylharpagide (3), 8-cinnamoylmyoporoside (4), pagoside (5), acteoside (6), isoacteoside (7), 6′-O-acetylacteoside (8), cinnamic acid (9) and caffeic (10) were isolated from the storage roots of Harpagophytum procumbens, Pedaliaceae. Compounds 1, 2, 6, 7 9 are known for H. procumbens; 3 10 first time compounds 4, 5 8 new natural products. Their structures elucidated using spectroscopic data (NMR, with NOE, COSY HMBC...
Bilberries (Vaccinium myrtillus) are used to treat non-specific diarrhea and for symptoms related varicose veins. Because they quite expensive fruits, quality problems compositional fraud might occur dietary supplements. This study investigated fresh/dried bilberries supplements by high-performance liquid chromatography (HPLC) fingerprinting against a quantified bilberry reference extract identity testing test total anthocyanin content HPLC quantification of hydrolyzable condensed tannins....
The above-ground plant material from Passiflora incarnata is used for relief of symptoms mental stress and to aid sleep. In Europe, passion flower products are marketed either as registered herbal medicinal or food supplements. Passion sleep disorders increasingly recommended patients by physicians social advertisement, but the potential consumers in most cases not able differentiate between supplements licensed products. Analytical investigations validated protocols on different sources was...
Water-soluble high molecular weight compounds were isolated in yields of 21–22% from the oleogum Boswellia serrata and B. carteri. Using anion exchange chromatography gel permeation chromatography, different proteoglycans purified characterized, leading to four principally groups: (i) Hyp-/Ser-rich extensins with O-glycosidic attached arabinan side chains; (ii) Modified extensins, arabinogalactosylated chains containing GlA 4-O-Me-GlcA; (iii) Glycoproteins N-glycosidic higher amounts Fuc,...
Within a systematic phytochemical investigation of the leaves Rhododendron ferrugineum L. (Ericaceae), volatile oil was isolated (0.7 %) and its constituents were characterized. Eleven flavonoids characterized, with quercetin 3-O-[6′′-O-(2-methyl-1-oxobutyl)]-β-D-glucopyranoside 2R,3R-dihydromyricetin 3-O-β-L-arabinopyranoside as new natural products. Beside monomeric flavan-3-ols (catechin, epicatechin, gallocatechin, epigallocatechin) from tannin fraction (about 3.5 % calculated...
