Development of high-performance liquid chromatographic for quality and authenticity control of Chinese propolis.[Pubmed:24894633]
J Food Sci. 2014 Jul;79(7):C1315-22.
A RP-high-performance liquid chromatography (HPLC) method was developed for quality control of Chinese propolis by simultaneous analysis of 12 flavonoids and 8 phenolic acids. The results showed that vanillic acid, rutin, myricetin, and luteolin were not detected in all of the analyzed propolis and poplar tree gum samples. The caffeic acid, ferulic acid and p-coumaric acid were not detected in poplar tree gum but were detected in propolis, which suggest that they are practical indexes of distinguishing propolis from poplar tree gum. The flavonoid profiles of poplar tree gum were found to be similar to those of propolis, which are dominated by pinobanksin, pinocembrin, 3-O-Acetylpinobanksin, chrysin, and galangin. Therefore, the proposed method could be applied to exclude poplar tree gum from propolis with cafferic acid, ferulic acid, and p-coumaric acid as qualitative markers, and distinguish poplar source resin from other illegal substances, and evaluate the quality grading of poplar-type propolis with pinobanksin, pinocembrin, 3-O-Acetylpinobanksin, chrysin, and galangin as qualitative and quantitative markers.
A new flavonone from seeds of Alpinia katsumadai and its neuroprotective effect on PC12 cells.[Pubmed:25272494]
Zhongguo Zhong Yao Za Zhi. 2014 Jul;39(14):2674-8.
A new flavonone, named as (2R, 3S)-pinobanksin-3-cinnamate(1), together with six known compounds, pinocem-brin (2), pinobanksin (3), 3-O-Acetylpinobanksin (4), galangin (5), kumatakenin(6), and 3-methylkaempferol (7), were isolated from a 95% ethanol extract of seeds of Alpinia katsumadai through a combination of various chromatographic techniques, including silica gel and Sephadex LH-20. The structure of compound 1 was elucidated by spectroscopic data analysis. Compound 1 exhibits a potent neuroprotective effect against the corticosterone-damaged PC12 cells, which may be underlying the effect by scavenging intracellular ROS.
Negative ion 'chip-based' nanospray tandem mass spectrometry for the analysis of flavonoids in glandular trichomes of Lychnophora ericoides Mart. (Asteraceae).[Pubmed:18980260]
Rapid Commun Mass Spectrom. 2008 Dec;22(23):3802-8.
This paper reports a method for the analysis of secondary metabolites stored in glandular trichomes, employing negative ion 'chip-based' nanospray tandem mass spectrometry. The analyses of glandular trichomes from Lychnophora ericoides, a plant endemic to the Brazilian 'cerrado' and used in traditional medicine as an anti-inflammatory and analgesic agent, led to the identification of five flavonoids (chrysin, pinocembrin, pinostrobin, pinobanksin and 3-O-Acetylpinobanksin) by direct infusion of the extracts of glandular trichomes into the nanospray ionisation source. All the flavonoids have no oxidation at ring B, which resulted in a modification of the fragmentation pathways compared with that of the oxidised 3,4-dihydroflavonoids already described in the literature. The absence of the anti-inflammatory and antioxidant di-C-glucosylflavone vicenin-2, or any other flavonoid glycosides, in the glandular trichomes was also demonstrated. The use of the 'chip-based' nanospray QqTOF apparatus is a new fast and useful tool for the identification of secondary metabolites stored in the glandular trichomes, which can be useful for chemotaxonomic studies based on metabolites from glandular trichomes.
