1.[Study on chemical constituents from ethyl acetate extract of Myricaria bracteata].
Zhang Y;Yuan Y;Cui B;Li S Zhongguo Zhong Yao Za Zhi. 2011 Apr;36(8):1019-23.
OBJECTIVE: ;To study the chemical constituents from the ethyl acetate extract of Myricaria bracteata.;METHOD: ;The chemical constituents were isolated and purified by chromatographic techniques, and their structures were identified by physical characters and spectroscopic analysis.;RESULT: ;Sixteen compounds were isolated from the ethyl acetate portion of the 95% ethanolic extract of Myricaria bracteata, and identified as myricarin (1), myricarin B (2), 3alpha-hydroxytaraxer-14-en-28-oic acid (3), myricadiol (4), trans-ferulic acid 22-hydroxydocosanoic acid ester (5), docosyl-3, 4-dihydroxy-trans-cinnamate (6), dillenetin (7), 3, 5, 4'-trihydroxy-7-methoxyflavone (8), 3, 5, 4'-trihydroxy-7, 3'-dimethoxyflavone (9), methyl 3, 5-dihydroxy-4-methoxybenzoate (10), 3-hydroxy-4-methoxy cinnamic acid (11), sinapaldehyde (12), vanillin (13), syringaldehyde (14), 3, 3', 4'-trimethoxyellagic acid (15), methyl p-hyroxybenzoate (16).;CONCLUSION: ;Compounds 5, 6, 12-16 were isolated from the genus Myricaria for the fist time, all of the compounds were isolated from this plant for the fist time, except for 8 and 9.
2.RNAi down-regulation of cinnamate-4-hydroxylase increases artemisinin biosynthesis in Artemisia annua.
Kumar R;Vashisth D;Misra A;Akhtar MQ;Jalil SU;Shanker K;Gupta MM;Rout PK;Gupta AK;Shasany AK Sci Rep. 2016 May 25;6:26458. doi: 10.1038/srep26458.
Cinnamate-4-hydroxylase (C4H) converts trans-cinnamic acid (CA) to p-coumaric acid (COA) in the phenylpropanoid/lignin biosynthesis pathway. Earlier we reported increased expression of AaCYP71AV1 (an important gene of artemisinin biosynthesis pathway) caused by CA treatment in Artemisia annua. Hence, AaC4H gene was identified, cloned, characterized and silenced in A. annua with the assumption that the elevated internal CA due to knock down may increase the artemisinin yield. Accumulation of trans-cinnamic acid in the plant due to AaC4H knockdown was accompanied with the reduction of p-coumaric acid, total phenolics, anthocyanin, cinnamate-4-hydroxylase (C4H) and phenylalanine ammonia lyase (PAL) activities but increase in salicylic acid (SA) and artemisinin. Interestingly, feeding trans-cinnamic acid to the RNAi line increased the level of artemisinin along with benzoic (BA) and SA with no effect on the downstream metabolites p-coumaric acid, coniferylaldehyde and sinapaldehyde, whereas p-coumaric acid feeding increased the content of downstream coniferylaldehyde and sinapaldehyde with no effect on BA, SA, trans-cinnamic acid or artemisinin. SA is reported earlier to be inducing the artemisinin yield.
3.[Simultaneous analysis of aromatic aldehydes and coumarins with high pressure liquid chromatography. Application to wines and brandies stored in oak barrels].
Salagoity-Auguste MH;Tricard C;Sudraud P J Chromatogr. 1987 Apr 17;392:379-87.
Aromatic aldehydes (vanillin, syringaldehyde, coniferaldehyde and sinapaldehyde) and coumarins (esculetin, umbelliferone, scopoletin and methylumbelliferone) are natural wood compounds. Storage of wines and brandies in oak barrels increases notably aldehydes and coumarins (particularly scopoletin) concentrations. These compounds were separated by high-performance liquid chromatography, on hydrocarbon bonded reversed-phase packings, with a water-acetonitrile elution gradient. They were first extracted from wines and brandies by diethyl ether and then injected on chromatographic column. A double detection was used to determine simultaneously aromatic aldehydes and coumarins by UV absorption and fluorescence respectively.
