ABSTRACT
The species of the Solidago are abundant and possess great value in medicine. Many relevant researches of chemical constituents and bioactivities from the genus Solidago have been further reported by many scientists. The review is to present an overview about studies on chemical constituents and bioactivities of the Solidago since 2011, which will provide some foundations and references for the later study.
ABSTRACT
<p><b>AIM</b>To separate and identify the chemical constituents of the aril of Torreya grandis cv. Merrilli.</p><p><b>METHODS</b>Three lignins were isolated by chromatography and their chemical structures were elucidated by IR, EI-MS, 1HNMR, 13CNMR, DEPT and 2D-NMR spectral methods.</p><p><b>RESULTS</b>Three lignins were identified as pinonesinol, dihydrodehydrodiconiferylalcohol and (7,8-cis-8,8'-trans)-2',4'dihydroxyl-3, 5-dimethoxy-lariciresinol.</p><p><b>CONCLUSION</b>These compounds were isolated from this plant for the first time, and compound III is a new compound.</p>

<p><b>AIM</b>To study the bioactive constituents from Anthopleura pacifica.</p><p><b>METHODS</b>Compounds were separated by Pyricularia oryzae bioassay-guided fractionation method with a combination of multi-chromatography. Their chemical structures were determined on the basis of spectral analysis and chemical evidence.</p><p><b>RESULTS</b>A portion showing activity against P. oryzae was obtained and from the portion four compounds were identified as N-hydroxyethyl-N-tetradecanoyl-(2S,3R)-octadecasphinga-4(E), 8(E)-dienine (a), N-hydroxyethyl-N-(9Z-hexadecenoyl)-(2S,3R)-octadecasphinga-4 (E), 8 (E)-dienine (b), N-hydroxyethyl-N-hexadecanoyl-(2S,3R)-octadecasphinga-4(E), 8 (E)-dienine (c) and N-hydroxyethyl-N-(13Z-docosenoyl-(2S,3R)-octadecasphinga-4(E), 8(E)-dienine(d).</p><p><b>CONCLUSION</b>All the four compounds are new ceramides.</p>
