A new tropane alkaloid and other constituents of Erythroxylum rimosum (Erythroxylaceae)
(2013-05-01)
A new tropane alkaloid, named the 7β-acetoxy-3β,6β- dibenzoyloxytropane (1), was isolated from a methanol extract of Erythroxylum rimosum O.E. Schulz leaves. Other known compounds were detected, including quercetin, ...

Rearranged (4 -> 2)-abeo-clerodane and clerodane diterpenes from Aristolochia chamissonis
(Elsevier B.V., 1999-02-01)
From stems of Aristolochia chamissonis Duch., five new diterpenes, one rearranged (4 --> 2)-abeo-clerodane and four ent-clerodanes, were isolated. Their structures were determined to be (+)-(4 --> 2)-abeo-kolavelool-3-oic ...
HDL-C concentration is related to markers of absorption and of cholesterol synthesis: Study in subjects with low vs. high HDL-C
(ELSEVIER SCIENCE BV, 2011)
Background: The antiatherogenic functions of high density lipoprotein (HDL-C) include its role in reverse cholesterol transport, but to what extent the concentration of HDL-C interferes with the whole-body cholesterol ...
