THE TITLE COMPOUND (SYSTEMATIC NAME 1,2,3,10,11,12-hexa-meth-oxy-6,7-dimethyl-5,6,7,8-tetra-hydro-dibenzo[a,c]cyclo-oc-ten-6-ol), C(24)H(32)O(7), has a dibenzocyclo-octa-diene skeleton. There are three mol-ecules in the asymmetric unit, which are related by a pseudo-translation in the direction of the c axis. Nevertheless, the three mol-ecules differ in the torsion angle of one of the meth-oxy ...

Abstract Repeated column chromatography using Sephadex LH-20, silica gel (SiO 2 ), and octadecyl SiO (ODS) as well preparative HPLC led to isolation of a new dibenzocyclooctadiene lignan along with four known ones, gomisin L2 ( 1 L1 M1 3 M2 4 ). Their chemical structures were fixed based on MS, IR, NMR data analyses. In addition, the stereochemistry atropisomers, absolute configuration axial ch...

There are some reports on the lignan constituents of Linum spp. In this study, we investigated the cyototoxicity of Linum spp. in vitro cultures for the first time. If they show significant cytotoxic activity, they will be valuable candidates for isolation of cytotoxic compounds in large scale from them by tissue culture technology. In our study, we chose normal root, hairy root and calli cultu...

Objective The aim of this study is to evaluate the relationship between phytoestrogen intake with endometriosis risk. MaterialsAndMethods A case-control study was conducted on 78 women with a laparoscopically confirmed diagnosis of endometriosis and on 78 normal pelvis women (as the control group). Common dietary intake was collected by a validated 147-item semi-quantitative FFQ. Calculation ty...

The role of microRNAs (miRNAs) during cotton fiber development remains unclear. Here, a total of 54 miRNAs belonging to 39 families were selected to characterize miRNA regulatory mechanism in eight different fiber development stages in upland cotton cv BM-1. Among 54 miRNAs, 18 miRNAs were involved in cotton fiber initiation and eight miRNAs were related to fiber elongation and secondary wall b...
