A new epoxynaphthoquinol from Rumex japonicus.
A new epoxynaphthoquinol derivative, 3-acetyl-2-methyl-1, 5-dihydroxy-2,3-epoxynaphthoquinol (I), was isolated from the root of Rumex japonicus. The structure was elucidated by high field 1D and 2D NMR techniques.
متن کاملBioactive compounds from Rumex plants
Two new naphthalene acylglucosides, rumexneposides A (1) and B (2), together with 12 known compounds (3-14), were isolated from the roots of Rumex nepalensis. Their structures were established by chemical and spectroscopic methods. The biological activities of compounds 1-14 as well as an additional 11 compounds previously isolated from R. nepalensis and Rumex hastatus (15–25) were evaluated ag...
متن کاملRumex acetosa Y chromosomes: constitutive or facultative heterochromatin?
Condensed Y chromosomes in Rumex acetosa L. root-tip nuclei were studied using 5-azaC treatment and immunohistochemical detection of methylated histones. Although Y chromosomes were decondensed within root meristem in vivo, they became condensed and heteropycnotic in roots cultured in vitro. 5-azacytidine (5-azaC) treatment of cultured roots caused transitional dispersion of their Y chromosome ...
متن کاملIsolation and Identification of Human Renin Inhibitor from Aralia cordata (Udo)
We screened for human renin inhibitory activity in wild vegetables and found the activity in methanol extract of Aralia cordata. Physico-chemical data on the isolated inhibitors were identical to those of (–)-kaur-16-en-19-oic acid (kaurenic acid, KA) and pimaradienoic acids (PDA, 8:2 mixture of pimara-8(14), 15-dien-19-oic acid: pimara-9(11) 15-dien-19-oic acid). KA and PDA also inhibited porc...
متن کاملCloning and characterization of dispersed repetitive DNA derived from microdissected sex chromosomes of Rumex acetosa.
Rumex acetosa is characterized by a multiple chromosome system (2n = 12 + XX for females, and 2n = 12 + XY1Y2 for males), in which sex is determined by the ratio between the number of X chromosomes and autosome sets. For a better understanding of the molecular structure and evolution of plant sex chromosomes, we have generated a sex chromosome specific library of R. acetosa by microdissection. ...
