TL;DR: The bioassay-guided chemical examination of the rhizomes of R. emodi resulted in the isolation of two new oxanthrone esters and a new anthraquinone ether revandchinone-4, establishing new structures based on spectroscopic and degradative evidence.
83 citations
TL;DR: A pyrrolidine alkamide, Isopiperolein B, has been isolated from the berries of Piper nigrum and its structure was established as 1-[(E)-10-(3,4-methylenedioxyphenyl)-dec-9-enoyl]pyrrolidine based on degradative and spectroscopic evidence.
27 citations
TL;DR: Two new oxanthrone esters have been isolated from the aerial parts of Cassia kleinii based on degradative and spectroscopic evidence and established as 1,8-dihydroxy-3-methyl-6-methoxy-9(10H)-anthracenone-10-oxydecanoate 1 and 2 respectively.
16 citations
TL;DR: From the roots of Cassia kleinii two new oxanthrone esters have been isolated and their structures were established as 1,8-dihydroxy-3-methyl-9(10H)-anthracenone-10-oxyhexadecanoate 3 and 2,6,7-trihydroxy-1,8

TL;DR: Although PSM may negatively affect nutrient utilization, there is evidence that methanogenesis could be suppressed without adversely affecting rumen fermentation, which could be exploited to mitigate methane emission in ruminants.
407 citations
TL;DR: Some candidates, in particular Rheum nobile and Carduus pycnocephalus , consistently decreased methane production without adversely affecting other parameters of the rumen fermentation.

TL;DR: In this paper, the authors give an overview of literature on isolated and characterized anthraquinones from various Cassia species and their repoted applications, which are used in cosmetics and pharmaceuticals.
Abstract: Cassia Linn. (Family Caesalpiniaceae) is a large tropical genus with about 600 species of herbs, shrubs and trees. Most of the plants of the genus are wellknown in Indian system of medicine for their cathartic, purgative and antibiotic properties. Many compounds of structural significance and medicinal importance have been reported from different species of this genus. Species of Cassia are rich source of anthraquinones which are wellknown as natural dyes, and are gaining importance in recent years due to environmental pollution caused by synthetic dyes. This paper attempts to give an overview of literature on the isolated and characterized anthraquinones from various Cassia species and their repoted applications. Besides dye yielding properties they are used in cosmetics and pharmaceuticals. Thus plants of Cassia species can serve as commercial source of naturaly occurring anthraquinones.

TL;DR: In this paper, subcritical water extraction was investigated as a benign alternative for solvent extraction of damnacanthal from the dried root of Morinda citrifolia, which has been used for treatment of chronic diseases such as cancer and heart disease.
122 citations
TL;DR: In this article, different plants, herbs and spices (158 samples) were tested in a screening trial to assess their potential to modify ruminal fermentation in vitro, in particular their effectiveness for decreasing methane production.
