(Ranunculaceae Juss.) afforded a dilactone, anemonin (1) isolated, purified and identified by spectroscopic methods and comparison of their spectral data with the reported data.
Because of the investigation, a dilactone namely anemonin (1) was isolated and identified for the first time from P.
Valoneic acid dilactone
(aqueous Fl and F4), Hexoside (ethanol F4) and Coumaric acid (hexane F2) were identified as bioactive compounds in HPLC fractions.
hiiranensis, including elemane type, caryophyllene type, aromadendrene type, eudesmane type, and germacrane dilactone
type, are the main effective anti-inflammatory constituents .
Among the active compounds in SOL roots are saponin glycosides and ellagitannins such as pomolic acid, sanguisorbic acid dilactone
, and ziyuglycoside I (Kim et al.
Tannic Acid or Hydrolysable Tannins are naturally occurring complex phenol-rich polymers.12 They are described as heat-stable and water-soluble metabolites of plants with a molecular weight between 500 and 3000 Daltons.34 Tannic Acid is a water-soluble polyphenol containing sugar esters mainly glucose and phenol carboxylic acid such as Gallic acid hexahydroxydipenic acid or its stable dilactone
ellagic acid.567 It is found in a wide variety of plants and fruits and produced from secondary metabolism of these plants.
The detected mass of 912.36 for the [[M+H].sup.+] ion corresponded to SH in its dilactone
Xanthine oxidase inhibitors (valoneic acid dilactone
and ellagic acid) have been isolated from leaves of the plant (Unno et al., 2004).
Analgesic sesquiterpene dilactone
from Mikania cordata.
The in vitro antitrypanosomal activity of the germacranolide dilactone
of compound 1 could be due to the presence the [alpha]-methylene-[gamma]-lactone moiety.
Longipedlactones A-I, nine novel triterpene dilactones
possessing a unique skeleton from Kadsura longipedunculata.
