Sci Rep. 2017 Oct 23;7(1):13766. doi: 10.1038/s41598-017-14094-5.

Time-dependent density functional theory (TDDFT) and atoms in molecules (AIM) theory are combined to study the photoinduced excited state intramolecular proton transfer (ESIPT) dynamics for eight anthraquinones (AQs) derivatives in solution. The calculated absorption and emission spectra are consistent...

Ginger (Zingiber officinale) is a well-known and widely used herb, which contains several interesting bioactive constituents and possesses health-promoting properties. The proximate, mineral, antinutrient, amino acid, and phytochemical components of two varieties of ginger (Zingiber officinale) were investigated. Amino...

Identification and characterization of the ergochrome gene cluster in the plant pathogenic fungus .

Fungal biology and biotechnology

Neubauer L, Dopstadt J, Humpf HU, Tudzynski P.
PMID: 28955461
Fungal Biol Biotechnol. 2016 Mar 22;3:2. doi: 10.1186/s40694-016-0020-z. eCollection 2016.

RESULTS: This study identified the gene cluster responsible for the synthesis of the ergot pigments. Overexpression of the cluster-specific transcription factor led to activation of the gene cluster and to the production of several known ergot pigments. Knock out...

In the current study forty eight compounds belonging to anthraquinones, naphthoquinones, benzoquinones, flavonoids (chalcones and polymethoxylated flavones) and diterpenoids (clerodanes and kauranes) were explored for their antimicrobial potential against a panel of sensitive and multi-drug resistant Gram-negative and Gram-positive...

Evaluation of the palatability of chrysomelid larvae containing anthraquinones to birds.

Oecologia

Hilker M, Köpf A.
PMID: 28306931
Oecologia. 1994 Dec;100(4):421-429. doi: 10.1007/BF00317864.

Chrysomelid larvae of the subfamily Galerucinae, tribe Galerucini, are known to contain 1,8-dihydroxylated 9,10-anthraquinones. Since nonhydroxylated 9,10-anthraquinone is the active agent in several commercial products sold to protect seeds against birds, we suggested that the naturally occurring dihydroxylated anthraquinones...

Lipophilic Constituents of Rumex vesicarius L. and Rumex dentatus L.

Antioxidants (Basel, Switzerland)

Elfotoh MA, Shams KA, Anthony KP, Shahat AA, Ibrahim MT, Abdelhady NM, Azim NS, Hammouda FM, El-Missiry MM, Saleh MA.

Rumex dentatus L. and Rumex vesicarius L., of the family Polygonaceae, are edible herbs growing wild in Egypt. Their lipoid constituents were examined by both liquid chromatography/mass spectrometry (LC/MS) and by gas chromatography/mass spectrometry (GC/MS). Their essential oil compositions...

Anthraquinones in different developmental stages ofGaleruca tanaceti (Coleoptera, Chrysomelidae).

Journal of chemical ecology

Hilker M, Schulz S.
PMID: 24258609
J Chem Ecol. 1991 Nov;17(11):2323-32. doi: 10.1007/BF00988011.

The overwintering eggs and the larvae of the leaf beetleGaleruca tanaceti (L.) contain hydroxylated anthraquinones. In both developmental stages, l,8-dihydroxy-3-methylanthraquinone (= chrysophanol) and 1,8-di-hydroxyanthraquinone (= chrysazin) were detected by GC-MS and GC-FTIR analyses. In the eggs, chrysazin was found...

In the presence of the nonselective herbicide glyphosate (N-[phosphonomethyl]glycine), buckwheat (Fagopyrum esculentum Moench) hypocotyls and cultured cells of Galium mollugo L. accumulate an organic acid, which was identified as shikimate by mass-spectroscopy of its methyl ester. After growth in...
