TL;DR: A new flavanone with epoxy-isopentyl moiety named parkintin has been isolated from the methanol soluble part of Parkinsonia aculeata Linn belonging to the family Caesalpiniaceae.

TL;DR: Sanggenon B (I) as mentioned in this paper is a variation of a Diels-Alder adduct of a chalcone derivative and a dehydroprenylflavanone derivative.
Abstract: From the benzene extract of the Chinese crude drug "Sāng-Bai-Pi" (Japanese name Sōhakuhi), the root barks of Morus sp. (Moraceae), a novel isoprene substituted flavanone derivative, named Sanggenon B, was isolated; its structure was shown to be I on the basis of spectral and chemical data. Sanggenon B (I) is regarded biogenetically as a variation of a Diels-Alder adduct of a chalcone derivative and a dehydroprenylflavanone derivative.

TL;DR: In this article, two new flavanones, leachianones D and E, were isolated from the roots of Sophora leachiana together with maackiain and a caffeic acid ester.

TL;DR: The structure of new compound IXNOX was established using (1)HNMR, (13)C NMR, IR and UV-VIS spectroscopy, by comparison to IXN, NOX and FLOX, and showed a strong antioxidant activity comparable to that of ascorbic acid.

TL;DR: Vegetables and fruits rich in flavonoids have become integral and even necessary in the animal diet, suggesting that flavonoid may have developed to play beneficiary roles for not only the plants themselves but also the predator animals.
Abstract: Flavonoids are abundant in plants as secondary metabolites where they have antioxidant activities. The diverse and non-specific inhibition of several enzymes, including avian myeloblastosis virus reverse transcriptase (RT), human immunodeficiency virus (HIV) RT, murine leukemia virus RT, HIV-1 protease, trypsin and elastase, were tested for by observing the effects of several flavonoid compounds. Some of the flavonoids were reconfirmed as antiretroviral agents as previously shown by others. Flavonoids belonging to the flavonol or flavone group simultaneously inhibited reverse transcriptases and proteases. On the contrary, flavonoids belonging to the flavanol, isoflavone or flavanone group were less likely to inhibit reverse transcriptase or protease. Vegetables and fruits rich in flavonoids have become integral and even necessary in the animal diet, suggesting that flavonoids may have developed to play beneficiary roles for not only the plants themselves but also the predator animals.
