Radical scavenging activity of phenylpropanoid glycosides in Caryopteris incana.
In our screening program for antioxidants from traditional drugs and foodstuffs, one new phenylpropanoid glycoside, incanoside, was isolated together with four known phenylpropanoid glycosides,
Two interchangeable forms of ciguatoxin.
TLDR
A series of chromatographies showed that the two components of ciguatoxin are interchangeable, which proves that cigu atoxin is a single molecular entity.
RECENT DEVELOPMENTS IN THE MOLECULAR STRUCTURE OF CIGUATOXIN
TLDR
Chromatographic evidence suggests that the two toxins are identical with the two ciguatoxins of different polarity and that the less polar form is the previously described scaritoxin.
Fumiquinones A and B, Nematicidal Quinones Produced by Aspergillus fumigatus
TLDR
New nematicides named fumiquinones A and B were isolated from Aspergillus fumigatus and their structures were established by spectroscopic methods including 2D-NMR to show effective nematicidal activities against B. xylophilus without any plant growth inhibition.
Novel Fusicoccins R and S, and the Fusicoccin S Aglycon (Phomopsiol) from Phomopsis amygdali Niigata 2-A, and Their Seed Germination-stimulating Activity in the Presence of Abscisic Acid
Our search for new 3-hydroxyfusicoccins structurally related to cotylenin A from a culture of Phomopsis amygdali Niigata 2-A resulted in the isolation of novel 3-hydroxy fusicoccins, called
