Overview

What is he best known for?

The fields of study Isao Kouno is best known for:

  • Enzyme
  • Phenols
  • Flavonoid

His work in Phyllanthus emblica tackles topics such as Traditional medicine which are related to areas like Phyllanthus. His study on Phyllanthus is mostly dedicated to connecting different topics, such as Traditional medicine. In the field of Catechin, Proanthocyanidin, Theaflavin, Hydrolyzable Tannin, Epigallocatechin gallate and Ellagitannin Isao Kouno studies Polyphenol. While working on this project, he studies both Epigallocatechin gallate and Polyphenol. In his articles, he combines various disciplines, including Antioxidant and Enzyme. He performs multidisciplinary study in Enzyme and Antioxidant in his work. His work in Organic chemistry is not limited to one particular discipline; it also encompasses Pigment. His Stereochemistry study frequently draws connections between adjacent fields such as Glycoside. His Glycoside study frequently links to other fields, such as Stereochemistry.

His most cited work include:

  • Facile Discrimination of Aldose Enantiomers by Reversed-Phase HPLC (682 citations)
  • Antimicrobial Activity of 10 Different Plant Polyphenols against Bacteria Causing Food-Borne Disease (397 citations)
  • Antibacterial Spectrum of Plant Polyphenols and Extracts Depending upon Hydroxyphenyl Structure (242 citations)

What are the main themes of his work throughout his whole career to date

His Stereochemistry study frequently involves adjacent topics like Glycoside. His Glycoside study frequently involves adjacent topics like Stereochemistry. His studies link Enzyme with Organic chemistry. Isao Kouno regularly links together related areas like Organic chemistry in his Enzyme studies. His studies link Biochemistry with Antioxidant. His Biochemistry study frequently links to adjacent areas such as Polyphenol. He undertakes multidisciplinary studies into Polyphenol and Antioxidant in his work. His Pathology study frequently draws connections to other fields, such as Alternative medicine. His Pathology research extends to the thematically linked field of Alternative medicine.

Isao Kouno most often published in these fields:

  • Stereochemistry (67.57%)
  • Organic chemistry (63.51%)
  • Antioxidant (42.57%)

What were the highlights of his more recent work (between 2011-2016)?

  • Stereochemistry (66.67%)
  • Organic chemistry (55.56%)
  • Traditional medicine (44.44%)

In recent works Isao Kouno was focusing on the following fields of study:

His Phyllanthus emblica research focuses on Traditional medicine and how it connects with Officinalis and Phyllanthus. His research is interdisciplinary, bridging the disciplines of Traditional medicine and Officinalis. As a part of the same scientific family, Isao Kouno mostly works in the field of Green tea, focusing on Food science and, on occasion, Fermentation. His study on Fermentation is mostly dedicated to connecting different topics, such as Food science. As part of his inquiry into Ellagitannin and Catechin, Isao Kouno is doing Polyphenol research. Isao Kouno integrates Catechin with Polyphenol in his study. His research brings together the fields of Two-dimensional nuclear magnetic resonance spectroscopy and Stereochemistry. Two-dimensional nuclear magnetic resonance spectroscopy is closely attributed to Stereochemistry in his work. His study in Benzyl benzoate extends to Organic chemistry with its themes.

Between 2011 and 2016, his most popular works were:

  • Transformation of tea catechins and flavonoid glycosides by treatment with Japanese post-fermented tea acetone powder (26 citations)
  • Formation and Conformation of Baicalin–Berberine and Wogonoside–Berberine Complexes (18 citations)
  • Two new phenolic glucosides and an ellagitannin from the leaves of Castanopsis sclerophylla (16 citations)
