Overview

What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Botany
  • Enzyme

Osamu Tanaka spends much of his time researching Botany, Araliaceae, Traditional medicine, Glycoside and Dammarane. His research on Botany frequently connects to adjacent areas such as Diterpene. His Folk medicine and Triterpenoid study in the realm of Traditional medicine connects with subjects such as Pharmacognosy.

His Glycoside study necessitates a more in-depth grasp of Stereochemistry. His work on Carbon-13 NMR as part of general Stereochemistry research is frequently linked to Spectroscopy, bridging the gap between disciplines. Osamu Tanaka combines subjects such as Protopanaxatriol, Panax vietnamensis and Ginsenoside with his study of Dammarane.

His most cited work include:

  • 13C nmr study of α- and β-anomeric pairs of d-mannopyranosides and l-rhamnopyranosides (335 citations)
  • New sweet diterpene glucosides from Stevia rebaudiana (209 citations)
  • Carbon-13 chemical shifts of isoprenoid-β-D-glucopyranosides and -β-D-mannopyranosides. Stereochemical influences of aglycone alcohols (150 citations)

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

His primary areas of investigation include Botany, Glycoside, Stereochemistry, Traditional medicine and Araliaceae. The Rosaceae, Rhizome and Cucurbitaceae research Osamu Tanaka does as part of his general Botany study is frequently linked to other disciplines of science, such as Oleanane, therefore creating a link between diverse domains of science. His work carried out in the field of Glycoside brings together such families of science as Sweet taste, Sweetness and Diterpene.

Anomer is closely connected to Glycosylation in his research, which is encompassed under the umbrella topic of Stereochemistry. His Araliaceae research is multidisciplinary, relying on both Dammarane and Ginsenoside. His work on Sanchi ginseng as part of general Dammarane research is frequently linked to Panax notoginseng and Chromatography, thereby connecting diverse disciplines of science.

He most often published in these fields:

  • Botany (43.87%)
  • Glycoside (41.94%)
  • Stereochemistry (36.13%)

What were the highlights of his more recent work (between 1988-2009)?

  • Glycoside (41.94%)
  • Botany (43.87%)
  • Stereochemistry (36.13%)

In recent papers he was focusing on the following fields of study:

Osamu Tanaka spends much of his time researching Glycoside, Botany, Stereochemistry, Pharmacognosy and Traditional medicine. His work deals with themes such as Sweet taste, Sweetness and Diterpene, which intersect with Glycoside. His study in the field of Rosaceae, Rubus and Cucurbitaceae is also linked to topics like Oleanane.

His work in the fields of Terpenoid, Nuclear magnetic resonance spectroscopy and Glycosyl overlaps with other areas such as Iridoid Glucosides. His study in the field of Triterpenoid and Acanthaceae is also linked to topics like Apigenin and Important research. His studies examine the connections between Araliaceae and genetics, as well as such issues in Dammarane, with regards to Panax vietnamensis, American ginseng and Ginsenoside.

Between 1988 and 2009, his most popular works were:

  • Saponins from Vietnamese ginseng, Panax vietnamensis Ha et Grushv. Collected in central Vietnam. I. (104 citations)
  • N.m.r. spectral study of α- and β-l-arabinofuranosides (102 citations)
  • Bioactive saponins and glycosides. VIII. Notoginseng (1): New dammarane-type triterpene oligoglycosides, notoginsenosides-A, -B, -C, and -D, from the dried root of Panax notoginseng (BURK.) F. H. Chen (89 citations)

In his most recent research, the most cited papers focused on:

  • Organic chemistry
  • Botany
  • Enzyme

His scientific interests lie mostly in Glycoside, Stereochemistry, Pharmacognosy, Botany and Dammarane. His Glycoside study is related to the wider topic of Organic chemistry. His Stereochemistry study combines topics in areas such as Glycosylation and Glucosidases.

His Rhizome and Rubus study, which is part of a larger body of work in Botany, is frequently linked to Siraitia and Cucurbitane, bridging the gap between disciplines. His Neoalsomitra integrifoliola study in the realm of Dammarane interacts with subjects such as Panax notoginseng. His Taste study integrates concerns from other disciplines, such as Rosaceae and Diterpene.
