Structural Identification of a Major Cytokinin in Coconut Milk as 14-O-{3-O-(.BETA.-D-Galactopyranosyl-(1.RAR.2)-.ALPHA.-D-galactopyranosyl-(1.RAR.3)-.ALPHA.-L-arabinofuranosyl)-4-O-(.ALPHA.-L-arabinofuranosyl)-.BETA.-D-galactopyranosyl}-trans-zeatin Riboside.
Open accessAbstract
A cytokinin isolated from the fluid endosperm of Cocos mucifera L. (coconut milk), accounting for more than 20% of the total cytokinin activity, was structurally analyzed by NMR techniques, mass spectrometry, and sugar analysis by high performance liquid chromatography (HPLC). The planar structure of the cytokinin was deduced from its NMR and mass spectrometric data. The structure of the sugar moiety, including its absolute structure, was determined by HPLC analysis of alditol acetates and aldononitrile acetates derived from the cytokinin. The configuration of the sugar-sugar bonds was determined by NMR, and the structure was finally identified as 14-O-(3-O-[-beta-D-galactopyranosyl-(1-->2)-alpha-galactopyranosyl-(1--> 3)- alpha-L-arabinofuranosyl]-4-O-(alpha-L-arabino-furanosyl)-beta-D- galactopyranosyl)-trans-zeatin riboside.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
Coconut water contains auxin, various cytokinins, GAs and ABA (Table 2).
“Coconut water contains auxin, various cytokinins, GAs and ABA (Table 2) [4,32,33,34,35].”
From The Chemical Composition and Biological Properties of Coconut (Cocos nucifera L.) Water (2009) · cites this paper as [4]
The paper identifies a cytokinin in coconut milk (p. 1), and the Discussion (p. 4) reports several other substances with cytokinin activity. It does not establish that coconut milk also contains auxin, gibberellins (GAs), or ABA; its general mention of auxins and gibberellins does not place them in coconut milk. (LLM, conf=0.87)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
