Constituents and antioxidant activity of two varieties of coconut water (Cocos nucifera L.)
Open accessAbstract
An analysis of the constituents of coconut (Cocos nucifera L.) water from two fruit varieties (green and yellow) by hydrodistillation and solvent extraction showed the presence of alcohols, ketones, thiols, carboxylic acids, phenols, and esters. Substantial antioxidant activity was observed, using the DPPH assay, for the samples obtained by hydrodistillation and petroleum ether extraction of both coconut varieties.

Alcohols, ketones, thiols, carboxylic acids, phenols and esters with short carbon chains were also detected in the essential oil of the coconut water, extracted by hydrodistillation and solvent extraction.
“Alcohols, ketones, thiols, carboxylic acids, phenols and esters with short carbon chains were also detected in the essential oil of the coconut water, extracted by hydrodistillation and solvent extraction [47].”
From Coconut water uses, composition and properties: a review (2012) · cites this paper as [47]
The Results and Discussion report alcohols, ketones and esters, as well as thiols and carboxylic acids in the hydrodistilled oil of the yellow variety. They do not report phenols; Table 1 also identifies a ten-carbon thiol and a sixteen-carbon acid, so the claim that all listed classes have short carbon chains is not supported. The paper analyzes both hydrodistillation and solvent extraction, but reports different compositions for the two methods. Page numbers are not provided in our copy. (LLM, conf=0.89)
Experimental — accuracy not yet measuredSubstantial antioxidant activity was observed using the DPPH assay for extracts of two green and yellow coconut varieties obtained by hydrodistillation and petroleum ether extraction.

From Coconut water uses, composition and properties: a review (2012) · cites this paper as [47]
The Results and Discussion section reports high DPPH radical-scavenging activity for hydrodistilled extracts from both green and yellow coconut water. It describes the petroleum ether extracts as having only moderate activity, so calling the activity of extracts from both methods substantial overstates the finding. (LLM, conf=0.88)
Experimental — accuracy not yet measuredFonseca et al. (2009) confirmed the presence of long chain fatty acids such as palmitic and oleic acids in green dwarf water, and the possibility that β-oxidation generated a slight rise of peroxide responsible for increasing intracellular ROS in the CW 1% group.

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.
