Abstract

The decoction of Cocos nucifera L. husk fiber has been used in northeastern Brazil traditional medicine for treatment of diarrhea and arthritis. Water extract obtained from coconut husk fiber and fractions from adsorption chromatography revealed antimicrobial activity against Staphylococcus aureus. The crude extract and one of the fractions rich in catechin also showed inhibitory activity against acyclovir-resistant herpes simplex virus type 1 (HSV-1-ACVr). All fractions were inactive against the fungi Candida albicans, Fonsecaea pedrosoi and Cryptococcus neoformans. Catechin and epicatechin together with condensed tannins (B-type procyanidins) were demonstrated to be the components of the water extract.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Monolaurin exhibits antiviral and antifungal activity.

    “Cellular studies have also shown that monolaurin exhibits antiviral and antifungal activity [78].”
  • Meneguetti et al. (2017) and Esquenazi et al. (2002) reported the presence of several phenolic compounds in coconut including Catechin and salicylic acid in the CW and gallic, caffeic, salicylic, and p-coumaric acids in the meat.

    “Meneguetti et al. (2017) and Esquenazi et al. (2002) reported the presence of several phenolic compounds in coconut including Catechin and salicylic acid in the CW and gallic, caffeic, salicylic, and p-coumaric acids in the meat.”
  • Others have reported antiviral and antibacterial activities in coconut due to lauric acid and other antimicrobial components.

    “Others have reported antiviral and antibacterial activities due to the presence of lauric acid and other antimicrobial components (Cruz et al., 2014;Esquenazi et al., 2002;Meneguetti et al., 2017;Sarika and Rai, 2012;Sheri et al., 2006).”
  • In Brazil, extract from the husk fiber of C. nucifera is used to treat diarrhea.

    “In Brazil, extract from the husk fiber of C. nucifera is used to treat diarrhea (7).”
  • The antifungal, antimicrobial, and antiviral effects were attributed to condensed tannins and catechins present in the crude extract and fractions II-V, especially fraction II.

    “The antifungal, antimicrobial, and antiviral effects were attributed to condensed tannins and catechins present in the crude extract and fractions II-V, especially fraction II, which had a higher concentration of these compounds.”

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.
