Microwave-assisted hydrodistillation of essential oil from rosemary
Open accessAbstract
Effects of microwave assisted hydrodistillation (MAHD) and conventional hydrodistillation (HD) methods on yield, composition, specific gravity, refractive index, and antioxidant and antimicrobial activities of essential oil of Rosmarinus officinalis L were studied. The main aroma compounds of rosemary essential oil were found as 1,8-cineole and camphor. Trolox equivalent antioxidant capacity (TEAC) values for essential oils extracted by MAHD and HD were 1.52 mM/ml oil and 1.95 mM/ml oil, respectively. DPPH radical scavenging activity of the oils obtained by MAHD and HD were found as 60.55% and 51.04% respectively. Inhibitory effects of essential oils obtained by two methods on linoleic acid peroxidation were almost the same. Essential oils obtained by two methods inhibited growth of Esherichia coli O157:H7, Salmonella typhimurium NRRLE 4463 and Listeria monocytogenes Scott A with the same degree. However, inhibitory activity of essential oil obtained by MAHD on Staphylococcus aureus 6538P was stronger than that of obtained by HD (p < 0.05).

Each is checked against this paper’s own text: does it say what the citing paper says it does?
The sharp yield drop at too low pressure is probably because volatile components and essential oils did not have enough time to cross the cell wall and mass transfer.
“It is probably because volatile component and essential oils did not have enough time to cross the cell wall and mass transfer (Karakaya et al., 2014).”
From Optimization of essential oil extraction from orange peels using steam explosion (2018) · cites this paper as Karakaya et al., 2014
The Essential oil yield section says extraction takes time and that microwave heating creates a high internal pressure gradient that ruptures cell walls, allowing oil extraction. The Composition section also says some constituents need more time to reach their maximum levels. Neither section attributes a sharp yield drop at low pressure to insufficient time for components to cross cell walls or undergo mass transfer. (LLM, conf=0.83)

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.
