The purified, active compound was identified as eugenol (4-allyl-2-methoxyphenol), the major component of clove oil. Eugenol fully inhibited TMEM16A Cl(-) conductance with single-site IC(50)~150 uM. Eugenol inhibition of TMEM16A in interstitial cells of Cajal produced strong inhibition of intestinal contraction in mouse ileal segments.

EUGENOL 161 3.7 3.7.1 Spectroscopy UVNIS Spectroscopy The ultraviolet absorption of eugenol was recorded on a HP 8452A diode array spectrophotometer. The spectrum obtained in alkaline solution (0.1 N NaOH) is shown in Figure 2, and was characterized by an absorption maximum at 296 nm. The following are the IR spectra of two eugenol samples (A and B) obtained from experiment 6. (a) Identify all the characteristic IR signals in the spectra that would support both A and B are eugenol. Make sure to indicate both the bonds that give the signals and their corresponding frequencies.

The presence of two peaks in the carbonyl range (1630-1850 cm-1) indicates either the presence of an "anhydride type" of function or two different carbonyl functions (i.e., conjugated and saturated ketone (see exampke 1)). These peaks can vary grealy in terms of their relative intensities. 6. 1H NMR Spectrum (HMDB0005809) Spectrum Details. HMDB ID: HMDB0005809: Compound name: Eugenol: Spectrum type: 1H NMR Spectrum: Spectrum View. Spectra Viewer The IR spectrum compares closely with a reference spectrum for Eugenol, further confirming that the IR spectrum shows the presence of Eugenol.

Eugenol 500g (purity 99%) was purchased from the Aldrich Chemical Co. Ltd, England. The identity and purity of the chemical were established by comparison of the IR spectrum with published data and by GLC. Further details not reported.

Obtain an IR spectrum of the purified eugenol. For the report: 1. Calculate the amount of eugenol per gram of cloves. 2.

Eugenol is a phenylpropanoid formally derived from guaiacol with an allyl chain substituted para to the hydroxy group. It has a role as an allergen, a plant metabolite, a human blood serum metabolite and a sensitiser.

it did not come out that good but i need to label ALL peaks(even if not visible on my worksheet) that eugenol has. Can you please label ALL corresponding peaks on eugenol based on my sheet.
