Spectroscopic and Thermooxidative Analysis of Organic Okra Oil and Seeds from Abelmoschus esculentus

Table 3

Signals of the Okra seed oil spectrum. The hydrogens were classified according to the displacement.

Signal	Displacement 𝛿 (ppm)	Multiplicity*	Functional group
A	0.88–0.78	m	–CH3 (saturated)
B	1.27–1.25	m	–(CH2)n– (fatty chain)
C	1.60–1.40	m	–CH2 (β to carbonyl)
D	2.05–1.98	m	–CH2 (allylic)
E	2.34–2.27	t	–CH2 (α to carbonyl)
F	2.79–2.73	t	–CH2 (bis-allylic)
G	4.32–4.08	ddd	–CH2 (glycerine)
H	5.09–5.36	m	–CH (vinylic) e –CH (glycerine)

*Multiplicity: doublet (d), double doublet (ddd), triplet (t), and multiplet (m).
