Eight compounds, namely 2-heptanone
(2), 1-heptanol (7), 3-octanone (8), ethyl hexanoate (10), 2-ethylhexan-1-ol (13), ethyl octanoate (27), (E)-[alpha]-bergamotene (34), and (E,E)-[alpha]-farnesene (36) were shared by the aeration extracts and salivary-gland extracts of the mango and starfruit populations and together generated 63.
The natural anaesthetic is 2-heptanone
(2-H), a compound found in many foods and also secreted by certain insects, but never before understood to have anaesthetic properties.
Scientists found 2-heptanone
(2-H), a natural compound found in many foods as well as insects, in the bite.

, ionone, 2-heptanol, hexanal, cis-3-hexenol, trans-2-hexenol and furaneol to be the major aroma compounds in Black Diamond.
It has been observed that decanal and 2-undecanone was found in equal proportion and was closely followed by hexadecane while 2-heptanone
was found in the least amount (Fig.
