(4) The optivity of annulene compounds abided by the helix law, that is, right handed helix is D-rotatory and left handed helix is L-rotatory.

(5) With the increase of the stress, the contents of 9 aromatic constituents like 1,6-methylene annulene increased, whereas those of 8 constituents as linalool decreased.

(6) The reaction mechanism of H2O2 dismutation catalyzed by a non-heme tetraaza annulene complex has been investigated by density functional theory using the B3LYP functional.

(7) But owing to the limit of the carbonaceous framework and difficulty of the raceme, so the derivatives of annulene show opticity activity.

(8) Different degrees of B. melanopus stress could induce the synthesis of 23 aromatic constituents like 1, 6-methylene annulene, but inhibit the formation of 6 constituents as nonanal .
