Other substances found in anise oil are anisaldehyde
dianethole anisketone anisic acid p-methoxy acetophenone -himachalene and cis-anethole.
LiP alone is practically not able to oxidize 4-methoxymandelic acid, 4-MMA to anisaldehyde
, but these oxidations take place with good efficiency in the presence of VA (Arora and Gill, 2001; Gassara et al.
Visualization of spots on TLC were under UV lamp, in iodine chamber and with anisaldehyde
spray followed by heating in the oven.
Theoretical values of ultrasonic velocities in the mixtures: anisaldehyde
+ o-xylene, + m-xylene and + p-xylene at different mole fractions of anisaldehyde
for different temperatures were calculated using the following theories and relations:
Anise oil has anothole (85 %) as active ingredient and also it has contained eugenol, methylchavicol, anisaldehyde
The spots were visualized by heating with anisaldehyde
at 105[degrees]C on a hot plate.
The compound gave a yellow spot with anisaldehyde
spray reagent after heating at 110 [degrees]C for 2-3 min.

The present work is related to the preparation and characterization of Nickel (II) complexes of semicarbazone and thiosemicarbazone of anisaldehyde
170 [degrees] C, and anisaldehyde
phenyl hydrazone (APH) m.
5:1 [v/v/v/v] and detected at 690 nm after derivatization with anisaldehyde
sulphuric acid spray reagent.
On TLC the compound gave a violet spot with p-nitroaniline spray reagent indicating that it is either phenolic or enolic, a dark brown colour with anisaldehyde
spray reagent and a bright yellow colour with, 2,4 DNP spray reagent, suggesting that a carbonyl group might be present.
