ABSTRACT
Fragrance was a common material in human daily life. It has unique property, especially in
odor. Lyrame was a synthetic precursor that was added to fragrance to increase fragrance stability
and make odor last longer. Lyrame can be synthesized by using simple condensation method.This
method was effective and low cost. The synthesis of lyrame uses lyral and methyl anthranilate as a
precursor. The weighting methyl anthranilate was mixed to lyral solution, then heated and stirred at
temperature 110 50C for 30 minutes.The characterization of lyrame comprised organoleptics test
and chemical structure. The organoleptics for product was color test. The chemical structure was
analyzed by gas chromatography-mass spectrometry (GC-MS). Based on result from experiment,
color of lyrame product was light yellow. The color of product depends on time of synthesis and
concentration of precursor. The mass fragmentation pattern exhibiting the lyrame has been
synthesized successfully.

INTRODUCTION
chain. Nowadays, synthetic precursor has been
used to subtitute the natural source as a main
ingredient3.
The majority of personal-care such as
cosmetic and perfumes contains fragrances in their
ingridients1. Fragrance contains many components
which have generated special properties, especially
in odor. Ingredient of fragrance usually contains
synthetic precursor or natural extract which is diluted
in alcohol. Natural precursor provides unique odor2,
but it has not been priority today due to dependence
on weather condition which can disrupt the supply
Quality of fragrance can be known from
some properties, like odor, color, volatility, and
other physical chemical stabilities4,5,6. Generally, a
synthetic precursor is a Schiff Base like aurantiol4,
verdantiol, cyclantin, jasmea, and the most promising
lyrame is added to escalate the quality of fragrances.
Molecular weight of lyrame is bigger than other

10 cm), then panelist wrote some codes to identify
the solution. Panelist’s eyes must be parallel with
the tube, when they did the test.The room condition
must have good light exposure and no reflection to
increase the test accuracy.
Aldehyde compound is reacted with amine
trapping agent in condensation reaction to form
Schiff base and water as a by-product. Water must
be eliminated to prevent turbidity and two phases
formed in product solution. Generally, eliminating
water from product occurs under vacuum, instead
using high temperature at atmospheric pressure to
prevent Schiff bases product is not decomposing3.

diluted by ethanol, then analysed using GC-MS.The
analysis on condition of GC–MS could be seen at

confirmed by comparing fragmentation result with
existing library.

Fig. 1. The formation reaction of Schiff base
Methyl anthranilate was often used as
amine trapping agent in Schiff base’s synthesis.
Methyl anthranilate generally gives Schiff bases
that are yellow solid or viscous, yellow liquid. An
excess methyl anthranilate was used to make Schiff
base become more liquid. Methyl anthranilate is a
primary amine which will react spontaneously with an
alkyl aldehyde7, terpened aldehyde7,8, or terpened-like
aldehyde7 such as lyral. When methyl anthranilate
reacts with lyral, Schiff base called lyrame is formed.

RESULT AND DISCUSSION
Lyrame was produced by simple
condensation reaction. Amine group in methyl
anthranilate would act as a nucleophillic, attacking
the carbonyl group in lyral by 1,2 addition, then
hydroxyl group was protonized and eliminated water
molecules. The lyrame mechanism synthesis is
shown at Figure 2.
Gaschromatograpyandmassspectrometry
(GC-MS) have been the most important techniques
in the perfumes industry because perfume ingridient
is quite complex, a polar, and (semi) volatile9,10,11
.
In this study, we aim to prepare lyrame Schiff Base
using simple condensation reaction and to analyze
spectral molecular ion fragment to ensure molecular
structure lyrame Schiff base using GC-MS.

Lyrame Schiff base has a high molecular
weight, meaning it has good physical and chemical
stabilities, but poor solubility in water.In order to speed
up the reaction, the synthesis was carried out at high
temperature and stirred in hot plate. Furthermore,
this process also prevented the solution turbid and
formed two phases.Water would evaporate because
the synthesis temperature was higher than boiling
temperature of water. Stirring process during the
synthesis would accelerate movement of water
molecule, so would evaporate easily. The product
solution was a bright yellow as shown in Figure 3.

component was listed inTable 2.The reactant methyl

12.513 min. and 12.571 minutes. It indicated that
the lyrame formation was not completion. Lyral has
two E-Z isomer configurating at its cyclic structure
which shown in Figure 512.

Steric hindrance was an interaction
that influenced the conformation in the organic
molecules. Steric hindrance was a critical factor to
determine the reactivity and stability in molecular
structure13. The molecule has less reactive in
bulky molecules14. Z-lyral has less steric hindrance
than E-lyral, so Z-lyral would have more reactive
than other isomer. It was proved with the unequal
percentage of composition between isomers.Lyrame
peak was shown at 22.350 min.and 23.371 minutes.
It exhibited that all lyral isomers could react with
methyl anthranilate to form lyrame.

Color test was an important parameter for
physical characterization in lyrame synthesis. Test
was performed by trained panelist. The standard
solution which used lyrame standard solution was
made in PT Nilam Widuri. Time for synthesis of
lyrame standard solution was 2 hours. Fig. 3. shows
that color in lyrame was light yellow. The lyrame
product was brighter than standard, it was shown
that color solution directly proportional with time of
lyrame synthesis.

Formula
The concentration of methyl anthranilate
was also a crucial factor to determine color the Schiff
base. High concentration of methyl anthranilate
gave a brighter color of solution and made product
less viscous. Furthermore, another crucial factor
determining the quality of product (brigthness of
solution) was the degree of completion of reaction.

Molecular structure of lyrame was
investigated by using ion fragment from mass
spectrometry. Fig. 6 shows that mass spectral for
lyrame product m/z 343 was similar with lyrame’s
molecular mass and m/z 119.0 was the base peak.
Mass spectra m/z 325 was originating from alpha
cleavage releasing H2O molecule. There were two
possibilities of carbocation in m/z 325 tertiary and
secondary positions. Double homolytic cleavages
occurred in tertiary carbocation to produce C3H5+
which was shown as m/z 41. At secondary
carbocation experiences the homolytic cleavage
and C4H7+ were made. It was proved by peak of m/z
55 risen in fragmentation spectrum. Another route
radical cleavage of secondary carbocation would
release C5H9 radical and it was proved by peak of m/z
256 in the mass spectrum. Releasing -:CH2 in next
homolytic cleavage, made high peak of m/z 242 arise.
Molecular ion C15H16NO2+ experience carbocation
rearranged and followed by simultaneous heterolytic
cleavage to release HCOOCH3. The peak of
+
m/z 77 was originating from C6H5 which was
rising after releasing C7H7N radical. The base peak
+
of m/z 119 was originating from C8H6O2 which
experienced homolytic cleavage to form C7H3O2+ and
released methyl radical. Pattern of lyrame’s mass
fragmentation can be seen in Figure 6.

CONCLUSION
chromatogram due to lyral as precursor has two
isomers that can be reacted with methyl anthranilate.
Base peak in the lyrame fragment in m/z 119 is
formed from homolytic cleavage C8H6O2+ and the
parental ions of lyrame fragment in m/z 343.
Lyrame Schiff base was succesfully
synthesized by simple condensation method.
The color of lyrame was directly proportional with
time of synthesis. The degree of completion and
concentration of methyl anthranilate also was
crucial factor that affected the color of product.
High concentration of methyl anthranilate made
the product less viscous and the color of solution
was brighter. Lyrame structural molecules has had
been confirmed with GC-MS mass fragmentation
pattern. There are two peaks of lyrame product in
