Abstract
The leaf oil of Alchornea tiliifolia (Benth.) Muell. produced from plants growing in Pu Mat National Park,
Nghean province, Vietnam was prepared by steam distillation. The oil was analyzed by GC and GC/MS. A total of 45
compounds were identified, of which b-pinene (31.4%), linalool (17.0%) and b-caryophyllene (10.7%) were found
to be major components.

Introduction


Experimental

The Euphorbiaceae family consists of about 317 genera and
5000 species which are widespread, primarily in the tropics and
subtropics, poorly represented in temperate regions (1). About
70 genera and 460 species are distributed in Vietnam (2).
Many species of Euphorbiaceae are of economic importance, such as sources of medicine, provisions, paint, rubber,
insecticides, etc. (1,3).
Alchornea tiliifolia (Benth.) Muell. (Local name: Dom
dom la day) (syn. Stipellaria tiliifolia Benth.) is one of the 60
species belong to the genus Alchornea, distributed in Son La,
Cao Bang, Quang Ninh, Bac Can, Tuyen Quang, Phu Tho, Ha
Tay provinces, Vietnam (2); India, China, Laos, Cambodia,
Malaysia and Thailand (3).
In the course of the systematic study of Alchornea species
in Indochina, mono-, sesquiterpenes and other components
of the leaf oil of A. tiliifolia from Nghean province, Vietnam
have been investigated.

Source: Alchornea tiliifolia (Euphobiaceae) is a shrub tree
that can grow up to 1–3 m high in Vietnam. Leaves were collected in Pu Mat National Park, Nghean province. A voucher
specimen (DD4) has been deposited in the Herbarium of the
Institute of Ecology and Biological Resources, Vietnamese
Academy of Science and Technology.
Fresh leaves were shredded and their oil was obtained by
steam distillation for 3 h at normal pressure, according to the
Vietnamese Pharmacopoeia (4). The yield of the fresh leaf oil
was 0.22%.
GC: About 15 mg of oil, which was dried over anhydrous
sodium sulfate, was dissolved in 1 mL of CH3OH (for spectroscopy or for chromatography).

GC analysis was performed on a HP 6890 Plus Gas chromatograph equipped with a FID and fitted with a 25 m x 0.25
mm x 0.25 mm film thickness HP-5MS column. The analytical
conditions were: carrier gas H2 with flow rate 35 cm/min, injec-

tor temperature (PTV) 250°C, detector temperature 260°C,
temperature programmed 60°C (2 min hold) to 220°C (10
min hold) at 4°C/min. The relative percentage amounts of the
separated compounds were computed from FID data without
the use of correction factors.
GC/MS: A Hewlett Packard 6890 Plus Chromatograph
was fitted with the same fused silica HP-5MS capillary col-

lumn. The conditions of use were the same as described above
except that He was the carrier gas with flow rate 30 mL/min,

and there was an interface with a mass spectrometer HP 5972
MSD (70 eV). The temperature was programmed as reported
above. Component identification was carried out by comparing
MS data with those reported in Wiley Library on Chemstation
HP, and in some cases substances identified from oils known
composition and also with standard substances (5–10).

The leaf oil of A. tiliifolia from Vietnam, obtained in 0.22%
yield was composed entirely of mono- and sesquiterpenes.
Forty-five components were identified in the oil (Table I).
The main components were b-pinene (31.4%), linalool (17.0%)
and b-caryophyllene (10.7%). These compounds accounted for
59.1% of the oil. These main compounds and other oxygenated
components such as 1,8-cineole, nonanal, a-fenchol, borneol,
terpinen-4-ol, a-terpineol, myrtenol, neryl formate, nerolidol,
caryophyllene oxide, bisabolol oxide B, eudesmol and farnesol
contribute to the characteristic aroma of the leaf oil.
Other less predominant compounds were a-pinene (8.4%),
a-bisabolene (4.3%) and farnesol (5.9%).
To the best of our knowledge until now no publication on
chemical composition of the essential oil of this species has
been published.
