Extraction of essential oil in Malva plants by steam distillation and


its benefits

ABSTARCT
Essential oils, extracted from various plant parts through methods like steam distillation and
solvent extraction, have a rich history dating back to ancient civilizations. Aromatherapists widely
advocate for their use, believing they offer diverse health benefits through inhalation or topical
application. This study delves into extracting essential oils from the Malva plant, also known as
mallow, aiming to explore their potential advantages. These oils are complex mixtures of volatile
compounds influenced by factors like seasonal variations, climate, and distillation techniques.
Chemical analyses have revealed the presence of compounds like malvone A, monoterpenes,
aromatic compounds, and flavonoids in Malva oils, highlighting their potential therapeutic value.
Malvone A, for example, has shown antiinflammatory properties in preliminary studies, suggesting
it could be beneficial for managing inflammatory conditions. Monoterpenes contribute to the
aromatic profile of Malva oils and may have antimicrobial properties, making them useful in natural
cleaning products or as topical antiseptics. Aromatic compounds not only lend pleasant scents
but also have potential mood-enhancing effects, making Malva oils popular in aromatherapy.
Flavonoids, known for their antioxidant properties, could play a role in protecting cells from
oxidative stress and supporting overall health. Understanding the specific compounds present in
Malva oils allows us to appreciate their multifaceted benefits. From promoting relaxation and
reducing stress to potentially aiding in skincare and supporting respiratory health, Malva oils offer
a holistic approach to wellness. This comprehensive exploration not only sheds light on the
therapeutic potential of Malva but also underscores the importance of considering plant-derived
remedies in modern healthcare practices.

In the example above, freshwater is the liquid being extracted. As heat from the Bunsen
burner flame is applied to the flask, which contains seawater, the water boils and
evaporates. The water vapor is cooled and redirected by the condenser to the Erlenmeyer
flask, drip by drip.
The flowing water in the outer cooling tube surrounding the inner condensing tube
facilitates the condensation of the water vapor. Since salt is solid and has a very high boiling
point, it doesn't evaporate with the water. As a result, the distillate is freshwater (5)..

Extensive research shows that this plant, with different chemical compounds, can minimize
liver damage caused by carbon tetrachloride. M. sylvestris has antimicrobial,
antinociceptive, hepatoprotective, wound-healing, anticancer, anti-inflammatory, and
potent antioxidant properties . Also, this plant contains many valuable compounds such as
strong antioxidants and carbohydrates and unsaturated fatty acids. Tannins, flavonoids,
phenolic compounds, and ascorbic acid found in the Malva plant are used to treat most
cancers and for wound-healing(8).

Assessment of the leaves of M. sylvestris has shown the presence of essential and
nonessential metallic elements, halogens, and nonmetals. Analysis was performed using
plasma optical emission spectrometry (ICP-OES), and the presence of Zr, Zn, U, Tl, Sr, Pb,
Ni, Na, Mn, Mg, Sn, La, K, Si, Fe, Cu, Cr, Co, Ca, Bi, Ba, B, and Al was also shown
[16]1. M. sylvestris has exhibited a considerable ability to accumulate substantial metals
(Zn, Pb, Ni, Cu, and Cd) from soils rich in these materials. Thus, it is crucial to address
this issue in affected populations living in hazardous zones And A major phytoalexin found
in M. sylvestris was 2-methyl-3-methoxy-5,6-dihydroxy-1,4-naphthoquinone, known as
malvone(8).

Extensive research shows that this plant, with different chemical compounds, can minimize
liver damage caused by carbon tetrachloride. M. sylvestris has antimicrobial,
antinociceptive, hepatoprotective, wound-healing, anticancer, anti-inflammatory, and
potent antioxidant properties . Also, this plant contains many valuable compounds such as
strong antioxidants and carbohydrates and unsaturated fatty acids. Tannins, flavonoids,
phenolic compounds, and ascorbic acid found in the Malva plant are used to treat most
cancers and for wound-healing(8).

Assessment of the leaves of M. sylvestris has shown the presence of essential and
nonessential metallic elements, halogens, and nonmetals. Analysis was performed using
plasma optical emission spectrometry (ICP-OES), and the presence of Zr, Zn, U, Tl, Sr, Pb,
Ni, Na, Mn, Mg, Sn, La, K, Si, Fe, Cu, Cr, Co, Ca, Bi, Ba, B, and Al was also shown
[16]1. M. sylvestris has exhibited a considerable ability to accumulate substantial metals
(Zn, Pb, Ni, Cu, and Cd) from soils rich in these materials. Thus, it is crucial to address
this issue in affected populations living in hazardous zones And A major phytoalexin found
in M. sylvestris was 2-methyl-3-methoxy-5,6-dihydroxy-1,4-naphthoquinone, known as
malvone(8).
