“…The most active ingredients are 1,8-cineole, linalool, and terpinen-4-ol. Its effect is comparable to that of tea tree oil [63]. At a concentration of 0.2–0.4%, cajuput oil inhibits the growth of Gram-positive bacteria: Bacillus cereus, Bacillus subtilis, Corynebacterium diphtheriae, Corynebacterium minutissimus, Enterococcus faecium, Listeria monocytogenes [56], Micrococcus luteus, Staphylococcus aureus, S. capitis, S. epidermidis, S. faecalis, Klebsiella spp.…”

Herbs and the essential oils derived from them have been used from the beginning of human history for different purposes. Their beneficial properties have been applied to mask unpleasant odors, attract the attention of other people, add flavor and aroma properties to prepared dishes, perfumes, and cosmetics, etc. Herbs and essential oils (EOs) have also been used in medicine because of their biological properties, such as larvicidal action, analgesic and anti-inflammatory properties, antioxidant, fungicide, and antitumor activities, and many more. Many EOs exhibit antimicrobial properties, which is extremely important in fields of science and industry, such as medicine, agriculture, or cosmetology. Among the 250 EOs which are commercially available, about a dozen possess high antimicrobial potential. According to available papers and patents, EOs seem to be a potential alternative to synthetic compounds, especially because of the resistance that has been increasingly developed by pathogenic microorganisms. In this review we summarize the latest research studies about the most-active EOs that are known and used because of their antimicrobial properties. Finally, it is noteworthy that the antimicrobial activities of EOs are not preeminent for all strains. Further investigations should, thus, focus on targeting EOs and microorganisms.

“…In particular, medicine derived from natural and safe herbs is one of the research directions that deserve attention. Given the abundant supply in Vietnam and the specific healing properties of Melaleuca cajuputi, [2] we recommend a solution for prevention of SARS-CoV-2 by using cajeput essential oil. Melaleuca cajuputi (Figure 1) is one of hundreds species of Melaleuca genus (Myrtaceae family) that is commonly grown in Vietnam, Indonesia, and Thailand.…”

GC-MS was applied to identify 24 main substances in Melaleuca cajuputi essential oil (TA) extracted from fresh cajeput leaves through steam distilling. The inhibitory capability of active compounds in the TA from Thua Thien Hue, Vietnam over the Angiotensin-Converting Enzyme 2 (ACE2) protein in human body -the host receptor for SARS-CoV-2 and the main protease (PDB6LU7) of the SARS-CoV-2 using docking simulation has been studied herein. The results indicate that the ACE2 and PDB6LU7 proteins were strongly inhibited by 10 out of 24 compounds accounting for 70.9% in the TA. The most powerful anticoronavirus activity is expressed in the order: Terpineol (TA2) � Guaiol (TA5) � Linalool (TA19) > Cineol (TA1) > β-Selinenol (TA3) > α-Eudesmol (TA4) > γ-Eudesmol (TA7). Interestingly, the synergistic interactions of these 10 substances of the TA exhibit excellent inhibition into the ACE2 and PDB6LU7 proteins. The docking results orient that the natural Melaleuca cajuputi essential oil is considered as a valuable resource for preventing SARS-CoV-2 invasion into human body.

“…So that, the number of chemical components of cajuput oil from Papua was the lowest than the others because the environment stress was low. Chemical components in cajuput oil that have antimicrobial activity was 1,8-cineole, (-) -Linalool, (-) -4-Terpineole, and (±) -α-terpineole [9]. It is confirmed that 1,8-cineole was the main active component responsible for its antibacterial and antifungal properties [10], [11], [12], [13], [14].…”

The chemical composition of three cajuput essential oils of Melaleuca cajuputi (M. cajuputi) from different area in Indonesia were analyzed using gas chromatography-mass spectrometry to determine the similarities and differences among their volatile chemical compositions. These cajuput oils come from Malang (East Java), Buru Island (Maluku), and Merauke (Papua). It contains 30 components of which 26 components have been identified. Cajuput oils in this research contained significant quantities of 1,8-cineole (42-60%), α-terpineole (4-18%), caryophyllene (0.6-11%), and α-pinene (3-12%). Oil from Malang (East Java) also contained significant amounts of α-selinene (6.73 %) and accompanied by lesser amounts of sesquiterpene detected only in this oil: valencene, germacrene B, ledol, globulol, epiglobulol, and viridiflorol. The hemiterpene compound, 2,4pentanediol (11.44%), was only found in oil from Buru Island. Oil originating from Papua also contained α-gurjunene (17.31%) as the major component. Cajuput oil from Malang (East Java) has the highest number of chemical components than the others.
