“…This variation in the essential oil explains why some works show the antibacterial action of the essential oil, as Tesch et al [27], where the oil showed activity against E. coli ATCC 25922 (MIC 350 μL/mL), Klebsiella pneumoniae ATCC 23357 (MIC 300 μL/mL), Salmonella Typhi CDC57 (MIC 400 μL/mL). In this study, the natural product presented eucalyptol (C 10 H 18 O) and fenchone (C 10 H 16 O) as the main compounds.…”

Mesosphaerum suaveolens (Lamiaceae) is a medicinal plant commonly used in Brazil for the treatment of diseases related to the digestive tract and respiratory diseases, so we hypothesized that the essential oil of this species may have antibacterial activity. Thus, we aimed to evaluate the in vitro antibacterial and modulatory activity of the essential oil of M. suaveolens as well as to characterize its chemical composition. The identification of the constituents was performed by gas chromatography-flame ionization detector (GC-FID) and the antibacterial and modulating activity by the plate microdilution method. We found the oil had sesquiterpene β-caryophyllene as the major component. This compound may account for the antibacterial activity against Staphylococcus aureus strains, since the essential oil had a MIC of 64 μg/mL for the standard strain and 256 μg/mL for the multiresistant strain, demonstrated that the oil does not exhibit drug modulating activity. Thus, M. suaveolens oil has bioactive compounds which can be used in the preparation of drugs.

“…The antimicrobial activities of essential oils of some H. suaveolens species were reported previously. A notable observation was that the oils under investigation were ineffective against the strain of E. coli ATCC 25922 contrary to the data reported for Venezuela sample [22]. In addition, the oil samples displayed a lesser activity against S. aureus ATCC 25923 compared with sample from Benin Republic [25] tested for antimicrobial activity.…”

“…Previously, the composition of essential oil the aerial parts of H. suaveolens from Vietnam were eugenol (68.2%) and germacrene D (11.0%) were the major constituents of the oil [21]. The main constituents of essential oils obtained from the leaves and flowers of H. suaveolens collected from Venezuela [22] were 1,8-cineole (19.1% leaves, flowers 13.3%), fenchone (18.5% leaves, flowers 16.1%), bicyclogermacrene (12.7% leaves, flowers 18.8%), D-germacrene (6.3% leaves, flowers 10.0%). Another analysis reported the abundance of β-elemene (39.71%), γ-elemene (8.82%) and bicyclogermacrene (8.52%) in the essential oil of H. suaveolens [23].…”

“…[24], among others. The essential oil from Venezuela displayed antibacterial activity against Escherichia coli ATCC 25922, Klebsiella pneumoneae ATCC 23357, and Salmonella typhi CDC 57, with minimun inhibitory concentration (MIC) ranging between 300 μL/mL and 450 μL/mL (22). The essential oil from the leaves of H. suaveolens was effective on Staphylococcus aureus Meti-R and S. aureus ATCC 25923 with MIC values of 5.37 mg/mL [25].…”

Aims: This present study described the chemical constituents and antimicrobial activity of essential oils hydrodistiled from the leaves and flowers of Hyptis suaveolens (L.) Poit. Study Design: This research was designed to accommodate different stages such as collection of authentic sample of Hyptis suaveolens, obtain essential oil by hydrodistillation, chemical analysis of the oil samples by gas chromatography (GC) and gas chromatography coupled with mass spectrometry (GC/MS) and screening of the essential oils for antimicrobial activity. Place and Duration of Study: School of Natural Science, Vinh University, Vinh City, Nghệ An Province, Vietnam, between August and December 2018. Methodology: The leaves and flowers of H. suaveolens used for this study were gotten from Đồng Văn Commune, Pù Hoạt Nature Reserve, Vietnam. The collection was done in December 2018. Essential oils were distilled off using hydrodistillation method according to established procedure. The determination of antimicrobial efficacy of essential oils of H. suaveolens will be achieved by the method of microdilution broth susceptibility assay. The minimum inhibitory concentration (MIC) and IC50 were evaluated accordingly. Results: The major compounds in the oil were b-caryophyllene (31.1% and 33.7%), caryophyllene oxide (17.6% and 3.9%), phytol (9.9% and 2.7%) and a-humulene (6.7% and 6.6%), respectively. The leaf oil displayed strong antimicrobial activity against Enterococcus faecalis ATCC299212, Bacillus cereus ATCC14579 and Candida albicans ATCC10231 with minimum inhibitory concentrations (MIC) of 16.0, 32.0 and 16.0 µg/mL respectively, while the IC50 values were 5.78, 9.35 and 6.78 µg/mL, respectively. The flower oil showed activity towards the same organisms with MIC values of 64.0, 64.0 and 16.0 µg/mL, respectively; with IC50 values of 20.45, 26.78 and 6.78 µg/mL, respectively. Both essential oils exhibited moderate activity towards Staphylococcus aureus ATCC25923 with MIC of 256.0 µg/mL. Conclusion: The results are indication of the potential of H. suaveolens essential oils as source of antimicrobial agents.

“…Plants of this genus are covered with glandular trichomes that produce essential oils that make them very popular in rural areas of Latin America where they are taken as an infusion to treat respiratory and gastrointestinal disorders or skin diseases [3,4]. Different pharmacological activities (antibacterial [5,6] anti-inflammatory [7], antiparasitic [8], and antiproliferative [9]) have been tested experimentally in this genus, so it is an interesting taxon in the field of medical applications. Some Hyptis have been used against malaria ( Hyptis mutabilis (Rich.)…”

In rural areas of Latin America, Hyptis infusions are very popular. Hyptis obtusiflora extends from Mexico throughout Central America to Bolivia and Peru. It has added value in Ecuador where it has been used by different ethnic groups. We aimed to learn about the traditional knowledge of ancient Kichwa cultures about this plant, and to contrast this knowledge with the published information organized in occidental databases. We proposed to use traditional knowledge as a source of innovation for social development. Our specific objectives were to catalogue the uses of H. obtusiflora in the community, to prospect on the bibliography on a possible chemical justification for its medicinal use, to propose new products for development, and to give arguments for biodiversity conservation. An ethnobotanical survey was made and a Prisma 2009 Flow Diagram was then followed for scientific validation. We rescued data that are novel contributions for the ethnobotany at the national level. The catalogued main activity of anti-inflammation can be related to the terpene composition and the inhibition of xanthine oxidase. This opens the possibility of researching the extract of this plant as an alternative to allopurinol or uricosuric drugs. This is a concrete example of an argument for biodiversity conservation.
