Clove (Syzygium aromaticum) is a popular medicinal plant which has been traditionally used in India as spice and medicine to counter various ailments. However, the stress modulatory and antiaging potential of this plant is yet to be characterized. Therefore, the present study evaluates the effect of clove oil (CO) on oxidative stress, lifespan, mobility, and the expression of aging-related prot...

To investigate the antibacterial functionality of natural colorant extracts, five kinds of natural dying aqueous solutions were obtained by extraction from peony, pomegranate, clove, Coptis chinensis and gallnut using water at 90 °C for 90 min with a liquor ratio (solid natural colorant material/water, weight ratio) of 1:10. The colorimetric assay and antibacterial activity of cotton, silk, and...

Antifungal activities of clove essential oil and its volatile vapour against dermatophytic fungi including Candida albicans, Epidermophyton floccosum. Microsporum audouinii, Trichophyton mentagrophytes, and Trichophyton rubrum were investigated. Both clove essential oil and its volatile vapour strongly inhibit spore germination and mycelial growth of the dermatophytic fungi tested. The volatile...

The genus Celoporthe was first described when C. dispersa was discovered in South Africa associated with dieback and cankers on trees in the Myrtales. Four additional species were recently described from Eucalyptus and Syzygium cumini in China as well as S. aromaticum and Eucalyptus in Indonesia. Inoculation trials have shown that all Celoporthe species, including those that have not been found...

Quorum sensing controls the virulence determinants in most proteobacteria. In this work, the hexane, chloroform and methanol extracts of an Ayurveda spice, namely clove (Syzygium aromaticum), shown anti-quorum sensing activity. Hexane and methanol extracts of clove inhibited the response of C. violaceum CV026 to exogenously supplied N-hexanoylhomoserine lactone, in turn preventing violacein pro...

This study focused on the development of gelatin-based films with incorporation of microcrystalline cellulose as reinforcement material. Clove (Syzygium aromaticum), nutmeg (Myristica fragrans), and black pepper (Piper nigrum) oleoresins containing antimicrobial compounds of natural origin were incorporated into the films. The mechanical, thermal, optical, and structural properties, as well as ...

To examine the effect of biflorin, a component of Syzygium aromaticum, on memory deficit, we introduced a scopolamine-induced cognitive deficit mouse model. A single administration of biflorin increased latency time in the passive avoidance task, ameliorated alternation behavior in the Y-maze, and increased exploration time in the Morris water maze task, indicating the improvement of cognitive ...

Sixteen volatile compounds were identified from the n-hexane extract of the buds of Syzygium aromaticum by using gas chromatography-mass spectroscopy (GC-MS). The major components were eugenol (71.56 %) and eugenol acetate (8.99 %). The dichloromethane extract of the buds yielded limonin and ferulic aldehyde, along with eugenol. The flavonoids tamarixetin 3-O-b-D-glucopyranoside, ombuin 3-O-b-D...

Essential oils of sixteen Chinese medicinal plants were screened for fumigant toxicity against Bemisia tabaci. The essential oil of Allium sativum exhibited the strongest fumigant activity against B. tabaci with an LC50 value of 0.11 μg/l followed by the essential oils of Agastache rugosa (LC50 = 7.08 μg/l), Illicium verum (LC50 = 8.61 μg/l), Chenopodium ambrosioides (LC50 = 8.80 μg/l), and Syz...

The essential oils extracted from the four herbs, cinnamon (Cinnamomum verum), clove (Syzygium aromaticum), ginger (Zingiber officinale) and holy basil (Ocimum sanctum), were investigated for their antimicrobial activity and mode of action against Lactococcus garvieae, a fish pathogenic bacteria causing lactococcosis. Of all the tested oils, clove oil had the strongest inhibitory effect and exh...
