  • The effectiveness of Palmarosa, Neroli and Jasmin blending oil on dry skin of rat induced by kitchen detergent are investigated. The experimental groups were divided the control group, group treated with surfactant, group treated with Palmarosa and Neroli, and group with Palmarosa, Neroli and Jasmin. Observation of epidermis and the alteration of mast cell were performed with photomicroscope. According to the epidermis morphological changes analysis, the A3 group treated with Palmarosa, Neroli and Jasmin blending oil was appeared the most similar with the control group, and the A2 group applied with Palmarosa and Neroli blending oil was sequently displayed similar characteristics. The collagen layer's breakaway resulting from Palmarosa essential oil, the collagen layer's restoration resulting from Neroli essential oil, the collagen layer's retention hyperkeratosis resulting from Jasmin essential oil were observed in the structure of the epidermal layer. In photomicrosope observation of mast cell to examine the inflammatory reactions, the increase in size and number of mast cell were showed in A1 group treated with surfactant compared to the control group. The number of mast cells definitely decreased in groups which were treated with Palmarosa, Neroli and Jasmin blending oil.

  • The objective of this study was to find herbicidal compounds in the essential oil of palmarosa (Cymbopogon martini). Of essential oils from basil (Ocimum basilicum), blackpepper (Piper nigrum), clary sage (Salvia sclarea), ginger (Zingiber pfficinale), hyssop (Hyssopus officinalis), nutmag (Myristica fragrance), palmarosa (Cymbopogon martini), fennel (Foeniculum vulgare), sage (Salvia leucantha), and spearmint (Mentha spicta), the herbicidal activity of palmarosa essential oil, which was determined by a seed bioassay using rapeseed (Brassica napus L.), was highest ($GR_{50}$ value, $201{\mu}g\;mL^{-1}$). In palmarosa essential oil, 11 volatile organic chemicals were identified by gas chromatography-mass spectometry with solid-phase micro-extraction apparatus and the major constituents were geraniol (40.23%), geraniol acetate (15.57%), cis-ocimene (10.79%), and beta-caryophyllene (8.72%). The $GR_{50}$ values of geraniol, citral, nerol, and geranyl acetate were 151, 224, 452, and $1,214{\mu}g\;mL^{-1}$, respectively. In greenhouse and field experiments, foliar application of palmarosa essential oil at the level of $80kg\;ha^{-1}$ controlled weeds effectively. Overall results of this study showed that the herbicidal activity of palmarosa essential oil could be due to geraniol and citral which had lower $GR_{50}$ values.

  • The effectiveness of Palmarosa and Neroli essential oil on dry skin of rat induced by kitchen detergent are investigated. The experimental groups were divided the control group (C), group treated with surfactant (A1), group treated with Palmarosa (A2), group treated with Neroli (A3), group treated with Palmarosa and Neroli (A4). The protein analysis of all experimental groups was performed with SDS polyacrylamide gel electrophoresis and observation of epidermis and the alteration of mast cell were performed with photomicroscope. According to the protein analysis, the A3 group treated with Neroli essential oil was appeared the most similar with the control group. And then the A4 group treated with Palmarosa + Neroli essential oil was appeared the most similar with the control group. According to the results of morphologic view with keratin layer, the keratin layer's breakaway resulting from Palmarosa essential oil, the keratin layer's restoration resulting from Neroli essential oil was appeared. And then the structure of the epidermal layer was preserved by hyperkeratosis reaction. In photomicrosopic obersevation of mast cell to examine the inflammatory reactions, the increase in size and number of mast cell were showed in A1 group treated with surfactant compared to the control group (C). The number of mast cells definitely decreased in groups (A3, A4) which were treated with Neroli essential oil.

  • Purpose: In this paper, we show our blending ratio of 10 types of Essential Oils that survives beneficial bacteria and kills harmful bacteria in the scalp, and we investigate the possibility of application of our blending ratio to the development of anti-dandruff products and the possibility of being used as a raw material for clinical beauty and customized cosmetics. Methods: The scalp microorganisms used in our study were M. furfur, S. epidermidis, E. coli, and P. nitroreducens. There are a total of 10 Essential Oils such as True Lavender, Lime, Roman chamomile, Rosemary camphor, Cedarwood, Geranium, Clove, Tea tree, Palmalosa, and Peppermint. The antibacterial test of the blended Essential Oil was carried out according to the test method of the standardized evaluation methodology of "Food and Food Additives Code". Since M. furfur is related to the growth of sebum in the scalp, in this study we used the fnLNB and the fnLNA with 20 ㎖ of whole fat cow milk added. Results: The blending ratio of EO, which inhibits dandruff-causing bacteria such as M. furfur, S. epidermidis, E. coli, and does not inhibit P. nitroreducens showing dominant growth in a healthy scalp, was B8(Clove 0.2%, Roman chamomile 0.5%, Tea tree 0.3%), B9(Geranium 0.1%, Palmarosa 0.1%, Roman chamomile 0.5%, Tea tree 0.3%), B10(Clove 0.1%, Geranium 0.1%, Palmarosa 0.1%, Roman chamomile 0.5%, Tea tree 0.2%). Conclusion: It is thought that the blending ratio of BEO obtained as a result of this study can provide a basis for use as an alternative to antibiotics in developing anti-dandruff drugs and emerge as a new alternative to solve scalp microbial imbalance. In order for EO to be used as a useful raw material for anti-dandruff preparation, researches on 1) Standardization (the effects of products differ according to the types, regions, climate, extraction methods, etc.), 2) Antimicrobial effects, 3) Safety, etc., must be established.

  • The present study aimed to evaluate the phytotoxic potential of essential oils. For this purpose, 18 essential oil samples extracted from Korean plants and 64 commercial essential oils were screened for their phytotoxic potential against the seedling growth of Brassica napus L. (rapeseed). Among the 82 samples, 11 commercial oils (cinnamon, citronella, clove, cumin seed, geranium, jasmine, lemongrass, palmarosa, pimento, rose otto and spearmint) strongly inhibited the seedling growth with $GR_{50}$ value < $150{\mu}g\;mL^{-1}$. Major components from these effective essential oils were identified by solid phase microextraction/gas chromatography-mass spectrometry (SPME/GC-MS). GC-MS analyses revealed that the effective samples mainly consist of benzyl benzoate, carvone, citral, citronellol, eugenol, geraniol, D-limonene and terpinene. Subsequently, bioactivity of these individual components was evaluated against the seedling growth of B. napus, Echinochloa crus-galli and Aeschynomene indica. The components from different chemical groups exhibited different potency in inhibiting the seedling growth with varied $GR_{50}$ values ranged from $29{\mu}g\;mL^{-1}$ to > $1000{\mu}g\;mL^{-1}$. In the greenhouse experiment, citral and geraniol completely suppressed the growth of all the tested 10 plants at $100kg\;ha^{-1}$. In conclusion, the individual essential oil components geraniol and citral could be used as natural herbicides for weed management.

  • Although various studies have focused on the relationship between essential oils (EOs) and skin flora, there are only few comparative studies on the antibacterial properties of EOs and their efficacy against common microorganisms. In this study, we tested the antibacterial activity of 10 different EOs against Staphylococcus epidermidis(S. epidermidis) with oxacillin as control. Optical density was used to measure the activity of solutions containing the EOs and S. epidermidis at two different concentrations. Three EOs (palmarosa, lemongrass, and Mellissa True) had higher antibacterial activity than oxacillin, but their concentrations had negligible effect on antibacterial activity.
