  • Effects of wood vinegar on the activity of various insecticides were determined by measuring the mortality of two species of rice planthoppers, Nilaparvata lugens and Laodelphax striatellus. Wood vinegar itself did not show insecticidal activity on planthoppers. When the planthoppers were treated with wood vinegar mixed with one of insecticides such as BPMC, dinotefuran, imidacloprid, carbosulfan or insect growth regulators, the planthopper mortality induced by carbosulfan was greatly increased by the wood vinegar in comparison with a single carbosulfan treatment. Wood vinegar showed no effect on other insecticides. In addition, the wood vinegar-carbosulfan mixture significantly reduced AChE activity of planthoppers, which is a target molecule of carbosulfan. This result suggests that wood vinegar has a synergistic effect on the insecticidal activity of carbosulfan. Our study provides information on a potential role of wood vinegar in facilitation of activity of specific insecticides.

  • The study was conducted to determine whether oak wood vinegar extract influences blood alcohol concentration and hangover syndrome in healthy volunteers. 2% wood vinegar extract was effective to inhibit increase of blood alcohol concentration after alcohol intake and showed significantly different (P<0.1) compared to placebo. By result of questionnaire of volunteers, wood vinegar extract showed effects improving hangover syndrome. In comparative study about blood alcohol concentration and hangover syndrome of wood vinegar extract and other extract that hangover improvement effect was reported, average maximum blood alcohol concentration was lowered in those taking wood vinegar extract than those taking other extract. At drinking completion 210minutes (T210), blood alcohol concentration of those taking wood vinegar extract was the lowest by 0.063% compared with other extract but was not significantly different between in those taking wood vinegar extract and in those taking other extract. However, wood vinegar extract's experimental group was the highest by 0.462 in decrement rate of blood alcohol concentration and, when did P<0.1 by significance level, indicated difference that mean statistically compared to placebo group uniquely. At those taking wood vinegar extract, the improvement rate and the aggravation rate of hangover syndrome was each 87%, 2%. Thus it was concluded that wood vinegar extract showed excellent alcohol oxidation and was effective in hangover improvement.

  • The chemical properties of oak tree wood vinegar and the effect of wood vinegar on the tomato seedling were investigated to apply wood vinegar efficiently to the organic - and natural farming system. On the basis of the results from chemical properties of the oak tree wood vinegar, mineral nutrient contents of wood vinegar was low. Therefore, wood vinegar could not be a suitable nutrient source for the plant growth at 500∼1000 times dilution level. which commonly used in the farming, if only wood vinegar is supplied for the nutrient source for the plant growth. The application of wood vinegar increased root growth up the 500 times dilution level while decreased shoot growth. Furthermore. the anion concentrations such as nitrate and phosphate of the plant were decreased by the application of wood vinegar while cation concentrations such as K. Ca. and Mg were increased. Phenolic compounds of wood vinegar such as chlorogenic acid and ferulic acid enhanced the root growth. Interestingly the application of ferulic acid increased both root and shoot growth at the level of 10$^{-4}$ M concentration. It indicated that the effect of wood vinegar on the production of healthy plant seedling may be due to the beneficial root growth by phenolic compounds such as chlorogenic acid and/or ferulic acid of the wood vinegar. However. the effect of the wood vinegar on the plant growth could be influenced by synergism or antagonism of different phenolic compounds in wood vinegar used. In addition. drench in the soil of wood vinegar may be more beneficial compared to foliar application for the improvement of root activity and plant growth.

  • The purpose of this study was to investigate the nitrite scavenging, eletron donating activity and antioxidant activity of wood vinegar on soybean oil. Wood vinegar was added to soybean oil in the quantities of 0.5, 1 and 5%. Nitrite scavenging effect of all concentrations diminished at higher pH, while in the case of pH 1.2, it showed a nitrite scavenging effect of more than 80% at concentration above of 100 ㎕/mL. The electron donating activity was about 80% at concentration above of 50 ㎕/mL. Soybean oil without the addition of wood vinegar was used as a control. The oxidation of these samples was determined by measuring the peroxide value(POV), thiobarbituric acid(TBA) value and acid value(AV). When wood vinegar was added 1 and 5%, the peroxide value wag lower than both the control and 0.1% BHT. TBA value were in the 5% wood vinegar tallowed by 1% wood vinegar, 0.1% BHT, 0.5% wood vinegar and the control, respectively. The results showed that the acid values were lowest in 5% wood vinegar, followed by the 0.1% BHT, 1% wood vinegar, 0.5% wood vinegar and finally the control.

  • Two experiments were conducted to investigate the feeding value of wood vinegar in weanling pigs. In Experiment 1, weanling pigs (n = 224; Landrace ${\times}$Yorkshire ${\times}$Duroc, 21${\pm}$3 d-old, initial BW 6.12${\pm}$0.10 kg) were assigned to four dietary treatments. Different levels of wood vinegar were added to the diets as dietary treatments (0, 0.1, 0.2 and 0.3%). Each treatment comprised 4 replicates with 14 piglets in each. Experimental feeding was conducted for 28 d in two phases (phase I, d 0 to 14 and phase II, d 15 to 28). Feeding of wood vinegar linearly (p<0.05) improved the phase I, phase II and overall ADG and increased (linear, p<0.05) the overall and phase II ADFI. Linear improvements in the apparent fecal digestibility of dry matter (p = 0.013), gross energy (p = 0.019) and crude protein (p = 0.033) were observed as the level of wood vinegar was increased in the diet of pigs. Experiment 2 was conducted to compare dietary wood vinegar with commonly used growth promoters, organic acid (mixture of 21% phosphoric acid, 3.25% propionic acid, 2.8% formic acid, 10% calcium formate and 5% calcium propionate) and antibiotic (aparamycin). A total of 288 weanling piglets (Landrace ${\times}$Yorkshire ${\times}$Duroc, 22${\pm}$2 d-old, initial BW 6.62${\pm}$0.31 kg) were assigned to four treatments with four replicates (18 piglets/pen) for 28 days and fed in 2 phases: phase I, d 0 to 14 and phase II, d 15 to 28. The dietary treatments were control (corn-soybean meal basal diet without antibiotics) and diets containing 0.2% antibiotic, 0.2% organic acid and 0.2% wood vinegar. Pigs fed antibiotic showed higher (p<0.001) ADG and better feed efficiency followed by pigs fed wood vinegar and organic acid diets while those fed the control diet had lowest ADG and poorest feed efficiency. The overall and phase I ADFI was highest (p<0.001) in pigs fed wood vinegar and lowest in pigs fed the control diet. Apparent fecal digestibility of dry matter, gross energy and crude protein was significantly higher (p<0.05) in pigs fed the antibiotic diet when compared with pigs fed the control but comparable among pigs fed antibiotic, organic acid and wood vinegar diets. Higher populations of Lactobacillus (p = 0.004) were noted in the ileum of pigs fed the wood vinegar diet, while the population of coliforms in the ileum and cecum was higher (p<0.001) in pigs fed the control diet when compared with pigs fed antibiotic, organic acid or wood vinegar diets. These results indicated that wood vinegar could improve the performance of weanling pigs by improving the nutrient digestibility and reducing harmful intestinal coliforms; moreover performance of pigs fed wood vinegar was superior to those fed organic acid.

  • This study was carried out to investigate the effects of wood vinegar on growth and resistance of peppers. It was observed that heights and dried weights of the peppers treated with diluted wood vinegar were increased, especially 1:500 diluted wood vinegar was the most effective. The Wood vinegar also showed antibacterial activity against Xanthomonas axonopodis pv. vesicatoria directly. The growth of X. axonopodis pv. vesicatoria was completely inhibited when incubated for 12 hours at $30^{\circ}C$ with non diluted wood vinegar. The peppers applied wood vinegar did not show induced systemic resistance after injecting X. axonopodis pv. vesicatoria.

  • Component analysis and physico-chemical properties of wood and rice hull vinegars were conducted in order to promote the utilization of these environment-friendly materials. Results showed that wood vinegar had higher specific gravity (2.5) and tar content (0.3%), but lower acid content (1.0%) than rice hull vinegar (1.7, 0.05% and 4.4%, respectively). GC-MS component analysis revealed that rice vinegar had higher phenol content (34%) than wood vinegar (11.49%). Acetic acid and propionic acid were also higher in rice hull vinegar. On the contrary, wood vinegar had higher Furancarboxyl aldehyde content (41.6%) than rice hull vinegar (0.67%). Thus, different results in DPPH radical electron donating-abilities were obtained due to different percent composition of each vinegar.

  • Termiticidal and fungicidal activities of wood vinegar from Cinnamomum parthenoxylon (CP) stem wood have been evaluated against Coptotermes curvignathus and wood rotting fungi (Schizophyllum commune and Fomitopsis palustris). The utilized CP wood vinegar was produced in the operating temperature range 250-300℃ pyrolysis. A no-choice test was applied for evaluating termiticidal activity with 33 active termites and antifungal activity using the agar media assay. The result showed that an increase in the concentrations of CP wood vinegar significantly raised the mortality of termite. CP wood vinegar showed high termiticidal activity, organic acids (acetic acid 42.91%, 3-butenoic acid 6.89%, butanoic acid, 2-propenyl ester 2.26%), and ketones (1-hydroxy-2-propanone 5.14%, 3-methylcyclopentane-1,2-dione 2.34%) might be largely contributed to termiticidal activity in addition to other minor components. Furthermore, CP wood vinegar exhibited significant inhibition of fungal growth. These data showed that CP wood vinegar was more toxic to white-rot fungi (S. commune) than brown-rot (F. palustris). The results suggested that phenolic compounds from lignin degradation were responsible for good antifungal activity.

  • Wood vinegar is well known as a softening agent affecting on the stratum corneum that is easy to penetrate into the skin. In this study, we prepared mixed ursolic acid hydrogel with wood vinegar(1, 2, 5%) as a penetration enhancer. The accumulation of ursolic acid in the skin from hydrogels was evaluated in vitro hairless mouse skin and skin moisturizing effect of them was evaluated using the corneometer and the tewermeter. And the role of stratum corneum as a protective barrier was evaluated as well. The hydrogels were retained about 40% of water retention capacity 2hrs and had better effect on the stripped skin than full-thickness skin. The accumulation of ursolic acid through stripped skin from hydrogels with wood vinegar was not change compared to normal skin, which indicated the action site of wood vinegar and the accumulation site of ursolic acid would be stratum corneum. From these result, we could find wood vinegar seems to be a good enhancer for active materials with anti-wrinkle and anti aging effect such as ursolic acid, and can be a developed topical delivery system maintaining excellent water retention capacity.

  • The concerns of wood vinegar increase with its various applications to food additive, functional drink, and in the sustainable farming. Chaff vinegar, a by-product of chaff charcoal which is produced by distilling smoke and having similar ingredients and efficacy with wood vinegar, contains harmful tar in the acceptable range and can be mass-produced. A chaff vinegar distiller, commercially mass-productive, was developed using a water cooling system. Initially distilled vinegar by the developed system contained little harmful tar in the acceptable range for the agricultural use and its acidity was about pH 3.2. Treatment of the chaff vinegar in the enhancing emergence test showed greater number of emerged seedlings, and vise-versa. Treatment of diluted in 100-holds showed 44.0% of emerged and 8.6% of not-emerged seedlings.
