A useful species identification and quality control using volatile patterns of ssajuari-ssuk and sajabal-ssuk (Artemisia princeps Pamp. cv. ssajuari and Artemisia princeps Pamp. cv. sajabal; Korean mugwort) according to air-drying term by fast gas chromatography with uncoated surface acoustic wave sensor.

Ssajuari-ssuk and sajabal-ssuk have many clinical benefits. It is difficult to discriminate between these two species based on general characteristics aside from the shapes of the leaves. Thus, species identification and quality control between ssajuari-ssuk and sajabal-ssuk are of great concern in plant science and clinical therapy. The aim of this study is to determine whether fast gas chromatography with uncoated surface acoustic wave sensor (GC-SAW) can be a useful technique for performing species identification and quality control using volatile patterns of ssajuari-ssuk and sajabal-ssuk air-dried for 4months and 2years and 4months. Fast GC-SAW sensor provides second unit analysis, simple, on-line measurements that do not require pretreatment of the sample and rapid sensory information. Headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS) was employed to confirm the identification of the volatiles and compared to fast GC-SAW sensor. In air-dried sajabal-ssuk, the concentration of 1,8-cineole was higher than that in air-dried ssajuari-ssuk, while the level of α-thujone was considerably lower than that of air-dried ssajuari-ssuk. Each of ssajuari-ssuk and sajabal-ssuk air-dried for 4months and 2years and 4months has its own characteristic volatile pattern owing to its individual chemotypes or chemical compositions. Consequently, the fast GC-SAW sensor can be a useful technique for species identification and quality control using volatile patterns of ssajuari-ssuk and sajabal-ssuk air-dried for 4months and 2years and 4months. This method can be used for the standardisation of quality control using volatile patterns of herbal medicines.

A useful quality control using herbal volatiles of Artemisia princeps Pamp. cv. ssajuari (ssajuari-ssuk; Korean mugwort) according to air-drying time by fast gas chromatography with uncoated surface acoustic wave sensor (Electronic zNose).

Korean mugwort has been used as a traditional medicine. Specifically, air-dried Artemisia princeps Pamp. cv. ssajuari (ssajuari-ssuk; Korean mugwort) has been used as moxa in moxibustion therapy. Thus, the evaluation of high quality ssajuari-ssuk containing herbal volatiles is of great interest in clinical therapy and the food industry. The aim of this study is to determine whether fast gas chromatography with uncoated surface acoustic wave (fast GC/SAW) sensor can be a useful technique for performing quality control using herbal volatiles of ssajuari-ssuk air-dried for different times. Fast GC/SAW sensor, called "Electronic zNose", is also a headspace sampling method and is an effective simple analytical method with a second unit analysis providing on-line measurements without the need for pretreatment of the sample. Headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS) was employed to confirm the identification of the volatiles and compared to fast GC/SAW sensor. Artemisia princeps Pamp. cv. ssajuari air-dried for 2 years and 4 months (the third year), containing the highest total amount of herbal volatiles, was superior to the others (the first year, the second year, the fourth year) in quality. Moreover, fast GC/SAW sensor shows a high repeatability (relative standard deviation 0.77%∼6.23%), excellent sensitivity (limit of detection value of 0.47pg/mL), and good linearity (correlation coefficient r2 = 0.997) over the range of nanogram for α-thujone. Therefore, the fast GC/SAW sensor can be a useful analytical method for the discrimination and quality control of volatiles of herbal and medicinal plants according to air-drying time, as it provides a simple and second unit analysis.

Vegetation community composition along disturbance gradients of four typical open‐pit mines in Yunnan Province of southwest China

AbstractOpen‐pit mining causes severe land degradation in Yunnan Province, Southwest China. Vegetation restoration on the degraded land with open‐pit mining is challenging due to great physical and chemical condition changes of the post‐mined landscape. In this study, we compared the vegetation community composition and environmental factors along three disturbance gradients (mining area, restoration area, and control area) in four typical open‐pit mine types (phosphate, zinc, tin, and iron sites). Nonmetric multidimensional scaling analysis revealed that there are significant differences in the vegetation communities along three gradients for these mine sites. Quality species were selected by indicator species analysis for vegetation restoration as follows: Chloris virgata Sw. and Artemisia princeps Pamp at the phosphate site; Coriaria nepalensis Wall., Artemisia princeps Pamp, and Picris hieracioides L. at the zinc site; Artemisia princeps Pamp at the tin site; and Panicum brevifolium L. at the iron site. Canonical Correspondence Analysis ordination and Monte Carlo permutation tests were further used to determine the effects of environmental factors on vegetation diversity. The results showed that Cd, As, Zn, Pb, TC, and altitude all had significant effects on vegetation diversity (P < 0.05). Additionally, we found that the integrated effects of these variables on vegetation were greater in the mining area than in the other two gradients based on the model with the lowest Akaike Information Criterion. These results suggest that any plans for vegetation restoration in open‐pit mining areas should take disturbance intensity, mine types, and critical environmental variables into account.

Analysis of Lutein in Mugwort (Artemisia princeps Pamp.) Paste and Evaluation of Manufacturing Processes.

Lutein, a type of xanthophyll, possesses antioxidative properties that contribute to the prevention of various diseases. Preliminary screening has shown that Japanese mugwort (Artemisia princeps Pamp.) contains high amounts of lutein. In this study, we evaluated the lutein concentration in a processed mugwort product (mugwort paste). By using high-performance liquid chromatography coupled with visible light detection or mass spectrometry, the lutein concentration in mugwort paste was determined as 38 mg/100 g dry weight, which indicates that mugwort is a potentially valuable natural food source of lutein. We also investigated the effects of the manufacturing process and found that the lutein content was significantly increased by the boiling and dehydrating processes during the production of mugwort paste. Mugwort paste that is rich in lutein may therefore serve as an effective nutraceutical.

Developmental Changes of the Photochemical Reflectance Index (PRI), Chlorophyll Fluorescence and Leaf Pigments Show the Adaptability of Trees to Local Environments

For plants growing in parks and along the roadsides of a city, the environmental and seasonal regulation of growth, or photosynthesis, is seldom assessed. The phenology of plants may differ due to varying environments, which may result in different growth or adaptability to local environments. Therefore, we explored several assays and optical indicators of photosynthesis and stress in three tree species (Prunus yedoensis Matsum, Zelkova serrata Makino and Acer palmatum Thunb. ) and two herbaceous species (Artemisia princeps Pamp and Taraxacum officinale Weber)growing commonly in three local parks of Changwon city, a large industrial city in Korea. The photochemical reflectance index (PRI), chlorophyll fluorescence, and pigments including chlorophyll and the flavonoids of leaves were monitored over a growing season for two years to evaluate the adaptability of plants to local environments. The values of all measurements exhibited striking seasonal and regional changes. PRI values were closely timed with photosynthetic activity and the pigment formation of leaves, particularly in some tree species. For the tree species, the plants which had the low values of PRI during the active growing season showed low levels of both chlorophyll fluorescence and high level of flavonoid, indicating that these plants were experiencing low photosynthetic activity and the specific needs in growth and development were not sufficiently provided by the local environment. Our results indicate that PRI provided a clear optical indicator of plant adaptability to the local environment and may provide a useful metric of effective growth using remote sensing measurements. Furthermore, the periodic PRI measurement is encouraged to be included in the surveillance program for city plant management.

The combination of Artemisia princeps Pamp, Leonurus japonicas Houtt, and Gardenia jasminoides Ellis fruit attenuates the exacerbation of energy, lipid, and glucose by increasing hepatic PGC-1α expression in estrogen-deficient rats.

BackgroundArtemisia princeps Pamp (APP), Leonurus japonicas Houtt (LJH), and Gardenia jasminoides Ellis fruit (GJE) have been traditionally used in East Asia to treat women’s diseases related to reproductive system. They may attenuate the deterioration of energy, lipid, glucose and bone metabolism by estrogen deficiency. The present study explored the combination of APP, LJH, and GJE to overcome the symptoms of estrogen deficiency and the mechanism was explored.MethodsOvariectomized (OVX) rats were divided into five groups and fed high-fat diets supplemented with 2 % dextrin (control), 2 % APP, 2 % APP + LJH (15:5), APP + LJH + GJE (10:5:5) or 17β-estradiol (30 μg/kg bw/day) for 8 weeks. After 8 weeks of their consumption, energy, lipid, glucose and bone metabolisms were investigated and hepatic insulin signaling and fatty acid metabolism were determined.ResultsAPP + LJH + GJE, but not APP itself, improved energy metabolism and attenuated a decrease in energy expenditure by the same amount as estrogen. Moreover, APP + LJH + GJE reduced visceral fat and intramuscular fat and increased lean body mass measured by DEXA by as much as the positive-control. APP itself suppressed increased LDL cholesterol and triglyceride levels in OVX rats and APP + LJH + GJE alleviated dyslipidemia in OVX rats. Overnight-fasted serum insulin levels and HOMA-IR were reduced in the descending order of APP, APP + LJH, APP + LJH + GJE, positive-control in OVX rats. APP and APP + LJH elevated insulin secretion in the 1st part of OGTT to decrease serum glucose levels while APP + LJH + GJE reduced serum glucose levels without increasing serum insulin levels during OGTT. APP + LJH + GJE decreased insulin resistance during ITT in OVX rats more than the positive-control. The APP + LJH + GJE group exhibited increased hepatic peroxisomal proliferator-activated receptor-γ coactivator-1α expression, which increased the number of genes involved in fatty acid oxidation and decreased fatty acid synthesis. Hepatic insulin signaling (pAkt and pGSK-1β) was also potentiated to reduce phosphoenolpyruvate carboxykinase proteins.ConclusionThe combination of APP + LJH + GJE attenuated various menopausal symptoms in OVX rats. Thus, it may have potential as a therapeutic agent for the treatment of postmenopausal symptoms.

Identification of bitter components from Artemisia princeps Pamp.

Identification of bitter components from the aerial parts of Artemisia princeps Pamp. was performed to search for a method to eliminate the bitter taste from A. princeps products. The aerial parts of A. princeps were extracted in an aqueous EtOH solution, and the obtained extracts were partitioned into essential-oil, flavonoid-rich, n-BuOH, and aqueous fractions. Two purified bitter sesquiterpenoids were identified through repeated column chromatography of the bitterest fraction, the flavonoid-rich fraction, through an activity-guided fractionation method. The compounds were identified to be 1α,6α,8α-trihydroxy-5α,7βH-guaia-3,9,11(13)-trien-12-oic acid and artecalin, respectively, based on the interpretation of NMR, MS, and IR spectroscopic data. Both compounds were 50 times bitterer than caffeine and had similar bitterness to quinine HCl. Neither eupatilin nor jaceosidin, the major active components of A. princeps, showed any bitterness.

Antioxidant Activities of Methanol Extracts from Selected Taiwanese Herbaceous Plants

The purpose of this study was to evaluate the total phenolic and flavonoid contents in acid methanol extracts of 19 plant species grown and used in Taiwan. The antioxidant activity of leafy plant extracts was determined by measuring the trolox equivalent antioxidant capacity (TEAC), oxygen radical absorption capacity (ORAC), and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. Polyphenol, flavonol, and flavonoid levels were high in Sonchus oleraceus (SO), Ohwia caudate Thunb. Ohashi (OC), Foeniculum vulgare Mill. (FV), and Artemisia princeps Pamp. var. orientalis (Pamp.) Hars. (ArP, fresh) as compared to the rest of tested plants. In addition, quercetin, myricetin, and morin were abundant in Dendranthe mamori folium (Ramat.) Tzvelev. (DM, dry), FV, SO, Alternanthera philoxeroides (Moq.) Griseb. (AlP), ArP (fresh) and Lonicera japonica Thunb. (LJ). Higher levels of the TEAC, ORAC, and DPPH radical scavenger were generated from extracts of OC, SO, DM (dry), and ArP (fresh). Significant and positive correlations among antioxidant activity and polyphenols and anthocyanidins were observed. ORAC values were also correlated with quercitin and morin. Therefore, these phytochemicals were some of the main components responsible for the antioxidant efficacy of tested plants.

Evaluation of the antioxidant effect of ganghwayakssuk (Artemisia princeps Pamp.) extract alone and in combination with ascorbic acid in raw chicken patties

We investigated the inhibition of lipid oxidation of raw chicken patties by the antioxidants ascorbic acid (Aa), ganghwayakssuk extracts (GE), and their combination (Aa + GE). All antioxidant combinations were effective at delaying lipid oxidation compared with the control or Aa. A combination of Aa + GE (0.05% Aa + 0.2% GE) was the most effective for delaying lipid oxidation (TBA reactive substances, conjugated dienes, and peroxide formation). The color values of all samples were significantly affected by adding GE. Additionally, the redness, color difference, and hue values of all treatments, except for Aa, were lower than those of the control as the amount of GE increased. The total viable bacterial counts of samples with GE 0.2 and Aa + GE 0.2 were significantly affected during storage (P < 0.05). The results suggest that adding an antioxidant combination reduced the oxidative stress and microbial growth of raw chicken patties stored for 12 d under normal refrigeration temperature, which may extend the shelf life of chicken patties.

Antioxidant action of ganghwayakssuk (Artemisia princeps Pamp.) in combination with ascorbic acid to increase the shelf life in raw and deep fried chicken nuggets

Raw and deep fried chicken nuggets containing various levels of ganghwayakssuk ethanolic extract (GE) in combination with ascorbic acid (Aa) were evaluated for shelf-life during refrigerated storage (4°C). The pH and color (lightness, redness, and yellowness) values of raw and deep fried samples were significantly affected by the addition of GE (P<0.05). All antioxidant combinations except for Aa+GE 0.01 were effective at delaying lipid oxidation (CD, POV, and TBARS) when compared to the control or Aa. Raw samples with GE 0.2 and Aa+GE 0.1 exhibited lower bacterial populations during storage. The sensory characteristics (color, juiciness, flavor, tenderness, and overall acceptability) did not differ significantly in all deep fried chicken nugget samples, except color, whereas storage time had a significant effect (P<0.05). The results suggest the possibility of utilizing raw and deep fried chicken nuggets with a mixture of ganghwayakssuk and ascorbic acid for the increase of shelf-life and quality.

Development of Monacolin K-Enriched Ganghwayakssuk (Artemisia princeps Pamp.) by Fermentation with Monascus pilosus

Monacolin K-enriched ganghwayakssuk (Artemisia princeps Pamp.) was developed by fermentation with Monascus sp. Among the 15 Monascus spp. isolated previously from Monascus fermentation products, Monascus pilosus KMU108 produced 2,219 mg/kg of monacolin K during ganghwayakssuk fermentation with no detectable citrinin. The optimum concentrations of ganghwayakssuk and glucose determined from the response surface methodology (RSM) design were 2.2% and 3.8%, respectively. By applying these conditions, the monacolin K productivity was increased to 3,007 mg/kg after 15 days of fermentation. On the other hand, other characteristics such as the total content of flavonoids and phenolic compounds, and the antioxidant activity were relatively unchanged. Therefore, Monascusfermented ganghwayakssuk is an excellent biomaterial for the development of functional foods because of its high level of monacolin K, known to lower cholesterol levels.

Effect of Ganghwayakssuk (Artemisia princeps Pamp.) on oxidative stability of deep fried chicken nuggets

This study was conducted to examine the antioxidant effects of various levels of added ganghwayakssuk (Artemisia princeps Pamp.) extract on deep fried chicken nuggets. The frying loss, pH, and yellowness values of all treatments were higher than those of the control (p<0.05). Additionally, the lightness and redness values of all treatments were lower than those of the control and as the amount of ganghwayakssuk ethanolic extracts (GEE) increased. At the end of the storage period (day 10), the peroxide values (POV), conjugated dienes (CD), and thiobarbituric acid reactive substances (TBARS) values were lower than those of the control. The sensory evaluation of all samples was not different significantly at the early days of storage (p<0.05). With increases in the storage period, deep fried chicken nuggets containing various levels of GEE had higher overall acceptability than those of the control. The results demonstrate that ganghwayakssuk has strong lipid antioxidation activity added to deep fried chicken nuggets.

Artemisia princepsPamp. Essential Oil and Its Constituents Eucalyptol andα-terpineol Ameliorate Bacterial Vaginosis and Vulvovaginal Candidiasis in Mice by Inhibiting Bacterial Growth and NF-κB Activation

To investigate the inhibitory effects of Artemisia princeps Pamp. (family Asteraceae) essential oil (APEO) and its main constituents against bacterial vaginosis and vulvovaginal candidiasis, their antimicrobial activities against Gardnerella vaginalis and Candida albicans in vitro and their anti-inflammatory effects against G. vaginalis-induced vaginosis and vulvovaginal candidiasis were examined in mice. APEO and its constituents eucalyptol and α-terpineol were found to inhibit microbe growths. α-Terpineol most potently inhibited the growths of G. vaginalis and C. albicans with MIC values of 0.06 and 0.125 % (v/v), respectively. The antimicrobial activity of α-terpineol was found to be comparable to that of clotrimazole. Intravaginal treatment with APEO, eucalyptol, or α-terpineol significantly decreased viable G. vaginalis and C. albicans numbers in the vaginal cavity and myeloperoxidase activity in mouse vaginal tissues compared with controls. These agents also inhibited the expressions of proinflammatory cytokines (IL-1 β, IL-6, TNF- α), COX-2, iNOS, and the activation of NF- κB and increased expression of the anti-inflammatory cytokine IL-10. In addition, they inhibited the expressions of proinflammatory cytokines and the activation of NF- κB in lipopolysaccharide-stimulated peritoneal macrophages, and α-terpineol most potently inhibited the expressions of proinflammatory cytokines and NF- κB activation. Based on these findings, APEO and its constituents, particularly α-terpineol, ameliorate bacterial vaginosis and vulvovaginal candidiasis by inhibiting the growths of vaginal pathogens and the activation of NF- κB.

At the end of the storage period (10 d), the peroxide values (POV), conjugated dienes (CD),and thiobarbituric acid reactive substances (TBARS) values were lower than those of the control. The results show thatGanghwayakssuk prevents lipid oxidation in raw chicken nugget batter.Key words: antioxidants, Ganghwayakssuk (Artemisia princeps Pamp.), lipid oxidation

Anti-Inflammatory Effect of Fermented Artemisia princeps Pamp in Mice

Abstract － Essential oil-excluded Artemisia princeps Pamp var Ssajuarissuk (AP) was fermented with Lactobacillus brevis K-1, which was isolated from cabbage Kimchi, and the anti-inflammatory effects of AP and fermented AP (FAP) on lipopolysaccharide (LPS)-induced inflammatory response in peritoneal macro-phages were investigated. AP and FAP inhibited LPS-induced TNF-α, IL-1β, COX-2, iNOS and COX-2 expression, as well as NF-κB activation. AP and FAP also reduced ear thickness, inflammatory cytokine (TNF-α, IL-1β and IL-6) expression and NF-κB activation with 12-O-tetradecanoylphorbol-13-acetate (TPA) induced dermatitis in mice. Furthermore, AP and FAP also reduced exudate volume, cell number, protein amount, inflammatory cytokines (TNF-α, IL-1β and IL-6) expression and NF-κB activation in carrageenan- induced air pouch inflammation in mice. The inhibitory effects of FAP were more potent than those of non-fermented AP. Based on these findings, we propose that FAP can improve inflammatory diseases, such as dermatitis, by inhibiting the NF-κB pathway.Keywords:

Radical scavenging activity and anti-obesity effects in 3T3-L1 preadipocyte differentiation of Ssuk (Artemisia princeps Pamp.) extract

Radical scavenging activity of ethanol extracts from ssuk (Artemisia princeps Pampan.) was determined by 2,2-diphenyl-1-pycryl-hydrazil (DPPH) and 2,2′-azinobis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) methods. Also, anti-obesity effects of ssuk extract were tested in vitro using 3T3-L1 preadipocyte cells. Total phenolic contents of ssuk extract were 42 μM tannic acid equivalent/mg and EC50 of ssuk extract for scavenging DPPH and ABTS radicals were 2.02 and 1.03 mg/mL, respectively. Triacylglycerol content in 3T3-L1 preadipocyte cells treated with 25, 50, and 100 αg/mL ssuk extract decreased significantly by 63.3, 67.1, and 71.0%, respectively (p<0.05) compared to those in untreated cells. Also, ssuk extract induced the down-regulation of adipogenesis-related genes such as PPARγ, aP2, ACC, and GPDH. The ssuk extract possessed phenolic compounds with radical scavenging ability and had in vitro anti-obesity effects on 3T3-L1 preadipocyte cells. These results suggest that the extracts of ssuk may be used as obesity controlling food ingredients.
