Artemisia annua L. is a widely distributed medicinal plant and well-known for treating malaria due to the artemisinin content. We previously found enhanced antioxidant and antibacterial activities of Lactobacillus plantarum-fermented A. annua dried leaves in vitro. The present study compared the effects of the dietary supplementation of L. plantarum, fermented (FA) or non-fermented (NFA) A. annua on laying performance, egg quality, serum cholesterol, and egg yolk oxidative stability during storage in 40-weeks-old Hy-Line Brown layers. In total, 180 layers were randomly allocated into four treatments for 6 weeks: basal diet (CON), basal diet + 0.5% L. plantarum only (LO), basal diet + 0.5% NFA, and basal diet + 0.5% FA. Each treatment comprised five replicates with nine birds each. Egg weight of NFA and FA groups were significantly higher as compared with the CON and LO groups (p<0.01). The FA group displayed higher Haugh unit (HU) compared with the NFA group (p<0.05). Eggshell color of the FA group was significantly increased compared with the other groups (p<0.01). There was no significant difference in triglyceride, total cholesterol, HDLcholesterol, and VLDL+LDL cholesterol among the different groups. During egg storage, the HU of FA groups was significantly increased as compared with the CON group after 3 weeks storage (p<0.05). The malondialdehyde (MDA) content in the stored eggs was significantly lowered by feeding of FA as compared with the CON and LO groups (p<0.05). Altogether, the fermented A. annua displayed positive effects in promoting egg quality of layers.

“…Artemisia ordosica is a semi-shrubby plant of the genus Artemisia, mainly distributed in north and northwest sandy grassland of China, which not only contains rich nutrients -its flowering crude protein content reached 17.94%, crude fat content is 7.74%, but is also rich in polysaccharides, flavonoids, organic acids and other bio-active compositions, and the whole plant can be used as medicine. In recent years, studies about the effect of Artemisia plants on animals are more concentrated in wormwood and Artemisia annua L. (Li et al 2015;Wan et al 2016), but the impact of Artemisia ordosica is rarely reported.…”

DietaryArtemisia ordosicaextract alleviating immune stress in broilers exposed to lipopolysaccharide

et al. 2017

This study was conducted to investigate the effect of Artemisia ordosica extract (AOE) on broilers challenged with lipopolysaccharide (LPS). 96 one-day-old Arbour Acres broilers were assigned in 2 Â 2 factorial design, including two dietary treatments (0 or 1000 mg/kg AOE) and two immunological challenge (saline or LPS). on d 14, 16, 18 and 20, broilers were injected intra-abdominally with LPS solution (the LPS was dissolved in sterile saline at a concentration of 100 lg/mL) at 500 lg/kg of base weight, or an equivalent amount of sterile saline. Blood samples were collected on d 21 and 28. During LPS-challenged periods (days 15-21), AOE alleviated the compromised average daily gain and average daily feed intake (p < .05) in broilers challenged with LPS. On day 21, the LPS challenge increased (p < .05) serum adrenocorticotropic hormone, corticosterone, interleukin-1, interleukin-2, interleukin-6, immunoglobulin G and immunoglobulin A, decreased (p < .05) the content of serum growth hormone and insulin-like growth factor-1. However, diet supplemented with AOE reduced the elevation of serum corticosterone (p ¼ .054), interleukin-2 (p < .05), immunoglobulin A (p < .05) and immunoglobulin G (p ¼ .079) caused by LPS on day 21. After a week's recovery, on d 28, AOE reduced the serum interleukin-6 content (p < .05). It may be that AOE exert its beneficial effect on broilers challenged with LPS by lessening the inflammatory cytokines and stress hormone, weakening the over activated immune system and finally, improving the growth performance.ARTICLE HISTORY

“…The treatment with the highest reducing power was the solution of 10 mg/mL of water extract with an absorbance value of 0.55. Furthermore, many studies performed with different plant species such as Eruca sativa [Sarwar Alam et al 2007], Rumex vesicarius [Beddou et al 2015], Artemisia annua [Wan et al 2016] and Momordica charantia [Svobodova et al 2017] in previous years revealed that reducing power activity increased in concentration-dependent manner.…”

EVALUATION OF ANTIOXIDANT ACTIVITY OF in vitro PROPAGATED MEDICINAL Ceratophyllum demersum L. EXTRACTS

Ceratophyllum demersum L. is a medical plant of the family Ceratophyllaceae that has been traditionally used for the treatment of diseases such as ulcer, diarrhoea, wounds and fever since ancient times. This study presents antioxidant activities of water and methanol extracts of in vitro propagated C. demersum. Shoot tip explants of C. demersum for in vitro plant regeneration were cultured on liquid Murashige and Skoog (MS) medium containing 0.25-1.25 mg/L 6-Benzylaminopurine (BAP) and 0.10 mg/L Thidiazuron (TDZ) combinations for eight weeks. Maximum number of plantlets per explant (110.67) was obtained on MS medium supplemented with 0.75 mg/L BAP + 0.10 mg/L TDZ. In order to determine antioxidant activities of C. demersum, antioxidant contents (β-carotene, flavonoid, lycopene and total phenols), metal chelating and reducing power capacities of methanol and water extracts obtained from C. demersum were investigated. It was detected that water extract was more effective in all activities. Total phenols (76.55 μg/mg) in water extract were measured as the highest antioxidant component. Based on the water extracts data, as IC 50 value for chelating on ferrous ions was 9.24 mg/mL, EC 50 value for reducing power activity was 8.23 mg/mL. It was also determined that the metal chelating and reducing power activities of the both extracts are increased depending on the concentration. Therefore, all these data suggest that both tested extracts of in vitro propagated C. demersum would exert beneficial effects by virtue of their antioxidant properties and may be utilized as a promising source of therapeutics.
