Background : Obvious applications of aloe (Aloe vera) and their rapid intake make it crucial to evaluate their biological impacts to aquatic organisms. Methods and Results : In this study, we investigated the possible effects of aloe extract on zebrafish embryos (Danio rerio) by assessing teratogenic properties including survival rate, hatching success, heart rate and morphological changes for 96hpf (hours post fertilization). We noticed that exposure to aloe extracts (0.1, 10, 50, 100 and 150 μl/ml in embryo medium) to zebrafish embryos showed no alterations in survival and morphological changes when compared to control embryos. In contrast, embryos exposed to 150 μl/ml of aloe extract shows delayed hatching rate at 72hpf when compared to lower concentrations. Similarly, aloe extract at 150 μl/ml exposed embryos elicited significantly reduced heart rate (132 ± 1 beats/min) at 48hpf when compare to control embryos. Conclusion : Based on the above findings, we speculate the teratogenic effect of aloe extract on zebrafish embryos.

Background : Oxidative stress condition refers as disturbed homeostasis between the generation of reactive oxygen species (ROS) and the antioxidant system that results in severe pathological conditions. To balance such an oxidative stress condition external antioxidant sources are required. Methods and Results : In view of the above, present study was carried out to investigate the cytoprotective role of the strawberry (Fragaria × ananassa var. Seolhyang) root extract (SRE) against oxidative stress condition stimulated by H2O2 in murine macrophages Raw 264.7 cells and further evaluation of intracellular ROS level, lipid peroxidation and myeloperoxidase (MPO) activity as oxidative stress markers. Cytoprotective effect of SRE was evaluated by quantifying survival of macrophages challenged by H2O2 in presence and absence of SRE. Finding suggest a 60.1 ± 7.5% cell survival in H2O2 treated cells as compare to 100% survival in control cells. However, a significant increase in cell survival with 62.7 ± 2.9, 74.2 ± 5.2 and 81.3 ± 3.3% were observed in the cells treated with 2.5, 5, 10 μg/ml of SRE respectively. A reduced ROS level together with inhibition of the lipid peroxidation and MPO activity was observed in the cells treated with SRE as compare to only H2O2 treated cells. Conclusion : Our results signify the potency of SRE to protect the cells from oxidative stress implied by H2O2 and can be used as a source of antioxidant for health benefits.

Background : Agastache rugosa (A.rugosa), belongs to the Labiatae family, is a perennial plant distributed in Korea, Japan, Taiwan and China. It is commonly called korean mint and commercially consumed as a medicinal plant in many countries since the crop contains monoterpenes and phenylpropanoids including rosmarinic acid, tilianin and acacetin. Achievement of hairy root cultures (HRCs) through infection of A rhizogenes is a valuable alternative approach, resulting from genetic and biochemical stability, rapid growth rates and synthesis of natural products. Methods and Results : The hairy root, obtained from the explant of A.rugosa, was cultured in the basal half-strength MS (Murashige & Skoog) medium. The dry weights (DW) of hairy roots was measured after 4-days freeze dryer. The highest levels of DW were obtained at hairy roots cultured in the basal medium supplemented with glucose, galactose and sucrose. The lowest weight was recorded after HRCs in the control, meant that the medium did not contain any carbon sources. Sucrose, glucose and galactose are the most suitable for the growth of korean mint hairy roots. the rosmarinic acid contents in the hairy roots varied responding to various carbohydrates. The basal media added with sucrose resulted in the highest value of rosmarinic acid, followed by the basal media with galactose and glucose. The control showed the lowest amount of rosmarinic acid. Conclusion : In this study, carbon source are of importance for growth and accumulation of rosmarinic acid accumulation in korean mint hairy roots. Especially, the accumulation of rosmrinic acid and hairy root growth was the most appropriate carbohydrate. The current study suggests HRCs of korean mint could provide an valuable alternative approaches for the enhanced production of rosmarinic acid.

Background : Nasturtium officinale, belongs to the Brassicaceae, is a perennial plant growing in and around natural watersystem. It is commonly called watercress and commercially consumed as a salad crop in many countries. Hairy root cultures (HRCs), transformed by Agrobacterium rhizogenes (A. rhizogenes), have been noted for an experimental model system in plant metabolic engineering for the synthesis of natural products since hairy roots have fascinating properties including biochemical and genetic stability, high biosynthetic capacity for secondary metabolites and rapid growth rates. Methods and Results : The dry weights (DW) of watercress hairy roots was measured after 4-days freeze dryer. The highest weight was recorded after HRCs in SH and half-strength SH medium, followed by the levels of DW in MS and half-strength medium. However, the level of DW after HRCs in half-strength medium was lowest. SH medium is the most suitable for the growth of watercress hairy roots. Glucosinolate contents in the hairy roots varied responding to the basal media. 1/2 SH basal media resulted in the lowest value of total glucosinolate. MS basal media, however, resulted in the highest value of total glucosinolate, as well as the highest accumulation of each glucosinolate. The hairy roots cultured in 1/2 MS basal media showed the second highest value of total glucosinolate, followed by B5, SH and 1/2 B5. The accumulation of 4-Methoxyglucobrassicin and gluconasturtiin was also secondly higher in the hairy roots in 1/2 MS. In contrast, the level of 4-Hydroxyglucobrassicin and glucobrassicin were the second highest after culturing in SH and B5, respectively. Conclusion : In this study, media played a main role in growth and glucosinolate accumulation in watercress hairy roots. SH and half-strength SH media enabled the rate growth of hairy roots to be highest. In contrast, the highest accumulation of glucosinolate was recorded after HRCs in MS media. The current study suggests HRCs of watercress could be one of an effective alternative approaches for the enhanced production of glucosinolates
