“…Therefore, LC 50 values obtained in this study indicate moderate toxicity for the plant extracts. In addition, it was suggested that, if crude extracts possessed LC 50 values less than 250 µg/mL they could be considered significantly active and have the potential for further investigation (Nair, Anju & Hatha, 2017). Therefore, the preliminary cytotoxic activity exhibited by the extracts was promising and this clearly indicated the presence of potent bioactive compounds.…”

An attempt has been made to evaluate antimicrobial, antioxidant and cytotoxicity properties of extracts from onion (Allium cepa L.), garlic (Allium sativum), leaves of guava (Psidium guajava), papaya (Carica papaya), tea (Camellia sinensis), baen (Avicennia alba) and keora (Sonneratia apetala), respectively to apply as natural preservatives for tomatoes. The air-dried plant materials of the respective plant species were subjected to ethanol-methanol extraction, concentrated and stored at 4 °C before use. The extracts were dissolved in 95% ethanol for analysis of antioxidant and antimicrobial properties. Of the extracts tested, tea extracts showed the highest zone of inhibition against several pathogenic bacteria (E. coli 35.0±3.2 mm; P. aeruginosa 29.3±2.6 mm; S. typhi 28.4±2.1 mm and S. pyogenes 27.7±3.7 mm) using the disc diffusion method. In regard to DPPH free radical scavenging assay, keora and guava extracts showed the highest percentage of radical scavenging activity with the values of 89.64± 0.18 and 89.39± 0.88, respectively, which were in agreement with higher total antioxidant capacity (TAC) of these extracts obtained by the phosphomolybdenum method. Brine shrimp lethality bioassay for cytotoxicity assessment showed LC50 of 132.54 ± 18.99 µg/mL for the leaf extract of keora which was found to be most toxic among all studied extracts. The initial results indicated that the extracts could be used for food preservative applications based on the antimicrobial, antioxidant and cytotoxicity properties of the tested extracts. However, efficacy, stability and safety issues need to be addressed with both in vitro and in vivo studies.

“…Intensive aquaculture often leads to infectious disease causing significant loss to the farmers (Harikrishnan et al, 2011). This has created research interest in the use of phytogenic feed additives (PFAs) as digestive stimulants, growth promoters, anti-stress factors, immunestimulants and bactericidal agent in aquafeed, which have no residual and side effects in fish (Lee et al, 2015;Nair et al, 2017). Published reports have confirmed that supplementation of PFAs in aquafeed has improved the health status in fish probably due to the action of bioactive compounds (polyphenols, flavonoids etc.)…”

Aim: The present experiment was undertaken to compare digestive, metabolic, antioxidant enzyme activities and immuno-biochemical responses in Labeo rohita fingerlings to some commonly used phytogenic feed additives. Methodology: Eleven experimental diets were prepared by supplementing fennel, coriander, cumin, fenugreek seed, turmeric, black pepper, peeled ginger, bay leaf, peeled onion bulb or peeled garlic clove meal at 1% inclusion level along with a control diet. Four hundred and ninety-five fingerlings (average weight 6.45±0.01 g) were distributed randomly in eleven experimental groups in triplicates with a stocking density of 15 fish per tank (400 l of water). Results: Turmeric, garlic or ginger meals appeared to be more effective than onion, fenugreek, cumin, coriander, fennel, black pepper and bay leaf meals for enhancing digestive, metabolic, antioxidant enzyme activities and innate immune functions. The physio-metabolic effects of phytogenic feed additives tested in Labeo rohita fingerlings were in the order of turmeric > garlic > ginger > onion > fenugreek > cumin > coriander > fennel > black pepper > bay leaf meal. Interpretation: The enhanced digestive and metabolic enzyme activities, antioxidant function, glucose homeostasis and improved innate immune function through modulation of the haemato-biochemical profile of Labeo rohita due to feeding of specific functional compounds present in turmeric, ginger and garlic meals compare to other phytogenic additives.
