Research Journal of Biotechnology, 2026
The study of preliminary investigation on phytochemical analysis of Ananas comosus and Ziziphus nummularia plays a vital role in secondary metabolites. In the present investigation, phytochemical screening identification shows the highest percentage of triterpenoids (98%), followed by phenolic compounds (65%) and alkaloids (86%), which is compared to the polar solvent concentration. The PET ≤ chloroform ≤ methanol ≤ ethanol ≤ H₂O of Z. nummularia were compared to the activity of the A. comosus (L) extract. These investigations assist in identifying particular molecules such as polysaccharides, alkaloids, carbohydrates, tannins, flavonoids and triterpenoids, that contribute to a range of biological activities. FTIR analysis was employed to identify the functional groups in the ethanolic extract of Ziziphus nummularia. The presence of broad O–H stretching at 3398.88 cm⁻¹, C=O stretching at 2975.40 cm⁻¹ and C–O stretching around 1050.10 cm⁻¹ confirmed the existence of alcohols, flavonoids and phenolic compounds. Further, the samples are taken to gas chromatography MS analysis, which is totally around (48) bioactive compounds, which vary in amount by main component. They are identified as the highest peak (34.65%) in 9- Phenanthrenemethyl 2,6-benzoate, (34.46%) in Terephthalic acid, (32.92%) in Cyclotrisiloxane, (33.50%) in 2,3,4,6-Tetrahydroisoquinolin-6-one and (31.5%) in Caprolactone oxime. These compounds are identified as various forms of potential toxicity in Ziziphus nummularia.(l) extract by anti-inflammatory activities and new drug development. It led to exploring for potential use in new drug development, particularly in areas like anti-inflammatory and antioxidant therapies - Report on high density population of a Cladoceran, Moina macrocopa and their gut microbes in anoxic sewage water: a potential bio-indicator of aquatic pollution

Purpose: The effect of low level cobalt-60 (60Co) gamma radiation on the freshwater prawn Macrobrachium rosenbergii was evaluated by observing their hemocyte counts and biochemical parameters.Materials and methods: Prawns were exposed to 3, 30, 300 and 3000 milligray (mGy) dose levels and their tissues of gills, hepatopancreas and muscle were analyzed.Results: The results showed that the number of hemocytes in the hemolymph and concentrations of protein and carbohydrate were significantly reduced in irradiated groups than compared to the control prawn. Increased aspartate transaminase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), Acetyl choline esterase (AChE) in the irradiated groups reflects tissue damage.Conclusions: Hence, this study concludes that even low level of ionizing radiation (60Co gamma) can cause acute damages in gills, hepatopancreas and muscles in irradiated groups.Highlights60Co exposures effect the THC and biochemical of prawn M. rosenbergii.Different dose levels such as 3, 30, 300 and 3000 mGy.Biochemical parameters serve as reliable indicators of physical status of organism.Self-regulating mechanisms might be the reason for preventing from the lethality.Suggested that nuclear industries should manage below 3 mGy. - Impact of chlorpyrifos on behavior and histopathological indices in different tissues of freshwater fish Channa punctatus (Bloch)

The present study was designed to evaluate the effect of acute level of 60Co gamma radiation on fecundity of freshwater prawn Macrobrachium rosenbergii. Prawns were exposed to four different dose levels (3, 30, 300 and 3000 mGy) and their reproductive disturbances i.e Gonadosomatic Index (GSI), Egg Clutch somatic Index (ESI), Egg Counts and Egg hatching rates were calculated. The experimental group showed significant reduction in GSI (0.47 ± 0.01) & ESI (1.22 ± 0.08) after exposure to 60Co gamma radiation. Egg Count (3713 ± 21) and Egg hatching rates (3798 ± 11) were significantly reduced in all irradiated groups. The number of dead larva increased with the increasing level of doses. With the increase in dosage level, the gonad and egg clutch weight were decreased which likely lead to reduced number of eggs. Our results proved that even low level of ionizing radiation (60Co) affects the fecundities of freshwater crustacean M. rosenbergii. - Morphological and histological studies on freshwater prawn Macrobrachium rosenbergii (de man) irradiated with 60Co gamma radiation
