Toxicity of seed extracts of four indigenous plants, Luffa acutangula (Roxb.), Areca catechue (Linn.), Brassica nigra (Linn. Koch.) and Brassica hirta (Monech) was tested on three predatory fishes- Heteropneustes fossilis (Bloch), Anabas testudineus (Bloch) and Channa punctatus (Bloch) under normal laboratory conditions. Due to the toxic effect of different seed extracts and concentrations, mortality rate varied. It also varied from species to species. On the basis of LC50 values of absolute ethyl alcohol extracts, L. acutangula seed extracts were more toxic for H. fossilis and A. testudineus. A. catechue seed extracts were of medium toxicity for all the experimental fishes. B. nigra seed extracts were less toxic whereas B. hirta seed extracts showed differential toxicity being more toxic for C. punctatus, medium for A. testudineus and less toxic for H. fossilis. The susceptibility pattern also varied in the three fish species. In case of L. acutangula, A. catechue and B. nigra seed extracts, the susceptibility was in the same order: H. fossilis > A. testudineus > C. punctatus but the effect of B. hirta seed extracts was reverse. To determine the ichthyotoxicity of the four seed extracts on the three predatory fishes, the present study was undertaken. DOI: http://dx.doi.org/10.3329/cujbs.v6i1-2.17079 The Chittagong Univ. J.

Toxic responses of distilled water, 50% ethyl and absolute ethyl alcohol extracts of six indigenous plants, Datura innoxia (Mill), Clerodendrum viscosum (Vent), Amoora rohituka (Roxb) Wt. et. Arnott, Acacia auriculaeformis A. Cunn. ex. Benth., Pongamia pinnata (L) Pierre and Acacia catechu Willd were studied on a predatory fish Heteropneustes fossilis (Bloch) in laboratory conditions. Amongst the extracts the toxicity range varied, absolute ethyl alcohol extract of A. rohituka seeds being the most toxic (LC50 = 8.67 ppm) whilst distilled water extract of D. innoxia seeds was the least toxic (LC50 = 1950.03 ppm). On the basis of LC50 and relative potency values the relative toxicity of the six plants was in the order- A. rohituka > C. viscosum > P. pinnata > A. auriculaeformis > A. catechu > D. innoxia seed extracts. These six indigenous plant seed extracts assayed might be helpful as controlling agent of undesirable fishes in fish culture ponds.

Haemolytic effects of different extracts of five indigenous plant seeds viz. Datura innoxia (Mill) (Shada Dhutra), Clerodendrum viscosum (Vent.) (Vat), Amoora rohituka (Roxb.) Wt. ct. Arnott (Pitraj), Acacia auriculiformis A. Cunn. Ex. Benth. (Akashmoni) and Pongamia pinnata (L.) Pierre (Karinja) were studied upon a predatory fish, Singhi, Heteropneustes fossilis (Bloch) under laboratory conditions. Toxicants inducing effects on the blood parameters included decreased RBC and WBC counts, low haemoglobin percentage and decreased PCV (packed cell volume), MCV (mean corpuscular volume) and MCH (mean corpuscular haemoglobin). Haemolysis action included shrunken or swollen RBCs, granulated nuclei of RBCs and pyknotic nuclei of WBCs, clumping of RBCs and syncitium of RBC matrix. Damage of blood cells with absolute ethyl alcohol extract was most pronounced with all of the seed extracts. The order of toxicity of the five seed extracts on the blood parameters of Singhi was: D. innoxia < A. auriculaerformis < P. pinnata < C. viscosum < A. rohituka seed extracts. On the basis of haemolysis the toxicity was: A. rohituka > C. viscosum > P. pinnata > D. innoxia > A. auriculiformis seed extracts.

For the removal of undesired fish species from aquaculture ponds, an alternative to synthetic toxins is the use of botanical toxicants which are biodegradable and environmentally safer. Toxicological effects of distilled water, 50% ethyl alcohol, methanol and acetone extracts of three indigenous plant seeds, Jatropha carcus (Linn.), Hydnocarpus wightianus (Blume) and Aleurites moluccana (Linn. Willd) were studied on the predatory fish, Heteropneustes fossilis (Bloch) under normal laboratory conditions. Depending upon the type of plants, extracts and concentrations, percentage mortality varied. Behavioral activities increased with increasing concentrations. During exposure, fish exhibited discolouration, gulping for air, erratic swimming, loss of reflex, slow movement and ultimately became motionless before death . The extent of toxicity of extracts for J. carcus, H. wightianus and A. moluccana on H. fossilis could be ranked in the order: Acetone > methanol > 50% ethyl alcohol > distilled water. On the basis of LC50 values the most toxic was acetone extract of J. carcus seeds and least toxic was distilled water extract of A. moluccana seeds. It is suggested that these plant seed extracts would be helpful in aquaculture to remove unwanted fish species from culture ponds. Bangladesh J. Zool. 48(2): 379-391, 2020

Seed Extracts

The antimicrobial, antioxidant, and anticholinesterase activities of ethanolic seed extracts of twenty-one plant species from Brazilian semiarid region were investigated. The extracts were tested for antimicrobial activity against six bacteria strains and three yeasts. Six extracts presented activity against the Gram (−) organismSalmonella choleraesuisand the Gram (+) organismsStaphylococcus aureusandBacillus subtilis. The MIC values ranged from 4.96 to 37.32 mg/mL. TheTriplaris gardnerianaextract presented activity against the three species, with MIC values 18.8, 13.76, and 11.15 mg/mL, respectively. Five extracts presented antioxidant activity, with EC50values ranging from 69.73 μg/mL (T. gardneriana) to 487.51 μg/mL (Licania rigida). For the anticholinesterase activity, eleven extracts were capable of inhibiting the enzyme activity. From those,T. gardneriana,Parkia platycephalaandConnarus detersuspresented the best activities, with inhibition values of 76.7, 71.5, and 91.9%, respectively. The extracts that presented antimicrobial activity were tested for hemolytic assay against human A, B, and O blood types and rabbit blood. From those, only theMyracrodruon urundeuvaextract presented activity (about 20% of hemolysis at the lowest tested concentration, 1.9 µg/mL). Infrared spectroscopy of six representative extracts attested the presence of tannins, polyphenols, and flavonoids, which was confirmed by a qualitative phytochemical assay.

Epilachna Vigintioctopunctata

Epilachna vigintioctopunctata is an important pest that causes considerable economic losses to many crops including egg-plants. The crude aqueous extracts of leaves from three indigenous plants namely Ricinus communis, Calotropis procera and Datura metel were used against this beetle aiming at its control under laboratory conditions. Larvicidal bioassays of the extracts showed the following order of toxicity: R. communis (LC50=18.40%) > C. procera (LC50=23.70%) > D. metel (LC50=29.61%). Subsequent data on some vital life-history traits were promising because the extracts significantly reduced both oviposition and egg-hatch, prolonged larval duration (P<0.001), and inhibited pupae formation and adult emergence (P<0.05). However, female ratio was not significantly affected by the treatments. Relevance of these findings on the control of this phytophagous species has been discussed.

Seed Extracts

The CH2Cl2-MeOH (30:70 v/v) extracts of the seeds of Mangifera indica (Mango), Persea americana (Avocado) and Dacryodes edulis (African plum) were evaluated for potential mosquito larvicidal activity against 3rd and 4th instar larvae of Aedes aegypti, Culex quinquefasciatus and Anopheles gambiae. Extracts were diluted with 1 mL of methanol and concentrations ranging from 1000 to 125 mg/L in 4 replicates each, were prepared in the volume of 100 mL in the plastic cups (250 mL). A volume of 1 mL of methanol added to 99 mL of tap water was prepared as negative control and Bi-one (1000 mg/L) constituted a positive control. In each test solution, 25 larvae of each mosquito species were separately transferred and larval mortality was recorded after 24 h post-treatment. As results, the three plant seed extracts applied at 1000 mg/L caused for at least 79% mortality of each mosquito species larvae assessed. The seed extract of P. americana (LC50 of 98.31, 129.24 and 136.26 mg/L, respectively against An. gambiae, Ae. aegypti and Cx. quiquefasciatus larvae) was the most potent followed by D. edulis (LC50 of 176.87 mg/L for An. gambiae, 198.68 mg/L for Ae. aegypti and 201.70 mg/L for Cx. quinquefasciatus) and M. indica (LC50 of 258.98 mg/L for An. gambiae, 297.35 mg/L for Ae. aegypti and 435.45 mg/L for Cx. quinquefasciatus).  Globally, all the seed extracts were more toxic against An. gambiae larvae compared to other mosquito species and need further exploration for the development of a new botanical larvicide to reduce mosquito densities.
