Microplastics are one of the major pollution problems nowadays, have been found in both marine environments and various fish species worldwide. In this study, presence microplastics digestive systems gills 6 from Scombridae family on coast Karachi Pakistan was investigated. A total 336 were examined for microplastic systems. detected 11.11%-19.51% 58.62%-85.71% individuals, respectively. The nu...

The conventional taxonomy on sea cucumbers is challenging due to their morphological complexity. Molecular investigation of the class Holothuroidea was initiated for further clarity regarding systematics and this class. A molecular phylogeny constructed by using maximum likelihood methods, unveiled variation in existing taxonomic classification, which largely based morphology calcareous parts. ...

The ethyl acetate soluble part of a methanolic extract of the marine green alga Codium iyengarii, collected from the Karachi coast of the Arabian Sea, afforded four new derivatives of glycerol named : codioside A,B,C,D (1-4), a new derivative of frans-phytol named codioester (5) and rrans-phytol (6). The structures of 1-5 were elucidated with the aid of acid hydrolysis, methylation, GC-MS, and ...

Marine algal community signifies a huge source of compound endowed with ingenious structure and potential biological activities. Cytotoxicity of plant or fungal material is considered as the presence of antitumor compounds. In this study, ethanol extracts of seaweeds Dictyota dichotoma var. velutricata, D. hauckiana, D. indica, Iyengaria stellata, Jolyna laminarioides, Melanothamnus afaqhusaini...
