Abstarct: A molecular phylogenetic analysis of some Holothuroidea was undertaken in order to clarify the systematics and taxonomy of this class in the red sea. DNA sequence for portions of 16S mitochondrial genes was obtained from 4 species of sea cucumbers. The resulting molecular phylogeny using maximum likelihood methods of the Holothuroidea conflicting existing taxonomy, which is based larg...
Teripang merupakan komoditas perikanan yang saat ini dibudidayakan dan dieksploitasi di perairan Lampung. Namun terdapat kesulitan dalam mengidentifikasi teripang karena kemiripan morfologis antara spesies ada. Identifikasi baik berguna agar proses pembudidayaan konservasi dapat tepat sasaran. Penggunaan DNA barcoding digunakan untuk jenis-jenis ada, jarak genetik, keragaman genetik intra/inter...
خیارهای دریایی تولید کننده انواع مختلفی از ترکیبات طبیعی زیست فعال به ویژه متابولیتهای ثانویه از جمله ساپونین می باشند. هدف از مطالعه حاضر بررسی فعالیت ضد باکتریایی ساپونین استخراج شده از خیار دریایی گونه (Stichopus hermanni) جمع آوری شده از خلیج فارس در برابر برخی باکتریهای گرم مثبت و منفی بود. ابتدا عصارهگیری با اتانول70% انجام شد و به منظور جداسازی ساپونین، عصاره اتانولی تغلیظ شده بر روی س...
compounds obtained from marine organisms have been isolated due to their anti-bacterial and antifungal activities. in this study, the antifungal activity of aqueous-methanol, methanol, chloroform and n-hexane extracts of body wall, guts and white strings of sea cucumber (holothuria leucospilota) collected from chabahar bay in 100 to 2000 μg/ml concentrations is discussed. the antifungal test on...
Description of a new species from Australia, belonging to the subgenus Selenkothuria (Holothuria, Aspidochirotida). A dichotomous key of the thirteen valid species included in the subgenus is also given. The species H. perrieri Thandar, 1977 and H. spinea Cherbonnier, 1988 are considered as non valid.
More than 100 triterpene glycosides (saponins) have been characterized in holothuroids in the past several decades. In particular, Holothuria forskali contains 26 saponins in its Cuvierian tubules and 12 in its body wall. This high diversity could be linked to a chemical defense mechanism, the most commonly accepted biological role for these secondary metabolites. We performed an integrated stu...
Objective(s):Marine organisms are known as a potential source of natural products, which contain bioactive substances with therapeutic properties. Sea cucumbers are prominent among marine organisms because of their dietary and therapeutic applications. In addition, they have capacity of synthesizing saponins molecules and other metabolites with therapeutic properties such as antitumor, antimicr...
