“…The preliminary phytochemical constituents showed the presence of saponins, steroids, terpenoid, phenols, protein, and sugars [39]. Hexadecanoic acid, tetradecanoic acid, 2hydroxyhexadecanoic acid, palmitic acid, elaidic acid, stearic acid, cis-11,14,17-eicosatrienoic acid, and erucic acid were isolated from D. dichotoma, collected at Pulau Nunuyan Laut, Sandakan, Sabah, with the contents of the co-occurring poly-and mono-unsaturated fatty acids being higher than the saturated fatty ones [40].…”

Although a broad variety of classes of bioactive compounds have already been isolated from seaweeds of the genus Dictyota, most different species are still chemically and biologically unexplored. Dictyota species are well-known brown seaweeds belonging to the Dictyotaceae (Phaeophyta). The phytochemical composition within the genus Dictyota has recently received considerable interest, and a vast array of components, including diterpenes, sesquiterepenes, sterols, amino acids, as well as saturated and polyunsaturated fatty acids, have been characterized. The contribution of these valued metabolites to the biological potential, which includes anti-proliferative, anti-microbial, antiviral, antioxidant, anti-inflammatory, and anti-hyperpigmentation activities, of the genus Dictyota has also been explored. Therefore, this is the most comprehensive review, focusing on the published literature relevant to the chemically and pharmacologically diverse biopharmaceuticals isolated from different species of the genus Dictyota during the period from 1976 to now.

“…Apart from having unique bioactive secondary metabolites with medicinal properties [14], seaweeds have been reported to have mosquitocidal properties [15,16,17]. Recently, the larvicidal activity of extracts and compounds of 30 seaweed species was described in the review of Yu et al [18].…”

Abstract:The ever-increasing threat from infectious diseases and the development of insecticide resistance in mosquito populations drive the global search for new natural insecticides. The aims of this study were to evaluate the mosquitocidal activity of the extracts of seaweed Bryopsis pennata against dengue vectors Aedes aegypti and Aedes albopictus, and determine the seaweed's toxic effect on brine shrimp nauplii (as a non-target organism). In addition, the chemical compositions of the active larvicidal extract and fraction were analyzed by using liquid chromatography-mass spectrometry (LC-MS). Chloroform extract exhibited strong ovicidal activity (with LC50 values of 229.3 and 250.5 µg/mL) and larvicidal activity against Ae. aegypti and Ae. albopictus. The larvicidal potential of chloroform extract was further ascertained when its A7 fraction exhibited strong toxic effect against Ae. aegypti (LC50 = 4.7 µg/mL) and Ae. albopictus (LC50 = 5.3 µg/mL). LC-MS analysis of the chloroform extract gave a tentative identification of 13 compounds; Bis-(3-oxoundecyl) tetrasulfide was identified as the major compound in A7 fraction. Methanol extract showed strong repellent effect against female oviposition, along with weak adulticidal activity against mosquito and weak toxicity against brine shrimp nauplii. The mosquitocidal results of B. pennata suggest further investigation for the development of effective insecticide.

“…Aedes aegypti, the primary carrier for viruses that cause dengue and dengue hemorrhagic fever and yellow fever, are widespread over large areas of the tropics and subtropics. 16 The prevention of mosquito breeding through the use of larvicides is the most effective way to fight with this mosquito importunation. Synthetic insecticides have been used as larvicide in several countries for the last 30 years.…”

Objective: Aedes aegypti is the vector responsible for the transmission of dengue fever, and it is a cosmotropical species that proliferates in the water stagnant areas near the houses.Therefore, it is necessary to find new bioinsectiside which is expected to have larvacidal effects. The aims of this study are to evaluate extracts of Pinus merkusii tree bark for efficacy against Aedes aegypti larvae. Methods: This experiment using a completely randomized design with 8 treatment groups. Each group contained five times repetition using 20 third instar larvae of Aedes aegypti with concentrations of Pinus merkusii tree bark extract are 0, 10, 20, 40. 80, 160, 320, 640 ppm. Larval mortality was observed for 24 h and LC50 was analyzed using Probit analysis. Results: Ethanol extract of Pinus merkusii tree bark extract showed highest larval mortality against the larvae of Aedes aegypti with LC50 = 96.3 ppm; LC90 = 298.4 ppm after 12 h, and LC50 = 58.4 ppm; LC90 = 125.7 ppm after 24 h. Conclusion: These findings suggest that extracts from Pinus merkusii tree bark have larvacidal effect that can be exploited in development of new bioinsecticides.
