Lawsonia inermis L., or henna leaves, are usually used to treat wounds on the skin. contain naphthoquinones, flavonoids, tannins, and saponins. The antibacterial activity of L. leaf extract in various solvents has been extensively studied. However, which component is responsible for still unknown. This study was intended investigate effect fractions against Staphylococcus aureus discover chemic...

Abstrak Seaweed belongs to the group of natural antioxidants, these antioxidants are able counteract free radicals. Secondary metabolites that include alkaloids, flavonoids, phenolic compounds, steroids, and terpenoids carotenoids. This study aims identify test radical scavenging 2,2 diphenyl-1-pkrylhydrazyl (DPPH) from crude extract macroalgae symbiont pigment Turbinaria conoides originating c...

The steam-distilled fraction of the aerial parts of Erigeron speciosus (Lindl) DC was tested for activity against strawberry plant pathogenic fungi Botrytis cinerea Pers ex Fr, Colletotrichum acutatum Simmonds, C fragariae Brooks, C gloeosporioides (Penz) Penz & Sacc, and the intermediate host snail Planobdella trivolvis that harbors the trematode, Bolbophorus confusus, that infests and causes ...

TLC bioautography using precoated glass thin-layer plates impregnated with benomyl or carbendazim (MBC), and Cladosporium herbarum as a test fungus was evaluated as a facil way to detect plant secondary m etabolites antidoting against benzimidazole fungicides. In ad­ dition to emodin and a-tocopherol from Polygonum sachalinense, three phenolics, 3,5-dihydroxy-4-methylstilbene and 5-methoxy-6,7-...

Vitamin B12 contents in the edible cyanobacterium Nostoc flagelliforme, also known as hair vegetable, were assayed using a microbiological method. We detected high vitamin B12 contents in samples of naturally grown cells (109.2 ± 18.5 μg/100g dry weight) and cultured cells (120.2 ± 53.6 μg/100g dry weight). However, commercially available hair vegetable samples, which comprised fake substitutes...
