Asenjonamides A–C, antibacterial metabolites isolated from Streptomyces asenjonii strain KNN 42.f from an extreme-hyper arid Atacama Desert soil
Bio-guided fractionation of the culture broth extract of Streptomyces asenjonii strain KNN 42.f recovered from an extreme hyper-arid Atacama Desert soil in northern Chile led to the isolation of three new bioactive β-diketones; asenjonamides A–C (1–3) in addition to the known N-(2-(1H-indol-3-yl)-2-oxoethyl)acetamide (4), a series of bioactive acylated 4-aminoheptosyl β-N-glycosides; spicamycins A–E (5–9), and seven known diketopiperazines (10–16). All isolated ... إقراء المزيد

In vitro Propagation and Essential Oils Composition with Cytotoxicity of Daucus capillifolius Gilli (Apiaceae)

In vitro Propagation and Essential Oils Composition with Cytotoxicity of Daucus capillifolius Gilli (Apiaceae)
Abstract : Micropropagation and callus culture of Daucus capillifolius Gilli (Apiaceae) were successfully established in Murashige and Skoog(MS) solid medium enriched with different plant growth regulators. The combination of NAA (1mg/L) + BAP (0.1mg/L) was found to be the optimum for both organogenesis and embryogenesis. The compositions of essential oils obtained from wild fruits, cultivated fruits and callus culture were ... إقراء المزيد

Chemical and Cytotoxic Investigation of Non-Polar Extract from Ceiba Pentandra (L.) Gaertn.: A Study Supported by Computer Based Screening
Nowadays, the discovery of new drugs from natural sources is increasing dramatically. Recently, the sight is directed toward ornamental plants due to their sustainability. In this study, we are reporting on the gas chromatography profile of fatty acids, other related lipids, and hydrocarbons of the non-polar methylene chloride (MC) fraction of the extract of the ornamental tree Ceiba pentandra (L.) ... إقراء المزيد

Harpulliasides A and B: Two new benzeneacetic acid derivatives from Harpullia pendula
Two new benzeneacetic acid derivatives, harpulliaside A (1) and harpulliaside B (2), together with five known flavonoid glycosides; quercetin-3-O-b-D-glucoside (3), kaempferol-3-O-b-D-glucoside (4),kaempferol-3-O-b-D-glucopyranosyl-(1-2)-a-L-rhamnopyranoside (5), kaempferol-3-O-b-D-glucopyranosyl -( 1 !4)-a-L-rhamnopyranoside (6), and kaempferol-3-O-b-D-apiofuranosyl-(1 !2)-b-D-glucopyranoside (7) were isolated and characterized for the first time from the leaves of Harpullia pendula. The structures of these compounds were established by 1D and 2D NMR experiments and ... إقراء المزيد

Noncyanogenic Cyanoglucoside Cyclooxygenase Inhibitors from Simmondsia chinensis
ABSTRACT: Two new non-cyanogenic cyanoglucoside dimers, simmonosides A and B (1 and 2), were identified from the aqueous extract of jojoba (_Simmondsia chinensis_) leaves. 1 and 2 are the first examples of non-cyanogenic cyanoglucoside dimers containing a unique four-membered ring, representing novel dimerization patterns at α,β-unsaturated carbons of a nitrile group in 1 and γ,δ-unsaturated carbons in 2. Their structures ... إقراء المزيد
