Visenia (Paliasa). Isolation compound has been done by maceration, fractionation, and purification. The molecular structure was determined by IR spectroscopy, NMR 1D and 2D (1H-NMR, 13C-NMR, HSQC and HMBC). Isolate formed yellow paste (83.4 mg) with melting point of 156-158 °C. The λ maks data on the UV-Vis spectrum of 333.80 nm (3.795) indicate compound has a long conjugated double bond. Data IR vmax cm-1 for groups as follows: 3327 (-OH), 2933 (C-H aliphatic), 1653 (C=O amide), 1593 (olefin). The data of NMR 1,2D show that this compound contains 18 carbon atoms, consisting of: 1 methyl, 1 methylene, 11 metin and 5 carbon quartener. Metin carbon consists of 2 alkene protons (olefins), 7 aromatic protons, and 1 alkyl alcohol (δC 72.58 ppm). NMR data also shows that one quartener carbon as C = O amide group (δC 166.92 ppm) and one methoxy (δC 55.35 ppm). The (R)-N-trans-feruloyloctopamine is the first compound found in the genus Melochia.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Alkyl alcohols,Amide groups,Aromatic protons,Carbon atoms,Conjugated double bonds,Methoxy,NMR data,UV-Vis spectrum[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1742-6596/1341/3/032021[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
