Chemical constituents from the rhizomes of ligularia vellerea was written by Zhao, Yuan;Yang, Ru;Wang, Cai-fang;Zhao, Yu;Zhang, Zhen-zhong. And the article was included in Tianran Chanwu Yanjiu Yu Kaifa in 2014.Product Details of 1731-94-8 The following contents are mentioned in the article:
18 Compounds were isolated and purified from the rhizomes of Ligularia vellerea. Their structures were determined on the basis of physiochem. properties and spectroscopy anal. as furanoeremophilan-14β, 6α-olide (1), β-sitosterol (2), tiglic acid (3), palmitic acid (4), nonadecanoic acid Me ester (5), eremophil-7 (11)-en-12, 8α (14β, 6α)-diolide (6), 8β-methoxy-eremophil-7 (11)-en-12, 8α (14β, 6α)-diolide (7), 1-O-palmitoylglycerol (8), 8β-hydroxy-eremophil-7 (11)-en-12, 8α (14β, 6α)-diolide (9), p-hydroxycinnamic acid Me ester (10), phydroxyacetophenone (11), umbelliferone (12), 3, 4-dihydroxyacetophenone (13), daucosterol (14), 1, 5-dicaffeoylquinic acid (15), p-hydroxycinnamic acid (16), caffeic acid (17), and aesculetin (6, 7-dihydroxycoumarin) (18). Compounds 4-5, 8, 10, 13, 15 and 17, 18 were firstly obtained from Ligularia vellerea. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Product Details of 1731-94-8).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Product Details of 1731-94-8
