Two new compounds: 3-β,15-α,23,28-tetrahydroxyolean-12-en-3-O-arabinopyaranoside and 3-β,23,28-trihydroxy-olean-12-en-3-O-β-D-glucopyranoside were isolated from the aerial parts of Ammania auriculata along with the known compounds kaempferol, β-sitosterol-3-O-β- D-glucoside, 2-α,3-β,23-trihydroxyolean-12-en-28-oic acid-28-O-β-D-glucopyranoside, quercetin, kaempferol-3-O-α-L-arabinofuranoside, k...

Five new triterpenoid saponins, fargosides A, B, C, D, and E, were isolated from the roots of Holboellia fargesii. The structures of fargosides A-E were elucidated on the basis of chemical and physicochemical evidence and found to be 3beta,20alpha-dihydroxy-29-norolean-12-en-28-oic acid 3-O-beta-D-xylopyranosyl-(1-->2)-beta-D-glucopyranoside (1), 3beta,20alpha,24-trihydroxy-29-norolean-12-en-28...

A new triterpene saponin, named as 23-hydroxy-3alpha-[O-alpha-L-1C4-rhamnopyranosyl-(1"-->4')-O-alpha-L-4C1-arabinopyranosyl-oxy]olean-12-en-28-oic acid O-alpha-L-1C4-rhamnopyranosyl-(1""'-->4"")-O-beta-D-4C1-glucopyranosyl-(1""-->6"')-O-beta-D-4C1-glucopyranosyl ester (9), was isolated from the leaves of Bauhinia variegata Linn. In addition, six flavonoid compounds along with two cinnamic acid...

CRYSTALS OF THE TITLE COMPOUND (SYSTEMATIC NAME: 3β-hy-droxy-olean-12-en-28-oic acid ethanol monosolvate), C(30)H(48)O(3)·C(2)H(5)OH, were obtained from unsuccessful co-crystallization trials. The asymmetric unit contains two symmetry-independent oleanolic acid mol-ecules, as well as two ethanol solvent mol-ecules. Inter-molecular O-H⋯O hydrogen bonds stabilize the crystal packing. In the olean...

In recent years, the scientific interest and particularly economic significance of halophytic plants has been highly demanding due to medicinal nutraceutical potential its bioactive compounds. A xero-halophyte Bassia indica is deemed be a very cheap source natural entities without chemical or biological investigation. this context, new acylated flavonol tetraglycoside, kaempferol-3-O-?-d-glucop...

Cirsium arvense (L.) Scop., commonly known as creeping thistle, is a weed of Asteraceae. This study was undertaken to explore various phytoconstituents present in flower this weed. To achieve goal, the dried flowers were soaked methanol for one week and filtered. methanolic extract subjected GC-MS analysis 7 compounds identified. These included olean-12-en-3-ol, acetate, (3β)- (63.87%), lanosta...

In this paper, chemical constituents from the stems of Salacia chinensis L. (Celastraceae) and evaluating their a-glucosidase inhibitory activity were reported. Our study provides more information to Vietnamese medical plants database. addition, our contributes search for effective inhibitors. Four olean-type triterpenoids isolated CHCl3- soluble fraction collected in Dong Nai Province. These c...
