Abstract:
The triterpene saponin fraction was isolated from &lt;em&gt;Trigonella monspeliaca&lt;/em&gt; tops. It consisted of ten saponosides, three of which were determined to be medicagenic acid glycosides, the other seven - soyasapogenol glucosides. Acid hydrolysis of the saponin fraction yielded medicagenic acid, soyasapogenol B and its artifacts soyasapogenol C, D and F. These data consitute the first report on the occurence of medicagenic acid and soyasapogenol glycosides in the genus &lt;em&gt;Trigonella&lt;/em&gt;.

Abstract:
Abstract Alkaline hydrolysis was performed on a series of different vegetable oils. The unsaponifiable lipid matter was extracted with ethyl ether, and the class of 4,4-desmethylsterols (sterols) plus the triterpene diols (diols) erythrodiol, uvaol, and betulinol were isolated by thin-layer chromatography. A validated method using the acetate derivatives of sterols instead of their silyl ethers is presented. The acetate derivatives were analyzed by high resolution gas chromatography (HRGC). Retention time, precision, recovery studies, and absolute response factors were calculated for these est

Abstract:
Autophagy is an important self-degradative mechanism that plays a key role in treating neurodegeneration diseases. This research aimed at discovering bioactive compounds from Aster koraiensis. A new triterpene saponin, astersaponin I (1), was isolated from the EtOH extract of A. koraiensis. The structure of 1 was characterized by spectroscopic methods, ECD calculation, and acid hydrolysis. The biochemical analysis showed that compound 1 significantly increased the expression of microtubule-associated protein 1A/1B light chain 3B (LC3-II) expression in SH-SY5Y cells, which indicates the inducti

Full text
Abstract:
Several pentacyclic triterpenoid metabolites of plant origin are inhibitors of hydrolysis of both synthetic peptide substrates and elastin by human leucocyte elastase (HLE). Ursolic acid, the most potent of these compounds, has an inhibition constant of 4-6 microM for hydrolysis of peptide substrates in phosphate-buffered saline. With tripeptide and tetrapeptide substrates, the inhibition is purely competitive, whereas with a shorter dipeptide substrate the inhibition is non-competitive, suggesting that ursolic acid interacts with subsite S3 of the extended substrate-binding domain in HLE, but

Abstract:
Two new and five known acylated triterpene glycosides were isolated from the MeOH extract of the roots of Polygala tenuifolia. Based on extensive spectroscopic analysis, including 2D NMR experiments, and the results of alkaline hydrolysis, the structures of the new compounds were assigned as 3β-[(β-D-glucopyranosyl)oxy]–2β,27-dihydroxyolean-12-ene-23,28-dioic acid 28- O-β-D-apiofuranosyl-(1→3)-[β-D-galactopyranosyl-(1→4)-β-D-xylopyranosyl-(1→4)]-α-L-rhamnopyranosyl-(1→2)-3- O-( E)-3,4,5-trimethoxycinnamoyl-β-D-fucopyranosyl ester (1) and 3β-[(β-D-glucopyranosyl)oxy]–2β,27-dihydroxyolean-12-ene

Abstract:
The raw material being studied is the woolen fat of the sheep of the Edilbay fine-fleece and Kazakh arkharomeric fine-fleece, which is excreted when washing wool in primary wool processing plants (PWP) in the regions of Kazakhstan, such as Semipalatinsk, Aktyubinsk, Zhambyl and Tokmak. Earlier we obtained anhydrous lanolin from the fat of various factories of the PWP. In both cases, positive results were obtained and a certificate of compliance of anhydrous lanolin FS RK was obtained. In terms of its chemical composition, wool fat is a mixture of C10-C16 carboxylic acid esters with aliphatic,

Furthermore, 2, 13-dihydroxy-mulin-11-ene was obtained using a basic hydrolysis of the first compound. Two diterpenes reported for other Azorella species have also been found, namely mulinolic acid and 13β-hydroxyazorellane, as well as the triterpene lactone of ursolic acid, quercetin, and 7-hydroxycoumarin.

Abstract:
Previously, the authors conducted phytochemical investigations of the aerial parts of Larrea tridentata and reported triterpene glycosides and lignan derivatives. In continuation of the preceding studies, 17 lignans and lignan glycosides (1–17) were isolated, including seven new compounds (1–7). Herein, the structure of the new compounds was determined based on spectroscopic analysis and enzymatic hydrolysis. The cytotoxicity of 1–17 against HL-60 human promyelocytic leukemia cells was examined. Compounds 4–11 and 14–16 were cytotoxic to HL-60 cells, with IC50 values in the range of 2.7–17 μM.

Betulinic acid derivatives exhibit different biological activity against diversified targets, such as anticarcinogenic activity in experimental animals, anti-HIV, antihyperglycemia, and anti-inflammatory in humans. In this work, we investigated the synthetic procedure of 24-nor-3-oxo-20(29)-lupen-28-oic acid (1) derivatives. Starting from compound 1 and L-leucine methyl ester, we proceeded with amidification, reduction, and hydrolysis under basic conditions. Finally, three hybrid compounds were successfully synthesised and elucidated with spectral means.

The total synthesis of lupeol was one of the crowning achievements of the Robinson annulation/ reductive alkylation approach to stereocontrolled polycarbocyclic construction developed by Gilbert Stork (J. Am. Chem. Soc. 1971, 93, 4945). It is a measure of the progress of organic synthesis since that time that E. J. Corey of Harvard University could devise (J. Am. Chem. Soc. 2009, 131, 13928) an enantioselective synthesis of (+)-lupeol 3 that could be carried out by a single colleague. The key step in the synthesis was the Lewis acid–mediated cyclization of 1 to 2.
