Analysis of triterpenoids and phytosterols in vegetables by thin-layer chromatography coupled to tandem mass spectrometry.

J. Chromatogr. A. 1381 , 229-38, (2015)

Three TLC methods were used for an initial screening of some common plant triterpenoids and phytosterols in cuticular wax extracts of different vegetables (zucchini, eggplant, tomato, red pepper, mangold, spinach, lettuce, white-colored radicchio di Castelfra...

Functional Characterization of Cucurbitadienol Synthase and Triterpene Glycosyltransferase Involved in Biosynthesis of Mogrosides from Siraitia grosvenorii.

Plant Cell Physiol. 56 , 1172-82, (2015)

Mogrosides, the major bioactive components isolated from the fruits of Siraitia grosvenorii, are a family of cucurbitane-type tetracyclic triterpenoid saponins that are used worldwide as high-potency sweeteners and possess a variety of notable pharmacological...

Triterpene glycosides and other polar constituents of shea (Vitellaria paradoxa) kernels and their bioactivities.

Phytochemistry 108 , 157-70, (2014)

The MeOH extract of defatted shea (Vitellaria paradoxa; Sapotaceae) kernels was investigated for its constituents, and fifteen oleanane-type triterpene acids and glycosides, two steroid glucosides, two pentane-2,4-diol glucosides, seven phenolic compounds, an...

β-Amyrin biosynthesis: the critical role of steric volume at C-19 of 2,3-oxidosqualene for its correct folding to generate the pentacyclic scaffold.

Org. Lett. 16(13) , 3548-51, (2014)

The effect of the steric volume at C-19 of (3S)-2,3-oxidosqualene 1 on the polycyclization reaction by β-amyrin synthase was examined. The substrate analogs, in which the methyl group at C-19 of 1 was substituted by an ethyl group and hydrogen atom, were conv...

Nutritional evaluation and health promoting activities of nuts and seeds cultivated in Greece.

Int. J. Food Sci. Nutr. 64(6) , 757-67, (2013)

Available data suggest that genetic as well as environmental factors may influence nuts and seeds nutrients content. In this context nuts and seeds cultivated in Greece were studied. Macronutrients content was in agreement with that from other areas. Total ph...

Antidiabetic property of Symplocos cochinchinensis is mediated by inhibition of alpha glucosidase and enhanced insulin sensitivity.

PLoS ONE 9(9) , e105829, (2014)

The study is designed to find out the biochemical basis of antidiabetic property of Symplocos cochinchinensis (SC), the main ingredient of 'Nisakathakadi' an Ayurvedic decoction for diabetes. Since diabetes is a multifactorial disease, ethanolic extract of th...

Inhibitor selectivity between aldo–keto reductase superfamily members AKR1B10 and AKR1B1: Role of Trp112 (Trp111)

FEBS Lett. 587(22) , 3681-6, (2013)

• Crystal structures of AKR1B10 holoenzyme. • Trp112 side-chain flipping in AKR1B10 explains non-selectivity of AKR1B1 inhibitors. • Native Trp112 side-chain orientation is critical for selective AKR1B10 inhibitors.

The supplementation of Korean mistletoe water extracts reduces hot flushes, dyslipidemia, hepatic steatosis, and muscle loss in ovariectomized rats.

Exp. Biol. Med. (Maywood.) 240(4) , 477-87, (2015)

Since Korean mistletoe (Viscum album) has been used for alleviating metabolic diseases, it may also prevent the impairment of energy, glucose, lipid, and bone metabolisms in an estrogen-deficient animal model. We determined that long-term consumption of Korea...

Comparative analysis of CYP93E proteins for improved microbial synthesis of plant triterpenoids.

Phytochemistry 108 , 47-56, (2014)

Cytochrome P450-dependent monooxygenases (P450s) belonging to the CYP93E subfamily catalyze the C-24 oxidation of the triterpene backbone during the biosynthesis of triterpenoid saponins, which are bioactive plant natural products. In our attempts to produce ...

Suppression of inflammatory cascade is implicated in methyl amooranin-mediated inhibition of experimental mammary carcinogenesis.

Mol. Carcinog. 53(12) , 999-1010, (2014)

Breast cancer represents the second leading cause of cancer-related deaths among women worldwide and preventive therapy could reverse or delay the devastating impact of this disease. Methyl-amooranin (methyl-25-hydroxy-3-oxoolean-12-en-28-oate, AMR-Me), a nov...
