Galloyl depsides of tyrosine from young leaves of Inga laurina.
Vetëm përdoruesit e regjistruar mund të përkthejnë artikuj
Identifikohuni Regjistrohu
In addition to the free protein amino acid l-tyrosine, the expanding young leaves of Inga laurina accumulate high concentrations of three new depsides, galloyl, m-digalloyl, and m-trigalloyl l-tyrosine (1, 2, and 3). The structures of these compounds were determined on the basis of their

Tyrosinase inhibitory p-coumaric acid from ginseng leaves.
Vetëm përdoruesit e regjistruar mund të përkthejnë artikuj
Identifikohuni Regjistrohu
By bioassay-guided fractionation using mushroom tyrosinase, p-coumaric acid was characterized as the principal tyrosinase inhibitor from the fresh leaves of Panax ginseng (Araliaceae). It inhibited the oxidation of L-tyrosine more strongly than that of L-3, 4-dihydroxyphenylalanine (L-DOPA) by this
Protein tyrosine phosphatase 1B (PTP1B)-inhibiting constituents from the leaves of Syzygium polyanthum.

Identifikohuni Regjistrohu
A methanol extract of the leaves of Syzygium polyanthum (Wight) Walp. afforded four new acylbenzene derivatives (1-4) together with seven known compounds (5-11). The structures of 1-11 were elucidated by extensive spectroscopic methods and comparison with the literature data. The new compounds 1-3
Tyrosinase inhibitor isolated from the leaves of Zanthoxylum piperitum.

Identifikohuni Regjistrohu
Two flavonols, quercetin (1) and quercitrin (2), were isolated from the leaves of Zanthoxylum piperitum. Their structures were established by UV, one- and two-dimensional NMR, and mass spectroscopic methods. Quercetin showed significant inhibition against mushroom tyrosinase with an IC50 value of
[One new truxillic amide compound from Abrus mollis leaves].

Identifikohuni Regjistrohu
The butanol extract part was extracted and isolated with water, alcohol and different organic solvents from Abrus mollis leaves. 6 compounds were isolated and purified using various column chromatographies and identified with the spectral techniques such as UV, MS, TLC, HPLC and NMR. The structures
Intracellular localization of labelling of tocopherols with [U-14C]tyrosine in Calendula officinalis leaves.
Vetëm përdoruesit e regjistruar mund të përkthejnë artikuj
Identifikohuni Regjistrohu
The content of tocopherols in the cellular subfractions of C. officinalis leaves from plants kept in the light and dark was investigated. In addition to the previously detected alpha-, gamma- and delta-tocopherols a small amount of 7-monomethyltocol was found in the chloroplasts, mitochondria and
Nitric oxide inhibits nitrate reductase activity in wheat leaves.
Vetëm përdoruesit e regjistruar mund të përkthejnë artikuj
Identifikohuni Regjistrohu
Nitrate reductase (NR), a committed enzyme in nitrate assimilation, is involved in the generation of nitric oxide (NO) in plants. In wheat leaf segments exposed to sodium nitroprusside (SNP) or S-nitrosoglutathione (GSNO), NR activity was significantly reduced to different degrees between 3 and 21

Identifikohuni Regjistrohu
The toxic metalloid arsenite has become a potential threat to rice growing regions leading to serious contamination in food chain. In the present study effect of different physiological concentration of arsenite that is toxic and triggers the molecular events were evaluated in rice seedlings. Along
ANGUSTIFOLIA Regulates Actin Filament Alignment for Nuclear Positioning in Leaves.

Identifikohuni Regjistrohu
During dark adaptation, plant nuclei move centripetally toward the mid-plane of the leaf blade; thus the nuclei in both the adaxial and abaxial sides become positioned at the inner periclinal walls of cells. This centripetal nuclear positioning implies that a characteristic cell polarity exists
A novel protein tyrosine phosphatase 1 B inhibitor-geranylated flavonoid from mulberry leaves ameliorates insulin resistance
Vetëm përdoruesit e regjistruar mund të përkthejnë artikuj
Identifikohuni Regjistrohu
Mulberry leaf is a common vegetable with a variety of beneficial effects, such as hypoglycemic activity. However, the underlying mechanism of its hypoglycemic effect have not been fully revealed. In this study, two flavonoid derivatives were isolated from mulberry leaves, a new geranylated flavonoid
Chitosan and chitin oligomers increase phenylalanine ammonia-lyase and tyrosine ammonia-lyase activities in soybean leaves.

Identifikohuni Regjistrohu
Phenylalanine ammonia-lyase (PAL, EC 4.3.1.5) and tyrosine ammonia-lyase (TAL, 4.3.1.), the key enzymes of the phenylpropanoid pathway, are inducible in response to biotic (such as chitin from fungal cell walls) and abiotic cues. Application of chitin and chitosan to soybean leaf tissues caused
