Flavonoids with hepatoprotective activity from the leaves of Cleome viscosa L.
TLDR
One new flavonol glycoside named visconoside C is named and the structures were elucidated by IR, UV, HR-ESI-MS and NMR experiments and hepatoprotective activities using HepG2 human hepatoma cell line were measured.
Sesamin suppresses aging phenotypes in adult muscular and nervous systems and intestines in a Drosophila senescence-accelerated model.
TLDR
It is proposed that sesamin exerts anti-aging effects in the muscles, brain and midgut by inducing antioxidative and DNA repair genes, resulting in extended lifespan in flies.
A new dihydrofurocoumarin from the fruits of Pandanus tectorius Parkinson ex Du Roi
TLDR
The isolated compounds showed better α-glucosidase inhibitory activity than the standard drug acarbose and their structures were elucidated by HR–ESI–MS, NMR 1D and 2D experiments and comparison with previous reported data.
A new aldehyde compound from the fruit of Pandanus tectorius Parkinson ex Du Roi
TLDR
From the fruit of Pandanus tectorius Parkinson ex Du Roi, one new and six known aldehyde compounds were isolated by various chromatography methods and showed better α-glucosidase inhibitory activity than the standard drug acarbose.
Two new phenolic compounds from the lichen Parmotrema cristiferum growing in Vietnam.
Two new phenolic compounds, cristiferides A-B (1-2) together with six known compounds, 2,4-dihydroxyphthalide (3), lecanoric acid (4), orsellinic acid (5), 5-chloroorsellinic acid (6), methyl
New C20-gibberellin diterpene from the leaves of Schefflera sessiliflora De P. V.
TLDR
From the leaves of Schefflera sessiliflora De P. V., one new C20-gibberellin diterpene 2β, 12β,12β-dihydroxy gibb Berellin and three known compounds, trans-tiliroside, 5-p-trans-coumaroylquinic acid, were isolated for the first time by various chromatography methods.
Triterpene saponins with α-glucosidase inhibition and cytotoxic activity from the leaves of Schefflera sessiliflora
TLDR
Two new triterpene saponins including one oleanane- type saponin, named scheffleraside C and one lupane-type saponine D, together with six known triterPene sap onins, were isolated by various chromatography methods and evaluated against MCF-7 human breast cancer cell lines.
Limonoid from the rhizomes of Luvunga scandens (Roxb.) Buch. Ham
TLDR
The chemical constituents of the rhizomes of Luvunga scandens and their chemical structures were elucidated by IR, UV, HR-ESI-MS, NMR 1D and 2D experiments and compared with literatures.
Investigation of Chitosan Nanoparticles Loaded with Protocatechuic Acid (PCA) for the Resistance of Pyricularia oryzae Fungus against Rice Blast
TLDR
The results suggested that CSNP loaded with PCA could be a potential compound for eradication of Pyricularia oryzae and that further testing on in vitro rice plants is recommended to reaffirm this possibility.
