We isolated and purified phenolic acids flavonoids from the ethanolic extract of Salvia plebeia using silica gel a Sephadex LH-20 column chromatography. Spectroscopy revealed compounds were caffeic acid, rosmarinic hispidulin, luteolin, jaceosidin, nepitrin, homoplantaginin, 6-hydroxyluteolin 7-O-glucoside, 6-methoxynaringenin naasanone, cosmosiin. Quantitative analyses, high-performance liquid chromatography coupled with UV (HPLC-UV), that major flavonoid S. was 7-O-glucoside (100.63 mg/g)...
Two new bidesmoside triterpenoid saponins which were identifed as 28-O-β-D-xylopyranosyl(1→3)-β-D-xylopyranosyl(1→4)-α-L-rhamnopyranosyl(1→2)-[α-L-rhamno-pyranosyl(1→3)]-β-D-fucopyranosyl gypsogenin 3-O-β-D-glucopyranosyl (1→2)-β-D-glucopyranosiduronic acid (C1) and 28-O-β-D-xylopyranosyl(1→4)-α-L-rhamnopyranosyl (1→2)-[α-L-rhamnopyranosyl(1→3)]-β-D-fucopyranosyl 3-O-β-D-gluco-pyranosyl(1→2)-β-D-glucopyranosiduronic (C2) isolated together with two known compounds from the seeds of Momordica...
Consistent ultraviolet B (UVB) radiation exposure results in dry skin, wrinkles, and melanogenesis. In this study, we investigated whether fish collagen peptide (NaticolⓇ) could inhibit photoaging oxidative stress skin exposed to UVB using cell animal models. We measured the hydration, histological observations, antioxidant activities, moisturizing-related factors, synthesis-related melanogenesis-related factors cells enzyme-linked immunosorbent assay, real-time polymerase chain reaction,...
Two new cucurbitane triterpenoids 1 and 2 were isolated, together with six known compounds, from the seeds of Momordica charantia L. The structures compounds determined to be 3-O-{[β-d-galactopyranosyl(1 → 6)]-O-β-d-galactopyranosyl}-23(R), 24(R), 25-trihydroxycucur-bit-5-ene (1), 3-O-[β-d-galactopyranosyl]-25-O-β-d-galactopyranosyl-7(R), 22(S), 23(R), 25-pentahydroxycucurbit-5-ene (2), respectively. Their elucidated by combination mass spectrometry, one- two-dimensional NMR experiments...
Bandiburichodang (BDC) is a new variety of Zea mays L. Total polyphenol content (TPC) assay and quantitative analysis ferulic acid (FA) were performed to determine the steaming, roasting conditions BDC kernels that lead highest content.TPC levels increased after under all conditions.TPC in samples steamed at 115 o C for 25 min 3.157 mg/g before roasted, 3.825 4.739 160 200 C, respectively.Whether roasted was relevant with TPC content.BDC extracted perform FA.Roasting temperature affected FA...
Four compounds were isolated from Salvia plebeia aerial parts.Silica gel open column chromatography with a gradient elution system was used to isolate and purify these compounds.Nuclear magnetic resonance spectroscopy mass for structural elucidation identification, while electronic circular dichroism confirm the absolute configuration.The structures determined be βsitosterol ( 1), (-)-1S,5S,8S,10R-1-acetoxy-8-hydroxy-2-oxoeudesman-3,7(11)-dien-8,12-olide (2), ursolic acid (3),...
