The leaf extract of Tectona grandis L.f. has shown potential as a 5α-reductase inhibitor, with two bioactive markers, namely (+)-eperua-8,13-dien-15-oic acid (1) and (+)-eperua-7,13-dien-15-oic (2), used for standardization. purpose this research was to investigate the in vitro skin penetration behavior 1 2 T. ethanolic solution ready-to-use propylene glycol (PG), secondly, determine their physicochemical properties, including partition coefficients solubility. appropriate vehicle study...
Peristrophe bivalvis (L.) Merr. (Acanthaceae family) has traditionally been used as a natural food colorant and in the treatment of various diseases. However, its biological activities—particularly anti-glycation anti-lipid peroxidation properties—as well development novel nanoemulsions incorporating crude P. leaf extracts for cosmetic applications, have not yet reported. The aim this study was to explore potential an active ingredient nanocosmetics. Various solvents, including deionized...
A new oxidized heptene, 7-benzoyloxy-4-hydroxy-1-ethoxy-2E,4Z-heptadiene-1,6-dione, namely siamheptene (1), together with eight known compounds (2-9), were isolated from the leaves of Uvaria siamensis. Their structures elucidated by detailed analysis spectroscopic (IR, 1D and 2D NMR) mass spectrometric data. Compound 9 is reported for first time genus. Siamheptene was evaluated cytotoxicity against HeLa (cervical cancer cells), A549 (lung Vero cells using MTT assay screened antibacterial...
Dendrobium sulcatum Lindl or “Ueang Jampa-Nan” (Orchidaceae family) is widely dis-tributed in Thailand and Laos. It classified the genus Dendrobium, which used both traditional Chinese medicine Ayurvedic for health enhancement anti-aging. The purpose of this study was to investigate phytochemical constituents bioefficacy stems, leaves flowers from D. cosmetic cosmeceutical applications. Phenolic flavonoid contents were tested evaluation. antioxidant (DPPH, FRAP ABTS assays), anti-lipid...
The leaves of Aquilaria spp. promote "physiological balance", and are "cardiotonic provide blood nourishment". In Asia, these increasingly consumed as tea claimed to benefits cardiovascular function, albeit without any scientific proof. Therefore, this study sought evaluate the action crassna leaf aqueous extract (AE) on vascular function smooth muscle cytotoxicity. AE a main constituent, mangiferin were investigated for their vasorelaxation rat mesenteric arteries aortae in vitro. Acute...
Tectona grandis has been reported for its composition of two 5α-reductase inhibitors, specifically (+)-eperua-8,13-dien-15-oic acid (1) and (+)-eperua-7,13-dien-15-oic (2). These compounds exhibit potential as markers, enabling the standardization leaf extracts during pre-formulation formulation development. This study examined effects solvent system, pH, temperature light on stability 1 2 in ethanolic extract PG with PEG-40 a solubilizer. The remaining amount at all test conditions was...
Andrographis paniculata (Burm. F.) Nees is a medicinal plant previously reported with broad-spectrum antivirals but the mode of inhibition remains elusive. The objective this study was to identify most active fraction from A. ethanol extract (APE, APE-2A, APE-2B and APE-2C) dry powder (APSP) against influenza A (H3N2), representing RNA viruses, herpes simplex virus-1 (HSV-1), DNA viruses. results showed that fractions APSP, APE, APE-2B, APE-2C directly neutralized HSV-1 (H3N2) when incubated...
Thermal degradation of verbascoside (VB) in Acanthus ebracteatus Vahl (AE) always affects its health benefit. Here the temperature effect on VB both AE extract and solid lipid nanoparticles (SLNs)-encapsulated was demonstrated using Arrhenius plot. The reaction rate constants were calculated for shelf life plotted to obtain pH–rate profiles. a first-order reaction. neutral alkaline solution faster than an acidic solution. extract-loaded SLNs more stable uncapped extract. 153 days with...
The aim of this study was to investigate the effects drying process preparations, solvent type, and different species Prunus spp. (European, Japanese, cherry plums) on bioactive properties (antioxidant, anti‐lipid peroxidation, anti‐tyrosinase, anti‐inflammatory activities) rutin content. Leaves fresh fruits plums were dried using a cold (vacuum freeze dryer at −105 ± 5°C) hot (hot air oven 50 0.5°C). plant material then extracted ethanol propylene glycol obtain ethanolic crude extracts...
The health benefits of the Aquilaria crassna Pierre ex Lecomte leaf extract (AE) make it very useful as an ingredient in food and pharmaceutical products. Iriflophenone 3,5-C-β-d-diglucoside (1), iriflophenone 3-C-β-d-glucoside (2) mangiferin (3) are bioactive compounds AE. We assessed stability AE by investigating thermal degradation kinetics shelf-life (t90%) 1, 2 3 using Arrhenius plot models studied their pH-rate profiles. results demonstrate that 1 were degraded, following a first-order...
