In this paper, CN-DPA was prepared as an effective colorimetric and fluorescent probe for copper ions (Cu(2+)) in aqueous solution. It exhibits good sensitivity and selectivity for Cu(2+) over other metal ions both in aqueous solution and on a simple colorimetric paper-made test kit. Upon addition of Cu(2+), a remarkable color change from purple to(More)
A disulfide linked naphthalimide dimer probe was designed for mercury ion (Hg2+) recognition in this work. The recognition was based on the strong affinity of mercury for sulfur. The experimental results revealed that the probe exhibited high selectivity and sensitivity toward Hg2+ in comparison to other metal ions via a turn-on and reversible response to(More)
A 4-aminonaphthalimide-based ratiometric fluorescent probe 1 employing the internal charge transfer (ICT) mechanism was designed and synthesized to detect bovine serum albumin (BSA). The interaction of 1 and BSA was investigated by fluorescence and UV-vis absorption spectroscopy. Upon treatment with BSA, the probe successfully exhibited a ratiometric(More)
Exploration of environmentally friendly light-emitting devices with extremely low weight has been a trend in recent decades for modern digital technology. Herein, we describe a simple suction filtration method to develop a transparent and photoluminescent nanocellulose (NC) paper, which contains ZnSe quantum dot (QD) with high quantum yield as a functional(More)
The essential oil from different parts of Datura metel L. were extracted using hydrodistillation and GC-MS was used to analyse the essential oil. The main components of flowers were ketone (23.61%) and ethyl palmitate (15.84%). The main components of leaves were ketone (18.84%) and phytol (18.71%). Ketone (39.45%) and phytol (31.32%) were the major(More)
INTRODUCTION Aralia elata leaves are known to have several biological activities, including anti-arrythmia, antitumor, anti-inflammatory, anti-fatigue, antimicrobial and antiviral effects. Our previous study found that triterpenoid saponins from the leaves of A. elata had antitumor effects. Quantification of the triterpenoids is important for the quality(More)
Aralia elata (Miq.) Seem. is widely distributed in Oriental countries, such as Korea, Japan, and China [1]. The young A. elata leaves are cultivated as a vegetable crop, especially in the spring. Its barks and root cortexes are widely used in folk medicine for the treatment of diabetes, gastric ulcer, hepatitis, and rheumatoid arthritis [2]. Several(More)
Anemarrhena asphodeloides processed by salt and raw product was compared including both chemical composition and laxative function in order to find the possible active substance to cure constipation. Processed and raw Anemarrhenae laxative effect on experimental constipation models was observed as well as chemical composition using UPLC-MS technology and(More)
A rapid, sensitive, and reliable analytical ultra performance liquid chromatography with tandem mass spectrometry method was developed for the simultaneous determination of Aralia-saponin IV, 3-O-β-d-glucopyranosyl-(1→3)-β-d-glucopyranosyl-(1→3)-β-d-glucopyranosyl oleanolic acid 28-O-β-d-glucopyranoside, Aralia-saponin A and Aralia-saponin B after the oral(More)
OBJECTIVE We explored the composition and diversity of archaea in a cold sulfur spring water in Xinjiang earthquake fault zone. METHODS Environmental total DNA was extracted directly with enzymatic lysis method from a cold sulfur spring water. We constructed clone library of 16S rRNA gene amplified with archaeal-specific primers. A total of 115 positive(More)
