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)
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)
A selective and sensitive ultra-high performance liquid chromatography with tandem mass spectrometry method was developed and validated for the determination and pharmacokinetic study of (+)-8-hydroxypinoresinol-4'-O-β -D-glucopyranoside, prinsepiol-4-O-β-D-glucopyranoside, (+)-pinoresinol-4,4'-di-O-β-D-glucopyranoside, and (-)-massoniresinol(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)
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)
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)
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)
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)
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)
