The Shuanghuanglian formula (SF) is a famous antimicrobial and antiviral traditional Chinese medicine that is made of Lonicera japonica Thunb., Scutellaria baicalensis Georgi, and Forsythia suspensa (Thunb.) Vahl. According to the Chinese Pharmacopoeia, the SF is commonly administered OBJECTIVE
To investigate the chemical constituents from the ethanol extract of the stems of Lonicera japonica.
METHODS
The constituents were isolated and purified by repeated column chromatography on silica gel, Sephadex LH-20 and MCI HP-20. Their structures were identified by phsicochemical
A method which involves combination of centrifugal ultrafiltration sampling with high-performance liquid chromatography coupled with diode array detection and mass spectrometry (HPLC-DAD-MS) analysis was established for screening bioactive compounds binding to calf thymus deoxyribonucleic acid
OBJECTIVE
To investigate the chemical constituents of the dried buds of Lonicera confusa.
METHODS
Chromatography and spectral analysis were respectively used to isolate and identify the constituents.
RESULTS
Seven compounds were isolated from the dried buds of L. confusa, and identified as rutin,
The screening and analysis of bioactive components in traditional Chinese medicines (TCMs) is very important not only for the quality control of Chinese herbs but also for elucidating the therapeutic principles. This study developed a new method for screening and analyzing bioactive compounds from
In this work, the n-butanol extract from leaves of Lonicera japonica Thunb. (L. japonica) was reacted with DPPH and subjected to a HPLC analysis for the guided screening antioxidants (DPPH-HPLC experiments). Then, nine antioxidants, including flavonoid glycosides and caffeoylquinic acid derivatives,
A rapid and simple method has been developed for the screening and identification of natural antioxidants of Flos Lonicerae Japonicae (FLJ), derived from the flower buds of Lonicera japonica. The hypothesis is that upon reaction with 1,1-diphenyl-2-picrylhydrazyl (DPPH), the peak areas (PAs) of
Lonicera japonica Thunb. is an economically important species of honeysuckle belonging to the Caprifoliaceae family. All aerial parts of L. japonica (leaf, flower bud, flower, and caulis) are used as herbal remedies in traditional Chinese medicine. The application of plant metabolomics
