P. vietnamensis var. fuscidiscus, called “Yesanqi” in Chinese, is a new variety of P. vietnamensis, which was first found in Jinping County, the southern part of Yunnan Province, China. Compared with other Panax plants, this species contains higher content of ocotillol-type saponin, majonoside R2. Despite the pharmacological importance of ocotillol-type(More)
Recombinant fusion protein technology allows specific insecticidal protein and peptide toxins to display activity in orally-delivered biopesticides. The spider venom peptide δ-amaurobitoxin-PI1a, which targets insect voltage-gated sodium channels, was fused to the "carrier" snowdrop lectin (GNA) to confer oral toxicity. The toxin itself (PI1a) and an(More)
OBJECTIVE To explore breeding method and breed new varieties of Erigeron breviscapus. METHOD Superior individual were selected from natural outcrossing population of E. breviscapus, lines and strains were established and selected and compared. RESULT The scutellarin contents of two E. breviscapus strains of 2003-15 and 2003-6 through line breeding were(More)
For more than ten years, Erigeron breviscapus has been used for the treatment of cardiovascular and cerebrovascular diseases, it experienced the procedure from wild species to the cultivars, and the quality of drug was rapidly improved. In order to further promote the development of E. breviscapus planting industry, this paper analyzes the development(More)
A robust biodegradable hydrogel is constructed from two components containing G4.0 PAMAM and DOPA, which displays excellent interconnected porous 3D networks, higher mechanical strength, low and stable swelling and good biocompatibility. A mouse CSD model in vivo evidences that moderate bone-like tissue and extensive bony tissue are observed when the(More)
OBJECTIVE In order to establish new molecular markers and to design SSR primers,the SSR information was analyzed in the transcriptome of Pinellia ternata. METHODS The unigenes in transcriptome were filtered and then redundant sequences were removed by the tool of EST-trimmer and cross-match, respectively. Meanwhile, the non-redundant unigenes were(More)
A combination of Fourier transform infrared spectroscopy with chemometrics tools provided an approach for studying Marsdenia tenacissima according to its geographical origin. A total of 128 M. tenacissima samples from four provinces in China were analyzed with FTIR spectroscopy. Six pattern recognition methods were used to construct the discrimination(More)
OBJECTIVE Clone of sucrose synthase of Dendribium officinale and expression analysis, to provide the theory basis for research the relationship between polysaccharide synthesis of D. officinale and sucrose synthase activity. METHOD According to homologous sequence of sucrose synthase gene on GenBank, application the technology of RT-PCR and RACE, clone(More)
Fluorescence anisotropy (FA) is a reliable, sensitive, and robust assay approach for determination of many biological targets. However, it is generally not applicable for the assay of small molecules because their molecular masses are relatively too small to produce observable FA value changes. To address this issue, we report herein the development of a FA(More)
Dendrobium officinale Kimura et Migo is a traditional Chinese orchid herb that has both ornamental value and a broad range of therapeutic effects. Here, we report the first de novo assembled 1.35 Gb genome sequences for D. officinale by combining the second-generation Illumina Hiseq 2000 and third-generation PacBio sequencing technologies. We found that(More)
