A robust, selective and highly sensitive chemiluminescent （CL） platform for protein assay was presented in this paper. This novel CL approach utilized rolling circle amplification （RCA） as a signal enhancement technique and the 96-well plate as the immobilization and separation carrier. Typically, the antibody immobilized on the surface of 96-well plate was sandwiched with the protein target and the aptamer-primer sequence. This aptamer-primer sequence was then employed as the primer of RCA. Based on this design, a number of the biotinylated probes and streptavidin-horseradish peroxidase （SA-HRP） were captured on the plate, and the CL signal was amplified. In summary, our results demonstrated a robust biosensor with a detection limit of 10 fM that is easy to be established and utilized, and devoid of light source. Therefore, this new technique .will broaden the perspective for future development of DNA-based biosensors for the detection of other protein biomarkers related to clinical diseases, by taking advantages of high sensitivity and selectivity.

Objective Tu Jia ethnomedicine is a unique medical system inherited and adhibited by Tu Jia minority living in central-south China. Panax japonicus C. A. Mey.(Bai San Qi,白三七) is recognized as an effective and rare medicinal plant to treat weakness, fatigue and rheumatism in Tu Jia ethnomedicine. This paper is to discover more substance evidence for the application of Tu Jia ethnomedicine. Methods Column chromatography and preparative high performance liquid chromatography (HPLC) was applied for isolation and purification;1H-NMR, 13C-NMR, 1H-1H COSY, HSQC and HMBC NMR spectra were applied for structure identification;Methyl thiazolyl tetrazolim (MTT) assays were applied for cytotoxicity evaluation. Results Totally 12 known compounds were isolated by column chromatography and preparative HPLC from rhizomes of Panax japonicus C. A. Mey.(Bai San Qi,白三七). Structures of these compounds were identified by their NMR spectra. All the 12 compounds were triterpenoid saponins. Five of them were oleanolic acid type, and the remaining 7 were dammarane type. Eleven compounds were assayed for their cytotoxic activity against Hep G2 human liver cancer cell lines and BGC-823 human gastric cancer cell lines. Three of the 11 showed relatively dominant cytotoxicity against these cell lines. Conclusions A total of 12 known compounds have been identified from Panax japonicus C. A. Mey.(Bai San Qi,白三七);NMR spectra of compounds with similar skeletons showed regular characteristics;3 compounds showed relatively dominant cytotoxicity against Hep G2 and BGC-823 cancer cell lines, and the result can be valued as weak while setting the taxol as a positive control.
