[Monitoring novel ovarian carcinoma associated genes using cDNA expression microarray].
OBJECTIVE: To explore the gene expression pattern of sample of human ovarian carcinoma. METHOD: The difference in gene expression between normal and neoplastic human ovarian tissues were investigated, we described the assembly and utilization of a 512 member cDNA microarray. RESULT: Thirty-seven genes expressed in ovarian cancer were screened out, 14 genes were up-regulated, 23 genes were down-regulated. CONCLUSION: cDNA microarray for analysis of gene expression pattern is an effective method to identify novel ovarian cancer associated genes.

[Study on chemical constituents of rhizome of Anemone raddeana].
AIM: To investigate the chemical constituents of the rhizome of Anemone raddeana Regel, so as to find new active compounds. METHODS: The ethanol extracts of the rhizome of Anemone raddeana were obtained by silica column, HPLC. The structures of the compounds were elucidated by means of physico-chemical method and spectral analysis (IR, FAB-MS, 1HNMR, 13CNMR, DEPT, 1H-1H COSY, HMQC, HMBC). RESULTS: Nine compounds were isolated and identified as 27-hydroxyolean-12(13)-en-28-oic acid-3-0-alpha-L-rhamnopyranosyl-(1-->2)-alpha-L-arabinopyranoside (1), eleutheroside K (2), Oleanolic acid-3-O-alpha-L-rhamnopyranosyl-(1-->2)-[beta-D- glucopyranosyl-(1-->4)]-alpha-L-arabinopyranoside (3), betulin (4), betulic acid (5), acetyloleamolic acid (6), evonymitol (7), oleamolic acid (8) and diosgenin (9). CONCLUSION: Compound 1 is a new compound, named raddeanoside 12. Compounds 3-7 were isolated from this plant for the first time.
