Inter simple sequence repeat (ISSR) markers were performed in order to analyse the genetic relation-ships of both taxa of Gardenia jasminoides var. radicans and G. jasminoides for. grandifora. Over the 88 fragments, only one locus (ISSR-11-05) was specific to G. jasminoides var. radicans and only one (ISSR-09-05) G. jasminoides for. grandiflora. Although G. jasminoides var. radicans showed low levels of alleles and Shannon's information index than G. jasminoides for. Grandiflora, however, there was not significant differences (p > 0.05). For both taxa the mean genetic diversity of natural populations was higher than that of cultivation populations. It was suggested that domestication processes via artificial selection do not have eroded the high levels of genetic diversity. ISSR markers were more effective in classifying natural populations of wild G. jasminoides in East Asia as well as cultivated G. jasminoides. The information about the phylogenetic relationship of G. jasminoides var. radicans and its closely related species is very valuable of the systematics of genus Gardenia, the origin of cultivated G. jasminoides, and future G. jasminoides breeding.

The phytochemical study of the underground parts of Gardenia jasminoides var. radicans Makino (Rubiaceae) led to the isolation of five coumarins. On the basis of spectroscopic evidences, the structures of these compounds were charaterized as ferulic acid(l), 5,8-di-(3-methyl-2,3-dihydroxybutyloxylpsoralen)(2), skimmin(3), uracil(4), $3-0-{\alpha}-D-glucopyranosyl-(1{\rightarrow}4)-{\beta}-D-glucopyranosyloxypeucedanin$ hydrates(5), respectively.

In this study, we conducted the anti-HIV-1 enzymes assay in vitro and its active components were predicted by QSAR in silico for the elucidation of action mechanism on anti-HIV of natural resources. The extracts of Gardenia jasminoides var. radicans Makino were tested for their inhibitory effects on the reverse transcriptase (RT), protease and ${\alpha}$-glucosidase. In the enzyme inhibition assay, the methanol extracts of Gardenia jasminoides var. radicans Makino stem showed a strong activity of 32.5% on the enzyme activity to cleave an oligopeptide, resembling one of the cleavage sites in the viral polyprotein which can only be processed by HIV-1 protease. Moreover the methanol extracts of stem exhibited alpha-glucosidase inhibitory activities of 26.1%. The methanol extracts ($100{\mu}g/ml$) of stem showed a weak activity of 13.4% on anti-HIV-1 RT using Enzyme Linked Oligonucleotide Sorbent Assay (ELOSA) method. However, all extracts of leaf and stem didn't exhibit the HIV-1-induced cytopathic effects with IC (inhibitory concentration) of $100{\mu}g/ml$ in HIV-1-infected human T-cell line. From these results, it is suggested that Gardenia jasminoides var. radicans Makino extracts may possibly be involved in the inhibition of reverse transcriptase, protease and alpha-glucosidase but can't vitally concerned with the viral replication in vitro.
