Many plants collected at Japan, China, Korea, Imdonesia and South America were applied to antitumor and / or cytotoxic screening tests against Sarcoma 180 ascites in mice and / or V-79, KB, P388 cultured cells. On the course of these screening tests, alcoholic extracts of Forsythia viridissima (Oleaceae), Eurycoma longifolia(Simaroubaceae), Rubia cordifolia and R. akane(Rubiaceae), Cissampelos pareira and Abuta concolor (Menispermaceae), Nardostachys chinensis (Valerianacese), Mansoa alliaceae (Bignoniaceae), Casearia sylvestris (Flacourtiacear), Maytenus ilicifolia (Celastraceae), Hedychium coronarium (Zingiberaceae), Croton palanostigma(Euphorbiaceae), Cocculus trilobus(Menispermaceae), Ginkgo biloba(Ginkgoaceae), Alpinia galanga and Cucculus zanthorrhiza(Zingiberaceae), Evodia rutaecarpa(Rutaceae), and Periploca sepium(Asclepiadaceae) showed significant activity and their active principles were clarified. In this paper, a few antitumor substances in above plants are introduced.

Morinda citrifolia, also known as Great Morinda, Indian Mulberry, or Noni, is a plant belonging to the family Rubiaceae. A number of major chemical compounds have been identified in the leaves, roots, and fruits of the Noni plant. The fruit juice is in high demand in alternative medicine for different kinds for illnesses such as arthritis, diabetes, high blood pressure, muscle ached and pains, menstrual difficulties, headache, heart diseases, AIDS, gastric ulcer, sprains, mental depression, senility, poor digestion, arteriosclerosis, blood vessel problems, and drug addiction. Several studies have also demonstrated anti-inflammatory, antioxidant and apoptosis-inducing effects of Noni in various cancers. Based on a toxicological assessment, Noni juice was considered as safe. Though a large number of in vitro, and, to a certain extent, in vivo studies demonstrated a range of potentially beneficial effects, clinical data are essentially lacking. To what extent the findings from experimental pharmacological studies are of potential clinical relevance is not clear at present and this question needs to be explored in detail before an recommendations can be made.

Hyaluronidase is one of the mucopolysaccharide-splitting enzyme and is related to the permeability of the vascular system and inflammation. An anti-hyaluronidase assay guided fractionation of the methanolic extract of Uncariae Ramulus et Uncus has furnished a pentacyclic triterpene, ursolic acid (compound I). Compound I exhibited hyaluronidase inhibitory activity with $IC_{50}$ value of 0.15 mM, and disodium cromoglycate showed the inhibitory activity with $IC_{50}$ value of 1.78 mM as a positive control.

Geniposide, an iridoid glucoside, has been isolated from the butanol fraction of Gardenia jasminoides Ellis (Rubiaceae). The component was found to be transformed into the blue pigments by some aerobic bacteria, suggesting that geniposide is the precursor for the formation of pigments after converting into genipin, an aglycon of geniposide, by ${\beta}-glucosidase$. Some bacteria having a ${\beta}-glucosidase$ activity did not form the pigments, which may mean that the formation of pigments can only be occurred by the reaction of any enzyme or compound in the pigment-producing bacteria.

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 a continuing study of the fermented noni (Morinda citrifolia) juice exudates, five compounds, heptanyl $2-O-{\beta}-{\small{D}}-xylofuranosyl-(1{\rightarrow}6)-{\beta}-{\small{D}}-glucopyranoside$ (1), n-butyl ${\beta}-{\small{D}}-glucopyranoside$ (2), (1S)-(3-ethenyl-phenyl)-1,2-ethanediol (3), (2S)-2-hydroxybutanedioic acid (4), and daucosterol (5) were isolated from the buthanol partition of the extract. The structures of the isolates were identified by 1D and 2D NMR, and MS experiments, as well as by comparison of their data with the published values. Among the isolates, compounds 1 - 3 were isolated for the first time from the plant species. The isolated compounds were evaluated for their cancer chemopreventive potential based on their ability to inhibit nitric oxide (NO) production and tumor necrosis factor alpha ($TNF-{\alpha}$)-induced $NF-{\kappa}B$ activity, and quinonone reductase-1 (QR1)-inducing effect.

Adventitious multiple shoots were developed from leaf, petiole and internode explants of Geophila reniformis D. Don. on MS medium supplemented with various concentrations of $N^6$-benzylaminopurine (BAP) or Kinetin (KIN) alone or in combination with indole-3-acetic acid (IAA). Leaf showed maximum organogenetic potential, followed by petiole and internode. Murashige and Skoog (MS) medium supplemented with 22.22 $\mu{M}$ BAP and 4.57 $\mu{M}$ IAA induced maximum shoot buds from leaf explants. Internodal segments showed low potential of direct organogenesis. The regenerated shoots rooted the best in presence of 10.75 - 13.44 $\mu{M}$ $\alpha$-naphthalene acetic acid (NAA) along with 2.22 $\mu{M}$ BAP, and were successfully established in the field with a survival rate of 89.11%.

An iridoid glycoside, oldenlandoside III (5) was isolated from the n-butanol fraction of methanol extracts of the aerial parts of Oldenlandia diffusa Roxb. along with six others previously characterized iridoid glycosides; geniposidic acid (1), scandoside (2), feretoside (3), 10-O-ben-zoylscandoside methyl ester (4), asperulosidic acid (6) and deacetylasperulosidic acid (7). Compounds 1, 2, and 7 inhibited LDL-oxidation, and showed $63.3{\pm}2.0,\;62.2{\pm}1.6,\;and\;63.8{\pm}1.5\%$ inhibition, respectively, at a concentration of 20 ${\mu}g/mL$.

Chemical constituents of Uncaria hooks were studied. Four compounds were isolated from the ether soluble fraction by chromatographic purification process. They were ident ified as isocorynoxeine-N-oxide, anti-isorhynchophylline-N-oxide, physcion and ursolic acid by spectral evidences. Their contents analyzed by HPLC or GC method were physcion 0.04%, ursolic acid 0.26%, isocorynoxeine-N-oxide 0.04% and anti-isorhynchophylline-N-oxide 0.03% respectively. Isocorynoxeine-N-oxide was not reported in nature so far.
