The effect of Rhinacanthus nasutus leaf extract on the growth of dermatophytes had been investigated. In vitro the extract exhibited high activity against various species of dermatophytes (Trichophyton mentagrophytes var. mentagrophytes, T. mentagrophytes var. interdigitale, T. rubrum, Microsporum canis and M. gypseum). The minimal inhibitory concentration (MIC) values of the extract revealed that all the dermatophytes tested had MIC values of 13.6 mg/ml. The extract exhibited fungistatic activity at lower concentrations $({\leq}13.6\;mg/ml\;or\;below\;the\;MIC\;value)$ and fungicidal activity at higher concentrations $({\geq}13.6\;mg/ml$\;or\;above\;the\;MIC\;value)$. The results suggested that the extract acted on the cell wall of the dermatophytes which subsequently leading to the formation of cytopathological and membrane structural degeneration and finally leading to cell lysis and death.

Sequiterpene lactone (1) has determined by spectroscopic analysis. This compound (1) inhibited the growth of the dermatophytic fungus Trichophyton mentagrophytes (ATCC 28185, 2 mm zone at $15{\mu}g/disk$), cytotoxic to murine leukaemia cell lines ATCC CCL 46 P388Dl, ($IC_{50}$ 1,125 ng/mL at $7.5{\mu}g/disk$) and BSC monkey kidney cell lines (100% of well at $15{\mu}g/disk$).

Disk assays on the compounds (10 and 12) showed both to have antifungal activity against the dermatophytic fungus Trichophyton mentagrophytes ATCC 28185, (1 and 3 mm inhibition zones at $60\;{\mu}g/disc$), but not against the Gram-positive bacterium B. subtilis or the Gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa or fungi Cladosporium resinae and Candida albicans. However, the compound (13) did not show against antifungal activity. The geranyloxy compounds (10, 12, and 13) were cytotoxic to P388 murine leukaemia cells ATCC CCL 46 P388D1, ($IC_50$ >6,250 ng/mL at $7.5\;{\mu}g/disc$). These results suggest that The geranyloxy compounds possesses antimicrobial and antitumor activities.

This study was carried out to investigate the anti-fungal effect of Pyrethri Flos Boiled Solution (PFBS) from Chrysanthemum Cinerariaefolium Visiani on Microsporum canis, Microsporum gypseum and Trichophyton Mentagrophytes with 0.5 ml, 1ml, 2 ml. In comparative drugs, on Sabouraud's glucose agar medium to 2 ml respectively and PFBS on the rabbit skin lesions, in vivo experiments, were observed. The results obtained were as follows : PFBS slightly suppresed the growth of the fungi in 0.5 ml and markedly it in 1 ml and 2 ml. In comparative drugs, benzylbenzoate represented similar anti-fungal action in 2 ml compared with PFBS. While, salicylic acid and boric acid represented less suppression of growth of the fungi than PFBS in 0.5 ml. The effects of PFBS on the rabbit skin lesions inoculation with dermatophytes was almost normally recorved about Microsporum gypseum, Trichophyton mentagrophytes except Microsporum canis after 8 days.

Bioactivity-directed isolation has led to the isolation of (-)-ent-costunolide (1) as the major active compound from Hepatostolonophora paucistipula. This compound (1) was determined by spectroscopic data interpretation. This sesquiterpene lactone (1) inhibited the growth of the dermatophytic fungus Trichophyton mentagrophytes ATCC 28185, (4 mm inhibition zone at $15{\mu}g$/disc), cytotoxic activity to murine leukaemia cell lines ATCC CCL 46 P 388D1 ($IC_{50}$ 687 ng/ml, at $0.075{\mu}g$/disk), BSC monkey kidney cell lines (100% of well at $15{\mu}g$/disk) and antiviral activity to Herpes simplex virus (0.25 mg/ml, 100% of well at $7.5{\mu}g$/disk) and Polio virus (0.125 mg/ml, 100% of well at $3.75{\mu}g$/disk). These results suggest that (-)-ent-costunolide (1) has potential antimicrobial and cytotoxic agents.

The effects of crude extracts from medicinal plants on biological activity were investigated. The crude ethanol extract of H. paucistipula inhibited the growth of the Gram positive bacterium Bacillus subtilis ATCC 19659, (2 mm inhibition zone at 150 ${\mu}g$/disc) and the dermatophyte Trichophyton mentagrophytes ATCC 28185, (7 mm inhibition zone at 150 ${\mu}g$/disc), and toxic to P388 murine leukaemia cells ($IC_{50}\;2.48\;{\mu}g/ml$ at 75 ${\mu}g$/disk).

The antifungal activities of the essential oils from Citrus borgamia. Ciderus atlantica. Cymbopogon ditratus, Eucalyptus globulus. Juniperus communis. Lavandula angustifolia. Melaeuca aterinfolia. Pelargonium graveolens. Pogestemon patchouli. Rosmarinus officinalis. Styrax tonkinensis. and Thymus vulgaris, which are recommended for the treatment of microbial infections in aromatherapy and complementary medicines. were tested against Trichophyton spp. The activities were measured by broth dilution method and disk diffusion assay. As the results, most of the test oils inhibited growth of T. tonsurans. T.mentagrophytes. T. ferugineum. and T. rubrum. Eapecially, the essential oils from C. atlantica. C. ditratus. e. globulus, and P. graveolens showed the strongest activity among the tested herb oils showing MICs between < 0.09 and 0.39 mg/ml.
