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). This crude ethanol extract of H. paucistipula is the strongest antimicrobial and cytotoxic activities against P388 murine leukaemia cells (ATCC CCL 46 P388D1).

Cytotoxic and antifungal activities were strongly shown by Fr. 4 (218 mg, P388 IC/sub 50/ 652 ng/ml at 75 μg/disc, IC50 834 ng/ml at 30 μg/disc and HM 8). The subfraction 4 - 3 that showed the most activity was cytotoxic to murine leukaemia cells ATCC CCl 46 P388D1, (44.0 mg, P388 IC50 302 ng/ml at 30 μg/disc).

The cytotoxic activity of 13(E)-labd-13-ene-8α, 15-diol (1) was evaluated against tumor cell lines. A comparison of IC/sub 50/ values of this compound in cancer cell lines showed that their susceptibility to this compound decreased in the following order: P388>B16{F10>MDA-MB-231>A549>KB>SNU-C4 by the MTT method. 13(E}-Labd-13-ene-8α, 15-diol (1) was the most effective growth inhibitor of P388 murine leukaemia cell lines, producing approximately 8.3㎍/mL of IC/sub 50/ in the MTT method.

뉴질랜드의 자생식물인 Brachyglottis monroi와 Trichocolea hatcheri의 에탄올추출물에 대한 생리활성을 조사한 결과, 그람음성균인 Bacillus subtilis (ATCC 19659, 1 mm inhibition zone at $150{\mu}g/disc$)와 피부곰팡이균인 Trichophyton mentagrophytes (ATCC 28185, 6 mm inhibition zone at $150{\mu}g/disc$)에 대한 억제효과가 관찰되었으며, 이들 추출물은 P388 murine leukaemia cells ($IC_{50}$ $23.96{\mu}g/mL$)에서도 세포독성이 나타났다. B. monroi의 에탄올추출물의 항바이러스효과는 T. hatcheri의 에탄올추출물보다 강한 활성이 관찰되었으며, T. hatcheri의 에탄올추출물의 항균효과는 B. monroi의 에탄올추출물보다 강한 활성을 나타났다. 그렇지만 P388 murine leukaemia cells ($IC_{50}>12,500{\mu}g/mL$)에 대한 세포독성은 아주 미미한 것으로 나타났다.

The effects of bioactive fractions from Brachyglottis monroi on biological activity were investigated. this bioactive subfraction 6-5 is the most cytotoxic to P388 murine leukaemia cell lines. A comparison of IC/sub 50/ values of these subfraction in cancer cell lines showed that their susceptibility to these subfractions decreased in the following order; Fr. 6-5 > Fr. 6-3 > Fr. 6-6 > Fr. 6-1 > Fr. 6-2 > Fr. 6-4 by the MTT method. Silica gel flash column chromatography concentrated the cytotoxic activity in subfraction 6-5 which eluted with 30% and 40% ethyl acetate : hexane gave a major bioactive (51 mg, P388 IC/sub 50/ 8,286 ng/mL at 7.5 ㎍/disc).

The effects of chloroform extract from Lepidolaena tayiorii (L. tayiorii) on antifungal activity were investigated. The crude chloroform extract of L. tayiorii inhibited the growth of the Gram positive bacteria Bacillus subtilis ATCC 19659, (5 mm inhibition zone at $150{\mu}g/disc$) and the dermatophytic fungus Trichophyton mentagrophytes ATCC 28185, (6 mm inhibition zone at $150{\mu}g/disc$), and cytotoxic to P388 murine leukaemia cells ATCC CCL 46 P388D1, ($IC_{50}\;405.0{\mu}g/mL\;at\;150{\mu}g$/disc) and cytotoxic to BSC monkey kidney cells (@ 5 mg/mL, $150{\mu}g/disc;$ +++: 100% activity). We suppose that this crude chloroform extract of L. tayiorii is the strong antimicrobial and cytotoxic activities.

The crude ethanol extract of B. repanda showed the cytotoxic activity against Polio virus (25% activity at $150{\mu}g$/disk) and the minor cytotoxic activity against BSC cells (African green monkey kidney). However, the crude ethanol extract of B. repanda was non-toxic to murine leukaemia cells CCL 46 P388D1 ($IC_{50}$, > 62,500 ng/ml). Cytotoxic and antifungal activities were strongly shown by Fr. 64-3 which was eluted with 90% $CH_3CN/H_2O$, 100% $CH_3CN$, and 50% $CH_3CN/H_2O$(SM 2 at $150{\mu}g$/disk). The fraction 64-3 also showed the most cytotoxic activity against murine leukaemia cells (128 mg, $IC_{50}$ 10,051 ng/ml at $75{\mu}g$/disk). These results suggest that this fraction has a potent antifungal activity against the dermatophytic fungus Trichophyton mentagrophytes ATCC 28185.
