Morinda citrifolia（Rubiaceae）
俗名為Noni，中文名為海巴戟天。海巴戟
天果實可以抑制肺癌及肉瘤的生長，也發
現果實中的多醣類物質具有免疫節的功
能；以酒精與己烷萃取海巴戟天葉發現具
有抗肺結核菌成分。本研究主要是探討海
巴戟天粗萃物對Vibrio vulnificus抗菌作
用；Vibrio vulnificus是革蘭氏陰性菌喜歡
生長在高鹽環境，會導致敗血症及傷口感
染。本實驗是以熱水及酒精萃取海巴戟天
之葉，果實，青莖及褐莖中有效成分，並
且評估海巴戟天之各種萃取物對於Vibrio
vulnificus的抗菌能力。結果顯示海巴戟天
葉，果實及青莖的水粗萃物對Vibrio
vulnificus有抗菌能力，最小抑制濃度為10
mg/ml。但是酒精粗萃物只有果實的部分在
濃度10 mg/ml 具有抗Vibrio vulnificus活
性。 Morinda citrifolia is reported to have a
broad range of therapeutic effects, including
antibacterial, antiviral, antifungal, antitumor,
anti-inflammatory, and immune enhancing
effects. In this study, the hot water and
ethanol crude extracts were isolated from the
leaves, fruits, green stems and brown stems
of Morinda citrifolia, which were further
used to estimate the antibacterial activity
against Vibrio vulnificus. Our results showed
that the aqueous from the leaves, fruits
and green stems of Morinda citrifolia reveal
the growth inhibition against Vibrio
vulnificus. The minimum inhibitory
concentration of Morinda citrifolia aqueous
extracts were determined for clinical and
environmental isolates of Vibrio vulnificus
with 10 mg/ml. The ethanol extracts form
fruits exhibit inhibitory activity at 10 mg/ml
except from leaves and stems
