BRUCINE SÖZCÜĞÜ İNGILIZCE DİLİNDE NE ANLAMA GELİR?
Brucine
Brucine, striknin ile yakından ilişkili acı bir alkaloid. Birkaç bitki türünde, en çok bilinen Güneydoğu Asya'da bulunan Strychnos nux-vomica ağacında bulunur. Brusin strieknin ile ilgili iken, zehirli değildir. Yine de, 2 mg saflıktaki brusini tüketen bir insan, striknin zehirlenmesine (LD50 (sıçanlar, oral) 1 mg / kg, LD50 (tavşan, oral) 4 mg / kg) benzeyen semptomlara neredeyse kesinlikle maruz kalacaktır. Yetişkinlerde olası ölümcül dozun 1 gram olduğu tahmin edilmektedir. Başka bir kaynak, insanlarda minimum öldürücü doz 30 mg verir. Konsantre sülfürik asitteki bir brusinin bir çözeltisi, kırmızı renk veren nitratlar ve nitrik asit için test etmek için kullanılabilir. Tıbbi amaçlar için, brucine öncelikli olarak yüksek tansiyonun düzenlenmesinde ve diğer nispeten iyi huylu kalp rahatsızlıklarında kullanılır. Ticari olarak Amerika Birleşik Devletleri ve Avrupa Birliği'nin bazı bölgelerinde ekilmektedir. Alkaloid brucine, strychnine'e izostural olarak, ancak hidrojen atomlarından ziyade aromatik halka üzerindeki 9 ve 10 pozisyonlarında metoksi gruplarıyla bulunur. Hem akciğer hem de striykin, kiral çözünürlük, rasemik karışımların ayrılması için maddeler olarak yaygın olarak kullanılır.
