Taxus Baccata - Porsuk Ağacı

Avrupa, Akdeniz ülkeleri ve Kafkasya'da yayılış gösteren porsuk ağacı ülkemizde ülkemizde kuzeyden güneye birçok yörede görülür. Kendi başına büyük ormanlar kurmaz. Kayın, göknar, ladin ormanlarında tek tek veya küçük gruplar halinde bulunur. Bazen küçük bir çalı, bazen sık dallı yuvarlak tepeli bir ağaç formunda görülür.

Esnek odunu, eski çağlarda yay yapımında kullanılmıştır. Yaprak ve genç sürgünlerinde "taksol" adlı zehirli bir alkoloid vardır. Bu alkaloid kanser tedavisinde kullanılır. Buna karşın tohumunun kırmızı renkli kapçığı zehirsizdir ve yenilebilir.


Taxus baccata is a conifer native to western, central and southern Europe, northwest Africa, northern Iran and southwest Asia.[1] Originally and still widely known in English as just Yew. It is a small to medium-sized evergreen tree, growing 10-20 m (exceptionally up to 28 m) tall, with a trunk up to 2 m (exceptionally 4 m) diameter. The bark is thin, scaly brown, coming off in small flakes aligned with the stem. The leaves are lanceolate, flat, dark green, 1-4 cm long and 2-3 mm broad, arranged spirally on the stem, but with the leaf bases twisted to align the leaves in two flat rows either side of the stem, except on erect leading shoots where the spiral arrangement is more obvious. The leaves are highly poisonous.
All parts of the tree are toxic, except the bright red aril surrounding the seed, enabling ingestion and dispersal by birds. The major toxin is the alkaloid taxine.
Yew is also associated with Wales and England because of the longbow, an early weapon of war developed in northern Europe, and as the English longbow the basis for a mediaeval tactical system. Yew is the wood of choice for longbow making; the bows are constructed so that the heartwood of yew is on the inside of the bow while the sapwood is on the outside. This takes advantage of the natural properties of yew wood since the heartwood is able to withstand compression while the sapwood is elastic and allows the bow to stretch. Both tend to return to their original straightness when the arrow is released. Much yew is knotty and twisted, so unsuitable for bowmaking; most trunks do not give good staves and even in a good trunk much wood has to be discarded.
The precursors of chemotherapy drug Paclitaxel can be derived from the leaves of European Yew, which is a more renewable source than the bark of the endangered Pacific Yew (Taxus brevifolia). This ended a point of conflict in the early 1990s; many environmentalists, including Al Gore, had opposed the harvesting of paclitaxel for cancer treatments. Docetaxel (another taxane) can then be obtained by semi-synthetic conversion from the precursors.
