Bazı maki türlerindeki uçucu asitlerin miktarı

Hammaddeye olan talebin son yıllardaki artışı orman endüstrisini alternatif kaynakları araştırmaya yöneltmiştir. Bu nedenle çalışmada maki bitkileri olan Laurus nobilis, Tamarix parviflora, Vitex agnus castus, Styrax officinalis, Fontanesia philliraeoides, Myrtus communis, Paliurus spina-christi ve Pistacia terebinthus ele alınmış ve söz konusu türlerde uçucu asitlerin miktarları belirlenmiştir. Bitkilere ait örneklerde formil ve asetil miktarları sırasıyla 2.21-3.58 mmol/100 g ve 84.16-89.42 mmol/100 g aralığında tespit edilmiştir. Formil ve asetil gruplarının toplam değerleri materyallerde %3.69 ile 3.94 aralığında sıralanmıştır. Maki bitkilerinden elde edilen sonuçların yapraklı ağaç türleri ile karşılaştırılabilir düzeyde olduğu görülmüştür.

Volatile acid content of some maquis species

In recent years, the increased demands for raw materials in wood industry have led researchers to investigate alternative raw material sources. Therefore, this study examined the volatile acid contents, which are considered as an important parameter in the different fields of wood utilization, from maquis species which are Laurus nobilis, Tamarix parviflora, Vitex agnus-castus, Styrax officinalis, Fontanesia philliraeoides, Myrtus communis, Paliurus spina-christi and Pistacia terebinthus. The formyl and acetyl contents were determined between 2.21-3.58 mmol/100 g and 84.16-89.42 mmol/100 g for maquis species, respectively. Total volatile acid contents calculated from formyl and acetyl groups were ranged from 3.69 to 3.94%. Results of the study indicated that mentioned maquis species are comparable to hardwood species.
