Effects of growing region and maturity stages on oil yield and fatty acid composition of coriander (Coriandrum sativum L.) fruit

Changes on oil yield and fatty acid profiles were studied during maturation of coriander (Coriandrum sativum L.) fruits cultivated in Menzel Temime and Oued Beja, Tunisia. Oil and petroselinic acid biosynthesis proceeded at a steady rate up to 16 DAF in Oued Beja and in 33 DAF in Menzel Temime. The first results show that a rapid oil accumulation started at newly formed fruits and continued until their full maturity. During fruit maturation, fatty acid profiles varied significantly among the growing regions and stages of maturity. Petroselinic acid had the highest amount at the 16th and the 33th DAF, in Oued Beja and Menzel Temime, respectively. In Oued Beja, at full maturity, the main fatty acids were petroselinic acid (80.90 ± 9.45%), followed by oleic (14.79 ± 2.25%), palmitic (3.50 ± 0.65%) and stearic (0.49 ± 0.09%) acids. Fatty acid profile of fruits cultivated in Menzel Temime showed that in fully ripe fruit, petroselinic acid is the main compound (80.86 ± 7.23%) followed by oleic (14.83 ± 2.05%), palmitic (3.27 ± 3.12%) and stearic (0.31 ± 0.05%) acids. In both growing region, fruit development resulted mainly in an increase of petroselinic acid and a decrease of palmitic acid. Saturated and polyunsaturated fatty acids decreased significantly and monounsaturated fatty acids increased during maturation of fruit. Oil composition at the first four stages of maturity has a healthy and nutritionally value and the last stages were with important economic and industrial applications. Coriander fruit is potentially an important source of petroselinic which have numerous industrial applications.

阿魏和防风浸出液对白灵菇菌丝生长的影响

通过在培养白灵菇2个菌株的PDA培养基中加入不同浓度阿魏和防风浸出液处理进行试验,从菌丝体的生长速度和长势方面比较了不同浓度的阿魏和防风浸出液对白灵菇母种菌丝体生长发育的影响。结果表明,阿魏和防风浸出液在对白灵菇母种菌丝体生长发育的影响方面存在着浓度上的差异,各种不同浓度的处理在菌丝体的生长速度和长势等方面均优于对照,其中以20 g/L的阿魏和防风浸出液对K3菌丝作用效果最好,10 g/L的阿魏对“清丰”菌丝体有明显的促进作用,40 g/L的防风浸出液是促进“清丰”菌丝体生长发育的最佳浓度。     

Molecular markers in some medicinal plants of the Apiaceae family

The internal transcribed spacers ITS1 and ITS2 in the18S-5.8S-26S rDNA repeat units were amplified and cloned from Angelica gigas Nakai, Angelica acutiloba (Siebold & Zucc.) Kitagawa, A. dahurica Maxim, Angelica decursiva (Miq.) Franch. & Savat, Bupleurum falcatum L. and Peucedanum japonicum Thunb. Sequence analyses showed that ITS1 is approx. 215 bp, the 5.8S gene is 162 bp and the ITS2 approx. 221 bp in all six species. The sequences are deposited at the EMBL Nucleotide Database. By including these new sequences in the Apiaceae phylogenetic tree, a third branch consisting of P. japonicum, A. gigas, P. decursivum and A. decursiva is added to theAngelica clade. Peucedanum does not forma distinct branch. The sequence obtained from Angelica dahurica collected in S. Korea is identical to that reported for the same species originating from China. A Bupleurum clade of three species was added to the tree showing closer relationship to theDaucus Laserpitium clade than the Angelica clade. RAPD analysis of all six species showed that the 10-base primer OPC-17 only, out of the20 Kit-C primers from Operon gave polymorphic banding patterns. This revised version was published online in July 2006 with corrections to the Cover Date.     

Regional and maturational effects on essential oils yields and composition of coriander (Coriandrum sativum L.) fruits

The composition of volatile components of the essential oils extracted from fruits of coriander (Coriandrum sativum L.) growing in two different Tunisian regions in both Menzel Temime and Borj El Ifaa was studied by GC and GC–MS. The highest oil yields were observed at final stages of maturity: 0.324 ± 0.09% and 0.327 ± 0.08%, in Menzel Temime and Borj El Ifaa, respectively. Essential oil yields were highly (P < 0.001) affected by the growing region, stages of maturity and their interaction. Essential oil composition changed significantly (P < 0.05) among the different stages of maturity and growing region. Linalool and geranyl acetate were the main compounds at full fruit maturity in the two studied regions. Growing region, stages of maturity and their interaction had a strong effect (P < 0.001) on 35 compounds. α-Pinene, sabinene, limonene, γ-terpinene, cis-dihydrocarvone and geranial were insensible to the regional factor.
