Carob pod is the fruit of the carob tree (Ceratonia siliqua L. Fabaceae). The fruit and its products, sold both in large stores and local markets, contribute strongly to the diet of people living in the Mediterranean areas of Europe and Turkey. This study reports the composition of carob pods sampled in West and South Anatolia. Sucrose (437.3 mg/g dry weight), glucose (395.8 mg/g dry weight) and fructose (42.3 mg/g dry weight) were the major sugars identified and quantified in the fruit. Total phenolics (13.51 mg gallic acid equivalents [GAE]/g dry weight), proanthocyanidin (0.36 mg GAE/g dry weight), gallotannins (0.41 catechin equivalents [CE]/g dry weight) and flavanols (3.21 mg CE/g dry weight protein) content of the fruit were also determined. Gallic acid (3.27 mg/g dry weight) was the most abundant phenolic acid present in all three phenolic fractions (free, ester and glycoside) isolated from pods. Aspartic acid (18.25 mg/g dry weight protein) was the predominant amino acid in the pod protein fraction. Eight minerals were quantified in the fruit. Among the analyzed major minerals, K (9.70 mg/g dry weight) was the most abundant element present, and the pods were richer in Ca than in P and Mg. Levels of trace minerals were comparable to other plant species. The data are discussed in terms of the nutritional value of the carob pod. PRACTICAL APPLICATION The use of carob fruit and its food products in Turkey has been increasing in recent years. However, knowledge about the composition of carob fruit pod produced in Turkey as well as in Mediterranean countries is lacking. The present work describes a composition scale and the advantages to food technologists and consumers who use the fruit and its fruit products in their diets. The results of the study can also aid in the assessment of adequate compositional information for further studies.

The chemical composition of the chloroform extracts of flowers, stems, and roots of Tripleurospermum callosum (Boiss. & Heldr) E. Hossain growing along the northeastern coast of Turkey was studied by gas chromatographymass spectrometry (GC-MS). The GC-MS analyses of the chloroform extracts from air-dried parts of T. callosum yielded the identification of 93 compounds. These compounds were separated into eight classes that were terpenes-terpenoids, hydrocarbons, alcohols, acids, oxygen-containing compounds, steroids, aromatics, and others. Major compounds were moretenol (11.71%) in flower oil: linoleic acid (16.18%), n-hexadecanoic acid (17.88%), and 1-tricosene (13.41%) in stem oil: and n-hexadecanoic acid (6.18%) in root oil. Similarity, of chloroform extracts in flowers, stems, and roots of T. callosum were in the ratio of 13.77%, 45.99%, and 30.16%, respectively.
