Fruit plants produce various volatile compounds that emit distinct aroma characteristics and contribute to their flavor qualities. However, some of these substances, especially hydroxyl-group molecules, are in non-volatile glycosylated forms. This study aimed determine free glycosidically bound three Okinawan pineapple cultivars (‘N67-10′, ‘Yugafu’, ‘Yonekura’). The components squashed juice we...
Ocimum selloi Benth, a native plant of Brazil, has medicinal uses as anti-diarrheic, antispasmodic and anti-inflammatory product. The yield of essential oils of the inflorescences, containing flowers and seeds, was 0.6%, and the yield of leaves, collected in two different seasons, was 0.25% (June 2000) and 0.20% (January 2001), respectively. The essential oils of the inflorescences and leaves p...
Biogenic terpenes play important roles in ecosystem functioning and atmospheric chemistry. Some of these compounds are semi-volatile and highly reactive, such as sesquiterpenes and oxygenated terpenes, and are thus difficult to quantify using traditional air sampling and analysis methods. We developed an alternative approach to quantify emissions from live branches using a flow through enclosur...
A foundational study assessed effects of biochemical pathway introduction into poplar to produce eugenol, chavicol, p-anol, isoeugenol and their sequestered storage products, from potentially available substrates, coniferyl and p-coumaryl alcohols. At the onset, it was unknown whether significant carbon flux to monolignols vs. other phenylpropanoid (acetate) pathway metabolites would be kinetic...
Basil (O. gratissimum L) is a aromatic and medicinal plant widely used in traditional medicine in Morocco. The aim of this work was to study the effect of three plant growth regulators gibberellic acid (GA), indole 3-acetic acid (IAA) and benzylaminopurine (BAP) on the content and composition of essential oils of this plant, especially on the main compound (methyl chavicol) and its isomer (the ...
رومارن یا اکلیل کوهی با نام علمی Rosmarinus officinalis L. یکی از گیاهان معطر کشت شده در ایران می‌باشد، نمونه گیاهی از مزرعه تحقیقاتی گیاهان دارویی وابسته به مرکز آموزش عالی جهاد کشاورزی استان سمنان جمع‌آوری گردید و در مقیاس آزمایشگاهی و نیمه صنعتی به روش تقطیر با آب اسانس‌گیری شد. بازده اسانس به ترتیب 31/0 درصد و 26/0 درصد تعیین گردید. نمونه‌ها جهت مقایسه ترکیبهای شیمیایی اسانس آن توسط دستگاهه...
