Abstract:
The essential oils from the leaves, flowers and roots of cultivated Alpinia speciosa K. Schum. were examined by capillary GC and GC-MS. Monoterpenoids composed 89.6% of the total identified constituents of the leaf oil, out of which 59.3% were oxygenated, represented mainly by terpinen-4-ol (28.4%) and 1,8-cineole (19.2%). The flower and leaf oils had a uniform qualitative, but different quantitative composition. However, the flowers oil was also dominated by oxygenated monoterpenoids (68.9%) viz., terpinen-4-ol (26.0%), 1,8-cineole (24.4%) and linalool (6.1%), along with the monoterpene hydro

Background: Essential oils are promising candidates for the development of next-generation biopesticides, offering a sustainable alternative to traditional synthetic pesticides. Methods: In this study, essential oils from various parts of Alpinia breviligulata were subjected to chemical composition analysis using GC/MS and evaluated for their larvicidal activities against Aedes aegypti and Aedes albopictus mosquitoes following WHO guidelines. Results: The leaf essential oil is primarily characterized by the main components α-pinene (19.4%), caryophyllene oxide (15.1%), and α-copaene (8.5%). Es

Abstract:
The ginger family (Zingiberaceae) is one of the most diverse and abundant families in the plant kingdom in terms of number of species. In terms of chemistry, this is a family of plants containing much essential oil with mainly monoterpene and sesquiterpene derivatives, which has been widely used in medicine, food, and flavor industries. In our series of studies on ginger family plants, the two new species including Wurfbainia schmidtii (K. Schum.) Škorničk. &amp; A.D. Poulsen and Zingiber atroporphyreus Škorničk. &amp; Q.B.

ABSTRACT: The aim of this study is to determine some fruit characteristics of 19 different lines hybridized by previous regular studies. These lines were examined in order to determine the differences among volatile components and reveal the differences in comparison with the parents. Plant height (cm), fruit weight (g), fruit width (mm), fruit length (mm), fruit flesh thickness (mm), pungency, immature fruit color and mature fruit color were determined of parents and F4 lines. As a result, a wide range of variations were determined between lines and parents in terms of all parameters apart fr

Abstract:
Innovative approaches are urgently required to treat divestating bacterial diseases in the face of rising bacterial resistance rates. The current investigative work focused on hydro-distilling Tasmanian blue gum (Eucalyptus globulus) to isolate the essential oil, which was then tested for bioactivity, antioxidant capacity, and antibacterial activity using in-vitro and in silico assays. The antioxidant activity was avualated against DPPH and FRAP.
