Double hexagonal chains” can be considered as benzenoids constructed by successive fusions of successive naphthalenes along a zig-zag sequence of triples of edges as appear on opposite sides of each naphthalene unit. In this paper, we discuss the numbers of k-matchings and k-independent sets of double hexagonal chains, as well as Hosoya indices and Merrifield–Simmons indices, and obtain some ex...

Two new ubiquinones, named antrocinnamone and 4-acetylantrocamol LT3, were isolated along with six known ubiquinones from Antrodia cinnamomea (Polyporaceae) mycelium. The developed HPLC analysis methods successfully identified eight different ubiquinones, two benzenoids, and one maleic acid derivative from A. cinnamomea. The ubiquinones 1-8 exhibited potential and selective cytotoxic activity a...

We present a new algorithm to canonize molecular graphs using the signature molecular descriptor introduced in the previous papers of this series. While developed specifically for molecular structures, the algorithm can be used for any graph and is not limited to acyclic graphs, planar graphs, bounded valence, or bounded genus graphs, for which polynomial time algorithms exist. The algorithm is...

Antrodia cinnamomea (AC) has been widely used as a folk medicine in the prevention and treatment of liver diseases, such as hepatitis, hepatic fibrosis, and hepatocellular carcinoma. Previous studies have indicated that triterpenoids and benzenoids show selective cytotoxicity against human hepatoma cell lines. The aim of the study was to compare the triterpenoid content of extract and the extra...

Benzene and pyrene can be synthetically linked to [o-COSAN]− keeping their aromaticity. In contrast, naphthalene anthracene are extruded in the same reaction. We have proven that extrusion is only favorable if number of Clar's π-sextets remains constant. Thus, Clar has answer whether an attached polycyclic aromatic hydrocarbon or not.

In recent years, foliar application of elicitors to the vineyard has been increasingly used, in particular, elicitation with methyl jasmonate (MeJ). However, due high cost this compound, it is necessary find a form which amount be used considerably reduced. Therefore, aim work was study for first time influence nanoparticles doped MeJ (ACP-MeJ) and (MeJ), using dose 1 mM versus 10 mM, respectiv...

Although a strong floral scent is typical of hybrid lilies, Asiatic lilies (Lilium spp.) have only weak scent. Therefore, developing new cultivars with pleasant scents an important objective in lily breeding programs. Among the wild species contributing to establishment, L. cernuum has characteristic that nose can perceive. We crossed twice introduce traits into and emission F1 plants their pro...

Abstract Background Raisins contain a wide range of secondary metabolites, including volatile compounds that may contribute to the health benefits and preference consumers. To our knowledge, this is one first studies concerning analysis in raisin. The goal study was compare composition Gök Üzüm ( Vitis vinifera L.) raisins produced from grapes dried before application two pre-treatments solutio...
