Eugenol-Based Polyacetylenes: Examining Its Synthesis and Utility | Chapter 5 | Recent Developments in Chemistry and Biochemistry Research Vol. 8

Eugenol (4-allyl-2-methoxyphenol) is the main component (80% by weight) of clove oil found in Indonesia and is widely used as perfumes, antioxidants, medicines, foods, and flavoring. Eugenol is an ingredient of inexpensive nature, containing hydrophilic and allyl phenolic functional groups, and is expected to be a major component of chemical synthesis that has eco-friendly properties. Eugenol is an inexpensive natural ingredient, which contains a functional group of phenolic hydroxyl and allyl and is to be a major component of chemical synthesis which is environmentally friendly. In order to conduct the study, Eugenol 99 % was purchased from Indesso.com Indonesia, [Rh(nbd)₂Cl] was purchased from Wako Japan, [Rh+] was synthesized according to the literature. MoCl₅ was purchased from Wako Japan. NaOH was purchased from Wako Japan. K₂CO₃ was purchased from Wako Japan. All Polymers were purified by HPLC. Monomer synthesis and polymer synthesis were synthesized according to the literature. Poly (1) to Poly (3) showed widespread UV-Vis absorption at 300-450 nm and poly (4) showed cotton and UV-vis effects at 400 nm. Solvents and temperatures can tune the helical structure of poly (4). The future of semiconductor materials can serve as smart textiles, lab on a chip, portable compact screens, and skin cancer treatment. With cheap and easy-to-obtain basic materials in Indonesia, this polymer is increasing in price. In the future, the helical polymer will become a very useful material. This material has a good prospect of being developed in Indonesia. It was concluded that Eugenol-based polyethylene can be applied as an electronic plastic and in the pharmaceutical industry. The continuation of research in synthesizing new polymers from eugenol ingredients and developing new functions should be continued.

Chemical Characterization of Cinnamomum tamala Leaves by HPLC Analysis | Chapter 12 | Socio-Scientific Interaction in Diabetes and Cancer and Its Management

 Cinnamomum tamala (CT) is the member of Lauraceae family and its leaves are most popularly used as spice in Indian food. Along with spice, it is associated with many medicinal values such as antioxidant, antidiabetic, antifungal, immunomodulation etc. On the basis of GC-MS analysis, Eugenol was reported as active constituent who is present in excess in non polar fraction. Here, the study about the qualitative analysis of different phytochemicals in defferent fractions of CT leaves along with their TLC fingerprinting. Phytochemical analysis was carried out by chemical reaction based and quantitative estimation of eugenol was done by High Performance Liquid Chromatography (HPLC) using C-18 column. Result shown that the distribution of different phytochemicals were varies in different fraction and maximum amount of eugenol was found in non polar fraction (Hexane fraction) and then in total methanol fraction. It was found in traces in successive ethyl acetate and methanol fraction.

Phytochemical Analysis of the Flower Buds, Pedicels and Leaves of Syzygium aromaticum (L.) Merril and Perry | Chapter 10 | Technological Innovation in Pharmaceutical Research Vol. 5

 The goal of this work was to use Gas-Chromatography Mass Spectrometry to examine the principal chemical components of Syzygium aromaticum flower buds, pedicels, and leaves. Eugenol is the main ingredient in all pedicels (79.75 percent), buds (74.12 percent), and leaves (51.03 percent ). Acetyleugenol, Caryophyllene, Humulene, and Caryophyllene oxide are also significant components in addition to eugenol. Eugenol's therapeutic properties include antibacterial, antifungal, antiviral, anticancer, anti-diabetic, anesthetic, and antioxidant properties.
