Thermogravimetric analysis (TGA) was used to study the thermal weight loss behavior of Pinus armandii Franch bark. The results showed that the pyrolysis reaction of P. armandii Franch bark was mainly carried out after 220°C, and the thermal stability was better before 220°C. The pyrolysis behavior and products of P. armandii Franch bark were studied by pyrolysis-gas phase-mass spectrometry (Py-GC/MS). The identified compounds can be classified into esters, alcohols, carbohydrates, acid anhydrides, aldehydes, ketones, alkenes, and organic acids. [ABSTRACT FROM AUTHOR]

In this paper through the detection and analysis of the extract of Ulmus pumila L. wood, it is found that it contains a large number of effective active ingredients for use in medicine, food, cosmetics, industry, etc. And it lays a theoretical foundation for the future development and utilization of high value-added products of Ulmus pumila L. wood extracts.

Thermogravimetric and pyrolytic analyses were carried out to detect the various active ingredients and chemical substances in the leaves of Chinese white pine (Pinus armandii Franch), which were then analyzed and studied to understand their functions and the functions of their chemical components. The chemical substances contained therein mainly represent acrylamide, glycidol, pyruvic aldehyde, formic acid, cyclopentadiene, acetic acid, isovaleraldehyde, benzoic acid, and stearic acid. These chemical ingredients can be applied to new bioenergy, medicinal fields, and food ingredients such as spices. These chemical components also provide a new scientific basis and developmental direction for the utilization of Pinus armandii. [ABSTRACT FROM AUTHOR]

With the increasingly severe energy situation, environmental pollution is becoming more and more serious. In order to make full use of resources, reduce environmental pollution, improve the comprehensive utilization rate of wood, and study the utilization potential of Lobed Kudzuvine Root Bark in high-value bio-energy and other high value-added industries. In the Lobed Kudzuvine Root Bark biomass oil, and the residue after the proposed active ingredients can be used as part of the biomass liquid fuel for future use. And some alcohols, acids, ketones, aldehydes, etc. can also be used as an excellent solvent commonly used in industry, aliphatic aldehydes, acids, phenols and their derivatives are chemical raw materials. Most of all, it reveals the economic value of Lobed Kudzuvine Root Bark and provides a scientific basis for the comprehensive utilization of high quality resources of Lobed Kudzuvine Root Bark.
