Main Components

The extractives of C. camphora old bark were used to cure some special diseases; however, the biomedical constituents of extractives of C. camphora old bark are still not completely explained. Therefore, 350 °C-based pyrolysis- GC/MS technology was used to identify the top value-added biomedical constituents of old bark-based benzene/ethanol extractives from C. camphora trunk. 74 chemical constituents representing 99.17% were identified from 86 peaks. The main components are as: Dodecanoic acid, 1-(hydroxymethyl)-1,2-ethanediyl ester (15.717%), Octacosanoic acid, methyl ester (10.357%), Abietic acid (8.483%), Heptacosane (5.678%), Ethyl alcohol (5.282%), Hexadecanoic acid, 2-hydroxy-, methyl ester (3.365%), Hexacosanoic acid, methyl ester (2.936%), 1,2-Benzenedicarboxylic acid, butyl 2-methylpropyl ester (2.928%), 2-Methoxy-4-vinylphenol (2.692%), Hexadecanoic acid, ethyl ester (2.312%), Hexacosane (2.076%), Tetracosanoic acid, methyl ester (2.013%), etc. The analytical result showed that the 350 °C pyrolyzate of benzene/ethanol extractives from C. camphora old bark is abundant in biomedical constituents, and also contains other bioactive components, which can be used as top value-added materials of high-grade cosmetic, food, spice and chemical solvents.

The leaves of star fruit plants (Averrhoa carambola) have been traditionally used to cure many diseases, such as hypertension and fever. Besides, the leaves of this plant have also widely been used as the main raw material in lawar (a Balinese traditional food) making. In this research, the methanol extract of this plant leaves was analyzed and identified for active compound contents. The main objective of this research was to investigate types of possible active and applicable compounds contained in such leaves, previously extracted/macerated in methanol solution. Analysis was conducted by applying GC-MS instrumentation using methanol solution. The results showed that 10 possible active and applicable compounds (Butane, 1,1-diethoxy-3 methyl-(CAS)1.1-DII, Dodecanoic acid, methyk ester(CAS) methyl, Dodecanoic acid, methyl ester (CAS) Ethyl Laun, Pentadecanoic acid ethyl ester, Hexadecanoic acid methyl ester (CAS) Methyl pa, OCTADECA 9.12 DIENOIC ACID METHYL, 9-Octadecenoic acid methyl ester (E)-(CAS), Octadecanoic acid methyl ester, and (E) 9-Octadecanoic acid ethyl ester) were identified in methanol extract of such leaves. Among those compounds, Butane, 1,1-diethoxy-3-methyl and Hexadecanoic acid, methyl ester was two most abundance constituents with percentage of peak areas of 35.67% and 26.93%, respectively.

Danshen ( Salvia miltiorrhiza Bunge) is one of the most used medicinal plants in the Oriental medicine and has been well studied for application in modern medicine. In our continuing study on chemical constituents of danshen cultivated in Vietnam, using chromatography separation resulted in the isolation of six phenolic compounds including a benzophenone, iriflophenone 2- O- α-L-rhamnopyranoside (1), and five phenolic acids including rosmarinic acid (2), rosmarinic acid methyl ester (3), rosmarinic acid ethyl ester (4), salvianolic acid A methyl ester (5) and salvianolic acid A ethyl ester (6) from the butanol portion of the danshen crude extract. Beside the typically main phenolic acid components, to our knowledge, iriflophenone 2- O- α-L-rhamnopyranoside (1) was first isolated from salvia sp. On biological testing, compound 1 showed strong antiproliferative activity on HL-60 leukemia cells with the IC50 of 8.9 μM; compounds 1 and 3–6 inhibited markedly nitric oxide production in lipopolysaccharide-treated RAW 264.7 cells.
