Neutral lipids from seeds of Asteraceae plants

Lipids from seeds of three plants of the Asteraceae family, Cousinia franchetii, Arctium leiospermum, and Rhaponticum integrifolium, were studied. The principal constituents of lipids from the three plants were shown to be acylglycerides of ordinary fatty acids and oxygenated fatty acids using chemical and chromatographic analyses. The composition of the ordinary unoxidized and epoxy acids was determined by GC. We investigated lipids from seeds of the Asteraceae plants Cousinia franchetii C. Winkl, Arctium leiospermum Jur. et Serg., and Rhaponticum integrifolium C. Winkl. Plants of the Cousinia genus are annual and perennial herbs, some of which bear rubber while others are good food plants [1a]. The species studied by us, C. franchetii, is endemic to Samarkand and Surkhandarin oblasts [2a]. Many species of the genus Arctium are medicinal plants, the oil from fruits of which finds application for treatment. A. leiospermum is distributed through Central Asia and Western and Eastern Siberia [2b]. Rhaponticum integrifolium is endemic to Pamiro-Alai and Fergan ridge [1b, 2c].Total neutral lipids were isolated from previously ground seeds by hexane extraction. The lipid content in seeds of C. franchetii was 29.0%; A. leiospermum, 15.8%; R. integrifolium, 14.8%.Neutral lipids were separated by column chromatography (CC). Table 1 lists the results. It can be seen that the lipid compositions are characterized by acylglycerides (AG) of both ordinary and oxygenated fatty acids (FA). Polar AG I and II were also oxygenated AG because their hydrolysis products contained epoxy-and hydroxyacids.The presence of AG of oxygenated FA is typical of lipids from Asteraceae plants [3][4][5][6][7][8][9][10][11][12][13].Lipids of A. leiospermum differ from the other two studied species by a high content of oxygenated AG consisting of almost half of the lipid mass (Table 1). The lowest content of oxygenated AG was found in C. franchetii, 6.2%. The principal lipid class was TAG, 90.3%, making up 70.0% of the lipid mass in R. integrifolium. Besides TAG, lipids of all three species contained DAG and MAG, the total content of which was greatest in R. integrifolium (11.6%) and least in C. franchetii (0.9%).The lipophilic components consisted of hydrocarbons, sterols, triterpenols and their esters with high-molecular-weight FA (Table 1). According to TLC and comparison with authentic compounds, normal paraffins and olefins were identified in all species. Squalene was found in the hydrocarbons from C. franchetii and A. leiospermum.The composition of ordinary fatty acids from AG was established by GC (Tables 2-4). The principal unsaturated components of the total acids of all species were 18:1 and 18:2 acids. Linoleic acid dominated almost all lipid classes. The exception was 1(3),2-DAG from C. franchetii, where half of the acid mass was 18:1 acid whereas the 1,3-DAG were enriched in 18:2 acid. Therefore, oleic acid is typically distributed primarily in the sn-2-position; linoleic, in the sn-3-position. The saturated acids were dominated by 16:0 ...

“…Alcohols were separated into three bands by preparative TLC on silica gel using solvent system 2: aliphatic alcohols, triterpenols, and sterols. The composition of the components in each band was established by GC (SE-30) and comparison with model samples obtained from lipids of Cousinia severtzovii seeds [6].…”

Lipids from Flowers and Leaves of Artemisia annua and Their Biological Activity

Chemical, chromatographic, and spectral methods were used to show that the main components of the lipid extract of flowers and leaves are free and bound aliphatic and cyclic alcohols (sterols and triterpenols) and essential oil. It was shown that the lipid extract of Artemisia annua has a positive influence on skin metabolism and possesses anti-inflammatory activity.Key words: Artemisia annua, hydrocarbon extract, polar lipids, fatty acids, skin metabolism, anti-inflammatory activity.Artemisia annua L. (annual wormwood, Asteraceae) grows in Central Asia, Siberia, Europe, North Africa, and America [1]. The antimalarial preparation artemisinin is isolated from its aerial part [2]. Furthermore, annual wormwood is a source of essential oil, the content of which is highest during flowering, ~0.7% of the dry mass [3].The plant lipids are practically unstudied. Only the isolation and identification of four lipophilic components have been reported [4]. Data on the pharmacological properties of these lipids are also lacking.Neutral lipids were isolated from the air-dried flowers and leaves by hydrocarbon (bp 75-80°C) extraction. Then, polar lipids were extracted from the remaining pulp by CHCl 3 :CH 3 OH (2:1 by vol). The CHCl 3 :CH 3 OH extract was purified of nonlipid components by washing with aqueous CaCl 2 (0.05%). The yield of neutral lipids was 4.3% of the air-dried mass; of polar, 4.2%.The hydrocarbon extract was brown and thick and had a characteristic wormwood odor. The carotinoid content was 240 mg%. The acid number of the extract was 1.5 mg KOH.Essential oil was separated from the hydrocarbon extract by steam distillation. The yield was 13.0% of the extract mass and ~0.55% of the dry mass. We have previously reported the composition of the essential oil [5].The total substances remaining after removal of essential oil were extracted from the aqueous layer by diethylether. The ether was removed. The extracted substances were separated by column chromatography over silica gel into individual fractions, extracting them with hexane with a gradually increasing concentration of diethylether from 0 to 100%. Substances were identified by TLC on silica gel using solvent systems 1 and 2 and comparison with model samples of lipids and lipophilic components, qualitative reactions, GC, and mass spectrometry. The contents of the substances were determined gravimetrically (Table 1).It can be seen that paraffins and olefinic hydrocarbons dominate the extract. According to mass spectrometry, they include saturated components of the C 32 -C 20 series (m/z 450-282 [M] + ), monoenes C 38 -C 20 (m/z 532-280 [M] + ), dienes and trienes C 38 -C 28 (m/z 530-390, 528-388 [M] + ), tetraenes C 38 -C 27 (m/z 526-372 [M] + ), and pentaenes C 38 -C 30 (m/z 524-412 [M] + ).The fraction of esters of aliphatic and cyclic alcohols consisted according to mass spectrometry of a combination of saturated fatty acids of the series 24:0-10:0 and unsaturated 18:1, 18:2, and 18:3 with aliphatic alcohols of the series C 30 -C 16 , stigmasterol, β-sitos...
