“…The occurrence of γ-Ln as a seed oil component was reported by previous workers in the plant families Boraginaceae, Onagraceae, Liliaceae, Aceraceae, Moraceae, Scrophulariaceae and Saxifragaceae (18), and by us in Ranunculaceae (19), Primulaceae (20) and in Saussurea, a genus of plant family Compositae (16). Seed oils of Oenothera biennis, Borago officinalis, and Ribes nigrum are currently the most common commercial sources of γ-Ln.…”

Seeds of Youngia tenuicaulis and other species from the plant family Compositae (Asteraceae) were studied for their oil content and fatty acid composition. The seed oil of Y. tenuicaulis growing in Mongolia was found to contain 5.6% gamma-linolenic acid (18:3delta6cis,9cis,12cis) in addition to common fatty acids. The oil was analyzed using chromatographic [capillary gas-liquid chromatography (GLC), thin-layer chromatography] and spectroscopic (infrared, gas chromatography-mass spectrometry) techniques. Seed oil fatty acids of Saussurea amara (containing gamma-linolenic acid) and of Arctium minus (containing 18:3delta3trans,9cis,12cis), as well as delta5cis- and delta5trans-18:3 were used as GLC reference substances. The evolution in this plant family of a large number of different 18:3 acids as well as the corresponding evolution of unusual desaturases should be investigated. On the other hand, the delta6cis-desaturase required for the biosynthesis of gamma-linolenic acid may have evolved independently several times in unrelated families of the plant kingdom.

“…It has been reported that seeds and the aerial part of plants from the family Primulaceae contain polyunsaturated fatty acids such as octadeca-6Z,9Z,12Z-trienoic (J-linolenic, 18:3 Z-6) and octadeca-6Z,9Z,12Z,15Z-tetraenoic (18:4 Z-3, stearidonic) [3][4][5].…”

“…The presence in seeds of J-linolenic acid in combination with a significant quantity of 18:4 Z-3 acid is a taxonomic signature of plants of the genus Primula [3]. The combination of these acids was observed in seed oils of plants from the families Boraginaceae [6], Saxifragaceae, and Scrophulariaceae [9], in addition to Primulaceae [3].…”

Polyunsaturated fatty acids of Cortusa turkestanica seed oil

et al. 2010

547.915 A. M. Nigmatullaev, and A. I. GlushenkovaThe composition of free and bound lipids from seeds of Cortusa turkestanica A. Lozinsk (Primulaceae) was studied. The fatty acid composition of principal acyl-containing classes was established using GC/MS. It was found that triacylglycerines isolated from free and bound lipids contained the usual acids and rarely encountered polyunsaturated 18:3 Z-6 (J-linolenic, 8.8 and 3.2%) and 18:4 Z-3 (stearidonic, 0.7 and 0.4%) acids and were enriched in linoleic acid (18:2, Z-6, 58.2 and 60.8%, respectively). It was found that polyunsaturated 18:3 Z-6 and 18:4 Z-3 acids were missing in the free form and were found among polar substances of bound lipids.The genus Cortusa (Primulaceae) includes at least ten plant species [1, 2], among which C. turkestanica A. Lozinsk is the only representative in the flora of Uzbekistan (endemic). It is distributed at middle mountain elevations in moist soils and along banks of streams.It has been reported that seeds and the aerial part of plants from the family Primulaceae contain polyunsaturated fatty acids such as octadeca-6Z,9Z,12Z-trienoic (J-linolenic, 18:3 Z-6) and octadeca-6Z,9Z,12Z,15Z-tetraenoic (18:4 Z-3, stearidonic) [3][4][5].J-Linolenic acid is typical of lipids from seeds of plants from the families Boraginaceae, Onagraceae, and Aceraceae [6-8]. The presence in seeds of J-linolenic acid in combination with a significant quantity of 18:4 Z-3 acid is a taxonomic signature of plants of the genus Primula [3]. The combination of these acids was observed in seed oils of plants from the families Boraginaceae [6], Saxifragaceae, and Scrophulariaceae [9], in addition to Primulaceae [3].It seemed interesting to establish the constituent composition of free (FL) and bound lipids (BL) and their fatty acids, especially because such data for plants containing polyene acids have not been reported except for seed oil of Oenothera biennis [6,10].Lipids were extracted from seeds stepwise. Seeds with 6.9% moisture were ground in a coffee grinder and extracted exhaustively with hydrocarbons (bp 60-70°C) to obtain free lipids in 11.03% yield (of the dry seed mass). The extract was yellow and contained carotinoids (24.0 mg%). FL were fractionated by column chromatography over silica gel. Lipid constituents of the resulting fractions were identified by TLC. The composition was determined after gravimetric estimation of the pure fractions (Table 1).The FL consisted of a rather simple set of constituents that was typical of lipids from seeds of higher plants. The main constituents were TAG. However, it should be noted that the content of esters of aliphatic and cyclic alcohols with fatty acids was somewhat elevated.BL were extracted from the remaining pulp by CHCl 3 :MeOH (2:1, v/v). The yield after purification was 2.72%. The extract was green and contained chlorophylls (52 mg%).The total yield of lipids was 13.75%; BL, 19.8%. TLC of the BL detected the main constituents TAG, glycolipids, and phospholipids. Free fatty acids (FFA), phytosterols, and mo...
