Capsella bursa-pastoris (L.) Medic, common shepherd's-purse (Cruciferae), is a medicinal plant that is included in the VIIIth and IXth editions of USSR pharmacopoeia and is an official remedy in other countries. It is used for uterine bleeding, malignant ulcers and cancer of the stomach, tumors, uterine cancer and fibroma, and for all types of kidney bleeding and diseases in homeopathy [1, 2]. Extracts of leaves and roots are known to contain neutral lipids (62.6 and 58.5%), glyco(20.8 and 17.8%), and phospholipids (16.6 and 23.7%, respectively) [3]. Seed oil contains fatty acids (FA) up to 50% linolenic and ~1% erucic acid [4]. β-Carotene and β-sitosterol were identified in the aerial part [5]. We studied lipids of the aerial part of the plant collected during flowering in Tashkent district (April 2000). The ground aerial part was extracted first with benzine, yield 0.9%, and then CHCl3, yield 1.7%. The benzine extract was fractionated by preparative TLC (PTLC) using benzine—diethylether (4:2) into seven fractions: 1) polar lipids, pheophytins "a" and "b", monoacylglycerols, 34.7%; 2) diacylglycerols, sterols, chlorophylls "a" and "b", 12.4%; 3) free FAs, triterpenols, 25.8%; 4) unidentified compounds, 4.1%; 5) triacylglycerols (TAG), 6.7%; 6) waxy esters, 12.8%; 7) hydrocarbons, 3.5%. The CHCl3 extract was also separated by PTLC using the system for neutral lipids in order to purify it of them and chlorophyll pigments. The fraction of polar lipids was 65% of the total CHCl3 extract. Then, separation of the polar lipids by TLC in acetone gave 73% glycoand 27% phospholipids.
