Abstract: In this paper qualitative analyses of the phospholipid components of Hevea latex of two asexual progeny Hongxing No. 1 (wind-tolerant species) and the 93-110 (chill-tolerant species) were carried out by using one dimensional thin-layer chromatography. Eight phospholipid components were separated, and six of them were detected, the two among' them are phospholipid components never detected before. Besides, authors have conducted rapid quntitative analysis of the distribution of various phospholipid components in total lipid, rubber phase and lower layer of Hevea latex by thin- layer chromatographic scanning and the corrective method of absorbance proportional coefficint.
