Chemical constituents of Brassica rapa Chinensis L. and Brassica rapa var. Parachinensis (Baily) Hanelt
Brassica rapa chinensis L. and Brassica rapa var. parachinensis (Baily) Hanelt were studied for their chemical constituents. The dichloromethane extracts of the leaves of Brassica chinensis L. afforded β-sitosteryl-3β-glucopyranoside-6'-O-fatty acid esters (1), β-sitosterol (2), chlorophyll a (...

| Summary: | Brassica rapa chinensis L. and Brassica rapa var. parachinensis (Baily) Hanelt were studied for their chemical constituents. The dichloromethane extracts of the leaves of Brassica chinensis L. afforded β-sitosteryl-3β-glucopyranoside-6'-O-fatty acid esters (1), β-sitosterol (2), chlorophyll a (3) and phytyl fatty acid esters (4), while the leaves of Brassica rapa var. parachinensis (Baily) Hanelt yielded 4, monogalactosyl diacylglycerol (5) and lutein (6). The structures of 1-6 were identified by comparison of their NMR data with those reported in the literature. |
