On the occasion of the 30th anniversary of the journal “Science and Technology of Cereals, Oils and Foods”, this paper summarized the development and prospects in the field of oil chemistry and processing technology in Academy of National Food and Strategic Reserves Administration (Academy of NFSRA) over the past 30 years. This scientific research carried out by the Academy of NFSRA in the field of oil chemistry and processing technology over the past 30 years and its outstanding contributions to promoting the development of the industry were also reviewed. According to the development strategy under the new situation of China, the highlighted work in the field of oil chemistry and processing technology was summarized, and the new opportunities and challenges faced by the field of oil chemistry and processing technology research was further prospected.

The present study investigated the chemical constituents in the aerial part of Cannabis sativa. The chemical constituents were isolated and purified by silica gel column chromatography and HPLC and identified according to their spectral data and physicochemical properties. Thirteen compounds were isolated from the acetic ether extract of C. sativa and identified as 3',5',4″,2-tetrahydroxy-4'-methoxy-3-methyl-3″-butenyl p-disubstituted benzene ethane(1), 16R-hydroxyoctadeca-9Z,12Z,14E-trienoic acid methyl ester(2),(1'R,2'R)-2'-(2-hydroxypropan-2-yl)-5'-methyl-4-pentyl-1',2',3',4'-tetrahydro-(1,1'-biphenyl)-2,6-diol(3), β-sitosteryl-3-O-β-D-glucopyranosyl-6'-O-palmitate(4), 9S,12S,13S-trihydroxy-10-octadecenoate methyl ester(5), benzyloxy-1-O-β-D-glucopyranoside(6), phenylethyl-O-β-D-glucopyranoside(7), 3Z-enol glucoside(8), α-cannabispiranol-4'-O-β-D-glucopyranose(9), 9S,12S,13S-trihydroxyoctadeca-10E,15Z-dienoic acid(10), uracil(11), o-hydroxybenzoic acid(12), and 2'-O-methyladenosine(13). Compound 1 is a new compound, compound 3 is a new natural product, and compounds 2, 4-8, 10, and 13 were isolated from Cannabis plant for the first time.

Selecting a herbicide suitable for broomcorn millet is a key issue in high efficiency and safe production of broomcorn millet and ecological environment improvement. We compared the control effects of 22 different herbicides on weeds as wells as their effects on growth and development of glutinous millet (Yumi 2) in the field. The results showed that, 1) soil applied Goyou, Butachlor, atrazine, and Benzipram, and stem- and leaf-applied WP mixture of tribenuron-methyl·carfentrazone-ethyl·MCPA-Na, Sigma Broad, Tengjing, Taoshi·Youxian and Kuofei had little phytotoxi-city, with broomcorn millet seedlings growing normally, and the other herbicides had phytotoxicities on broomcorn millet. 2) All the herbicides controlled weeds in the field to some extent, with better performance of soil applied herbicides than the stem- and leaf-applied ones, and affected plant height, functional leaf SPAD and spike weight per plant of broomcorn millet. 3) Compared with manual weeding, all herbicides reduced yields of glutinous millet. Compared with no herbicides application, some herbicides had yield-increasing effects. Among the soil applied herbicides, Go-you, Butachlor, atrazine, and Benzipram performed better in weeding control, increasing the yield of broomcorn millet by more than 60% compared with no herbicide control. Among the stem- and leaf-applied herbicides, Sigma Broad and WP mixture of tribenuron-methyl·carfentrazone-ethyl·MCPA-Na performed better in weeding control, increasing the yield of glutinous millet by more than 50% compared with no herbicide control. Therefore, applying 38% atrazine or 44% Monosulfuron to soil before the emergence of broomcorn millet, or stem- and leaf-applied 3.6% mesosulfuron-methyl or 55% WP mixture of tribenuron-methyl·carfentrazone-ethyl·MCPA-Na after the emergence of broomcorn millet, performed better in weeding control and with limited effects on the growth and development of broomcorn millet.
