Two compounds 1-oleo-2, 3-dilinoleioglyceride (1) and 1,2-dioleo-3- linolenioglyceride (2) have been isolated from the ethyl acetate extract of fruits of Lycium chinense. Their structures have been elucidated with the help of 600 MHz NMR using 1D spectral method viz., 1H and 13C, aided by FAB MS and IR spectroscopy. The compounds 1-2 are reported for the first time in the fruits of L. chinense. Source

The essential oil and petroleum ether extract from the fruits of Lycium chinense Mill. (Solanaceae), were analyzed by gas chromatography-mass spectrometry (GC-MS). Out of 42 peaks, 40 components, which constituted 99.81%, were identified in the oil. The oil was dominated by acid and esters which accounted for 66.61 and 8.43%, respectively. The major constituents were hexadecanoic acid methyl ester (4.92%), hexadecanoic acid ethyl ester (9.92%), ethyl linoleate (3.45%), tetradecanoic acid (3.72%) and hexadecanoic acid (62.89%). Forty components, which constitute 99.50%, were identified in the petroleum ether extract. The major components of petroleum ether extract were hexadecanoic acid (17.43%), hexadecanoic acid ethyl ester (9.51%), hexadecanoic acid methyl ester (3.72%), ethyl linoleate (10.26%), and phytol (3.58%). The petroleum ether extract components were identified for the first time. The identity of constituents of essential oil and petroleum ether extract was confirmed on the basis of retention time and mass and supplemented library. Extracts of different polarity from fruits of L. chinense were investigated for their antioxidant activity. Two different bioassays were used, namely scavenging of the diphenylpicrylhydrazyl (DPPH) radical method and the other reducing power of Fe3+ method. The total phenolic content was quantified of each extract as well. Butanol, ethyl acetate and methanolic extracts contributed to the strongest antioxidant activity. The fruit extracts of medicinal plant (L. chinense) has potential as a natural antioxidant and thus inhibit unwanted oxidation process. ©2011 Academic Journals. Source

In this study, we investigated the anti-obesity activity of Aceriphyllum rossii ethanol extract on rat fed a high fat diet. Male SD rats were divided into four groups. Group 1 was the control. Group 2 was fed a high-fat diet. Group 3 was the positive control, fed a high-fat diet supplemented with Garcinia Cambogia extracts. Group 4 was fed a high fat diet supplemented with ethanol extracts of Aceriphyllum rossii (EEAR). Precisely 166 mg/kg of powdered Garcinia Cambogia extracts was used for Group 3. Also, 250 mg/kg of EEAR was used for Group 4. The Body weight increased Group 2, but decreased Group 4. The serum total cholesterol in Group 2 increased by 15.26% when compared to Group 1, but only increased 5.29% in Group 3 and 4.29% in Group 4. The liver and mesenteric adipose tissue weights of Group 2 increased compared to Group 1, whereas they decreased in Group 3 and Group 4. As a result of measuring the concentration of triglycerides in extracted livers, Group 2 showed a significant increase compared to the Group 1, and Groups 3 and 4 showed significant decrease compared Group 2. These results suggest that Aceriphyllum rossii ethanol extracts may be useful as an anti-obesity agent. Source

Lycium chinense, a famous Chinese medicinal herb, has long history of use as a traditional remedy for many diseases. One compound as a-D-glucopyranosyl-(2 → 1′)-α-L-arabinopyranosyl-(2′ → 1″)-α-L-arabinopyranosyl-(2″ → 1′″)-″- L-arabinopyranoside (1) was isolated from the butanol fraction of methanol extract of fruits of L. chinense. The compound 1 was investigated for scavenging of the diphenylpicrylhydrazyl (DPPH•) radical scavenging activity, reducing power and the phosphomolybdenum activity and the results demonstrate that the compound (1) has potential as a natural antioxidant.
