Lagotis brevituba Maxim is a perennial species distributed in the highlands of China, which has been used for more than 2000 years as a traditional Tibetan medicinal plant. However, no attention has been paid to the antioxidant activities of Lagotis brevituba Maxim in vitro or in vivo. Thus, this study aimed to evaluate the in vitro and in vivo ant...

As a clinically effective traditional Chinese medicine injection (TCMI), Shuanghuanglian injection (SHLI) is widely used in the treatment of upper respiratory tract infection and pneumonia. However, the shortage of quality analysis is a limitation that remains to be improved in the clinical application of SHLI. In this study, taking advantage of ul...

... We previously compared the antioxidant activities of L. brevituba in vivo and in vitro (5), and found that the water extract has strong 1,1-Diphenyl-2-picrylhydrazyl Free Radical (DPPH) free radical scavenging activity. We also found that L. brevituba had many polysaccharides. ...
This study purified two polysaccharides (LBMPs) from Lagotis brevituba Maxim in several steps. The chemical structure of LBMP-2 was determined by HPGPC, FT-IR, IC, ¹H and ¹³C NMR, AFM, SEM, and TEM. The results show that LBMP-2 was mainly composed of GalA, and the Mw of LBMP-2 is 23.799 kDa. In addition, the antioxidant activity, and the antitumor activity in vitro and in vivo were studied. LBMP-2 has excellent antioxidant and antitumor capacity. The inhibition of tumor cell proliferation in vitro may result in the inhibition of aerobic respiration and glycolysis. Tumor growth inhibition in vivo may inhibit the expression of AMPK in tumors and enhance spleen function. Compared with conventional chemotherapy drug cyclophosphamide, LBMP-2 is less harmful to the body and safer. Therefore, LBMP-2 provides a potential source of antitumor drugs.
An edible bird nest is a product of the solidified saliva secretion from a few different swiftlet’s species, during the breeding season. But the high impurities in A. maximus and C. esculent nests make them less ideal to be consumed. Eggshells and guano are the major contaminants contributing to the nitrite and nitrates contents. However, recent studies have shown significant medicinal and cosmetic applications of edible bird nest like anti-viral, anti-inflammatory, enhancing bone strength, and anti-aging. Thus, the high demand for edible bird nest in the global market to explore its potential application has improved from swiftlet farming activities to the cleaning process. Recent studies have shown the use of immobilized enzymes like keratinase for the removal of contaminants. The current review discusses the importance of Swiftlet bird nest, its application, and commercialization.
