atractylenolide-ii and Disease-Models--Animal

Atractylodes macrocephala Koidz is a widely used as a traditional Chinese medicine. Atractylenolides (-I, -II, and -III) are a class of lactone compounds derived from Atractylodes macrocephala Koidz. Research into atractylenolides over the past two decades has shown that atractylenolides have anti-cancer, anti-inflammatory, anti-platelet, anti-osteoporosis, and antibacterial activity; protect the nervous system; and regulate blood glucose and lipids. Because of structural differences, both atractylenolide-I and atractylenolide-II have remarkable anti-cancer activities, and atractylenolide-I and atractylenolide-III have remarkable anti-inflammatory and neuroprotective activities. We therefore recommend further clinical research on the anti-cancer, anti-inflammatory and neuroprotective effects of atractylenolides, determine their therapeutic effects, alone or in combination. To investigate their ability to regulate blood glucose and lipid, as well as their anti-platelet, anti-osteoporosis, and antibacterial activities, both in vitro and in vivo studies are necessary. Atractylenolides are rapidly absorbed but slowly metabolized; thus, solubilization studies may not be necessary. However, due to the inhibitory effects of atractylenolides on metabolic enzymes, it is necessary to pay attention to the possible side effects of combining atractylenolides with other drugs, in clinical application. In short, atractylenolides have considerable medicinal value and warrant further study.

Xiaoyaosan (XYS), a well-known formula for relieving depression, was originated from the book of "Taiping Huimin Heji Jufang" in Song Dynasty (960-1127 AD), composed of Radix Bupleuri, Radix Angelicae Sinensis, Radix Paeoniae Alba, Rhizoma Atractylodis Macrocephalae, Poria, Herba Menthae, Rhizoma Zingiberis Recens and Radix Glycyrrhizae with dose proportion of 6:6:6:6:6:3:2:2. It is commonly used for the treatment of depression-related syndromes in China. In the formula, Radix Bupleuri usually serves as the principal drug, Radix Angelicae Sinensis and Radix Paeoniae Alba serve as the ministerial drugs, Rhizoma Atractylodis Macrocephalae, Poria, Herba Menthae and Rhizoma Zingiberis Recens serve as adjunctive drugs, Radix Glycyrrhizae serves as messenger drug, they coordinate with each other and enhance the effect of the formula. In our previous experiments, the antidepressant effect of XYS was revealed. However, the antidepressant part (or component) of this prescription was still obscure.. An experimental despair animal model: the mice tail suspension test (TST) was used to evaluate the antidepressant activity of XYS and its fractions. GC-MS method was developed to identify the volatile components and determine 4 major volatile components in active fraction.. In the TST test, the effect of a low polar fraction (XY-EA) was superior to other fractions of XYS. 13 volatile compounds in the XY-EA were identified on the basis of standards, isolation and structural determination in our laboratory, NIST 05 database and literature data. The content of 4 major volatile compounds in XY-EA which is 6.703%.. The petroleum ether fraction (XY-EA) appears to be the active fraction of XYS. 4 major components Z-ligustilide, palmitic acid, atractylenolide I, and atractylenolide II may be the antidepressant active compounds.
