To study the chemical constituent from the antithrombus activity extract of Radix Aerio Fici Microcarpae. The isolation and purification of the extract were conducted by means of silica gel column chromatography, polyamide column chromatography and recrytallization. The structures of these compounds were elucidated based on the physicochemical properties and spectroscopic analysis. 7 compounds were isolated from the extract. They were identified as isovanillic acid (1), 4-hydroxybenzoic acid(2),3,4-dihydroxybenzoic acid (3), friedelane (4), alpha-amyrin acetate (5), lanosterol (6) and beta-sitosterol (7) . Compound 3,4 and 7 are isolated from this plant for the first time. Source

Antioxidant may provide anti-arthritic effect that contributes to resolution of inflammation. Gallic acid (GA) and its derivatives were reported to be effective in treatment of arthritis. But GA-suppressed cell proliferation may compromise its effect on chondro-protection. In this study, we synthesized sulfonamido-based gallate-JEZTC and investigated its effect on rabbit articular chondrocytes through examination of the cell proliferation, morphology, viability, glycosaminoglycan (GAG) synthesis, and cartilage-specific gene expression. Results showed that JEZTC could effectively promote chondrocyte growth and enhance secretion and synthesis of cartilage extracellular matrix (ECM) by upregulating expression levels of aggrecan, collagen II, and Sox9 genes. Expression of collagen I which marked chondrocyte dedifferentiation was effectively downregulated by JEZTC. In addition, hypertrophy that may lead to chondrocyte ossification could not be detected in JEZTC groups. The results indicated JEZTC can well preserve the phenotype of chondrocytes. Range of 2.344 to 9.375 μg/ml is the recommended dose of JEZTC, which showed increased cell proliferation. Especially, JEZTC of 4.688 μg/ml showed the best performance. This study might provide a basis for development of a novel agent for the treatment of symptomatic chondral and osteochondral lesions. © 2014, The Society for In Vitro Biology. Source

Disporum sinovietnamicum R. C. Hu & Y. Feng Huang sp. nov. is described and from southwestern Guangxi, China. It is morphologically closest to D. jinfoshanense X. Z. Li, D. M. Zhang & D. Y. Hong, but differs by having stems that are 35-90 cm tall, narrowly lanceolate and thinly leathery leaves, and ovate and glabrous tepals. © 2016 Nordic Society Oikos. Source

Anoectochilus nandanensis, a new species from northern Guangxi, China, is described and illustrated. It is similar to A. emeiensis K. Y. Lang in habit, but distinguished by the size of the plant, leaves and lateral sepals, as well as the flanges of the mesochile. © 2015 Nordic Society Oikos. Source
