Whitening Activity

Whitening cosmetics market has a bright future, and pure natural whitening products of traditional Chinese medicine have always been a research hotspot. In this research, the whitening active ingredient of Chinese medicine Trichosanthes pulp was isolated and purified for the first time, and its whitening mechanism was clarified. Chromatographic methods such as silica gel, ODS, and HPLC were used to isolate and purify them. B16 cells were used to measure the antioxidant activity, tyrosinase activity, and melanin removal activity. A total of 20 compounds were isolated, including p-hydroxybenzaldehyde (1), salicylic acid (2), vanillic acid (3), isovanillic acid (4), protocatechuate (5), trans-cinnamic acid (6), 4-coumaric acid (7), trans-ferulic acid (8), drechslerol-B (9), cyclotucanol 3-palmitate (10), 5-acetoxymethyl-2-furaldehyde (11), 5-hydroxymethylfurfural (12), diosmetin (13), apigenin (14), chrysoeriol (15), luteolin (16), 4′-hydroxyscutellarin (17), quercetin (18), 3′,5-dihydroxy-7-(β-D-glucopyranosyloxy)-4′-methoxyflavone (19), and cofloxacin-7-O-β-D-glucoside (20). Among them, compounds 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20 have good antioxidant repairing effects; compounds 3, 4, 5, 6, and 7 have high black inhibition; compounds 1, 2, 3, 4, 5, 6, 7, 8, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20 have obvious tyrosine acidase inhibitory activity. The results laid foundation for the further development and utilization of Trichosanthes pulp resources and also provide a basis for the development of natural whitening cosmetics.

Antitumour Effects

Abstract Cordyceps sinensis, a species of the genus Ascomycetes, is recognised as the most famous tonic herb and natural remedy in traditional Chinese medicine for centuries. Various pharmacological actions of the chemical constituents of C. sinensis have been reported, including: antitumour effects, hepatoprotective and anti-inflammatory effects, and antioxidant, nephroprotective and anti-apoptotic properties. In this study we tested the antioxidant activity of extracts of the fungus C. sinensis grown on two subspecies of rice, Oryza sativa var. Indica and Oryza sativa var. Japonica. The extracts were prepared with methanol by two different extraction procedures (reflux and ultrasound). The antioxidant activity of the extracts was determined by the DPPH assay. Our investigations showed that the sample 1 (grown on Oryza sativa var. Japonica) exhibited higher antioxidant activity than the sample 2 (grown on Oryza sativa var. Indica). The higher antioxidant activity of the sample 1 was observed with both extraction procedures.

Euphorbia Kansui

Kansui, the root of Euphorbia kansui T.N. Liou ex T.P. Wang, is a well-known traditional Chinese medicine. This paper reviews advances in investigations of the botany, the phytochemistry, the analytical method, the pharmacology and the toxicology of kansui. Nearly 100 compounds have been isolated from kansui and identified, and diterpenes and triterpenes are considered to be the characteristic and bio-active constituents of kansui. They possess multiple pharmacological activities, including diuretic, purgation, and antitumor effects. However, they also have a degree of toxicity, and can cause skin, oral, and gastrointestinal irritation. In this paper, the toxicity-efficacy relationship, attenuation and incompatibility of kansui are further discussed. Several future investigations of kansui are also proposed, all of which would improve the identification of kansui and other toxic herbs, as well as further their utilization.

Alzheimer's disease (AD) has become a worldwide disease that is harmful to human health and brings a heavy economic burden to healthcare system. Xiao-Xu-Ming Decoction (XXMD) has been widely used to treat stroke and other neurological diseases for more than 1000 years in China. However, the synergistic mechanism of the constituents in XXMD for the potential treatment of AD is still unclear. Therefore, the present study aimed to predict the potential targets and uncover the material basis of XXMD for the potential treatment of AD. A network pharmacology-based method, which combined data collection, drug-likeness filtering and absorption, distribution, metabolism, excretion and toxicity (ADME/T) properties filtering, target prediction and network analysis, was used to decipher the effect and potential targets of XXMD for the treatment of AD. Then, the acetylcholinesterase (AChE) inhibitory assay was used to screen the potential active constituents in XXMD for the treatment of AD, and the molecular docking was furtherly used to identify the binding ability of active constituents with AD-related target of AChE. Finally, three in vitro cell models were applied to evaluate the neuroprotective effects of potential lead compounds in XXMD. Through the China Natural Products Database, Traditional Chinese Medicine Systems Pharmacology (TCMSP) Database, Traditional Chinese Medicine (TCM)-Database @Taiwan and literature, a total of 1481 compounds in XXMD were finally collected. After ADME/T properties filtering, 908 compounds were used for the further study. Based on the prediction data, the constituents in XXMD formula could interact with 41 AD-related targets. Among them, cyclooxygenase-2 (COX-2), estrogen receptor α (ERα) and AChE were the major targets. The constituents in XXMD were found to have the potential to treat AD through multiple AD-related targets. 62 constituents in it were found to interact with more than or equal to 10 AD-related targets. The prediction results were further validated by in vitro biology experiment, resulting in several potential anti-AD multitarget-directed ligands (MTDLs), including two AChE inhibitors with the IC50 values ranging from 4.83 to 10.22 μM. Moreover, fanchinoline was furtherly found to prevent SH-SY5Y cells from the cytotoxicities induced by sodium nitroprusside, sodium dithionate and potassium chloride. In conclusion, XXMD was found to have the potential to treat AD by targeting multiple AD-related targets and canonical pathways. Fangchinoline and dauricine might be the potential lead compounds in XXMD for the treatment of AD.
