As the energizing and therapeutic effects of infusions of mate(Ilex paraguariensis ***.-Hil)leaves are increasingly recognized,rising global consumption is also increasing the demand for plantlets with high genetic and morphological ***-cuttings are an alternative for clonal plantlets;however,more details are needed on factors that affect the success of this ***,toward maximizing production,we evaluated adventitious rooting competence of mini-cuttings of different sizes and the morphophysiological quality of the resultant ***(one bud;length up to 2.5 cm),medium(multiple buds;length 2.6–5.0 cm),and large(multiple buds;length 5.1–10.0 cm)mini-cuttings were planted in a mixture of commercial substrate,vermiculite,and coarse sand(1:1:1 v:v:v),grown in a humidity chamber,then evaluated after 45,60,75,and 90 days for survival,percentage of callus and shoot formation,number and length of shoots,percentage of rooted cuttings,and number and length of *** rooted mini-cuttings were then cultivated in commercial substrate and subsurface soil(2:1 v:v)and evaluated after 30,60,90 and 120 days of cultivation for morphophysiology of the plantlets,percentage of survival,number of leaves,shoot height,stem diameter,and ratio of shoot height to stem *** 120 days,the plantlets were evaluated for the ratio of shoot and root dry mass,total length,surface area,total volume,and mean diameter of roots and Dickson quality *** rooting of the mini-cuttings and the morphophysiological quality of the plantlets were not influenced by the size of the vegetative ***,single-bud mini-cuttings have similar adventitious rooting competence,and result in plantlets with adequate morphophysiological quality,based upon leaf development,shoot height,stem diameter and length,and surface area,volume and diameter of ***-bud mini-cuttings up to 2.5 cm long can thus be used to maximize production of mate plantlets by mini-c

Ilex cornuta (***)is a traditional Chinese medicine (TCM)that has been used in clinical practice for hundreds of *** order to provide more information about the chemical basis of its pharmacological effects,phytochemical investigation on the roots of L cornuta was conducted in this *** roots of the plant were firstly extracted with 95% EtOH,and then the crude was partitioned with petroleum ether,EtOAc and n-butyl *** chromatographies were employed to isolate the crude step by step and the crude was further purified by semipreparative high performance liquid chromatography (HPLC).As a result,two new triterpenoid saponins (1,2),together with 12 known compounds (3-14),were isolated from the roots of I. *** structures were determined based on nuclear magnetic resonance (NMR),mass spectrum (MS)technologies,chemical reactions as well as gas chromatography (GC).Compounds 4,6,8,11,12 and 13 were isolated from this genus for the first *** structures of compounds 1 and 2 were determined as 3β-O-α-D-xylopyranosyl-(1→3)-α-L-2-O-acetylarabinopyranosyl-(1→2)-β-D glucopyranosyl-23-hydroxyl-20α(H)-urs-12-en-28-oic acid 28-O-β-D-glucopyranosyl ester (1)and 3β-O-α-D-xylopyranosly-(1→3)-α-L-2-O-acetylarabinopyranosyl-(1→2)-β-D-glucopyranosyl-19α,23-dihydroxyl-20α(H)-urs-12-en-28-oic acid 28-O-β-D-glucopyranosyl ester(2).

In the present study, three new triterpenoids, 23-hydroxyurs-12, 18-dien-28-oic acid 3β-O-α-L-arabinopyranoside(1), 23-hydroxyurs-12, 18-dien-28-oic acid 3β-O-β-D-glucuronopyranoside-6-O-methyl ester(2), and urs-12, 18-dien-28-oic acid 3β-O-β-D-glucuronopyranoside-6-O-methyl ester(3), and a known triterpenoid, 3β-hydroxy-urs-2, 18-dien-28-oic acid(4, randialic acid B), were isolated from the aerial parts of Ilex cornuta. Their structures were identified by the spectroscopic analyses(IR, ESI-MS, HR-ESI-MS, and 1D and 2D NMR) and chemical reactions. Compound 4 showed significant cell-protective effects against H_2O_2-induced H9c2 cardiomyocyte injury. Compounds 1-4 did not show any significant DPPH radical scavenging activity.

Chinese Herbal Medicines 2016年第3期8卷 209-230页

作者： Fan Yi Xiao-ling Zhao Yong Peng Pei-gen Xiao Institute of Medicinal Plant Development Chinese Academy of Medical Sciences Peking Union Medical College

The genus Ilex L. has been used as remedies in traditional Chinese medicine in aquifoliaceae and beverages for thousands of years due to abundant pharmaceutical bioactivities. There are 600 species in genus IlexL. containing various compounds such as terpenoids, saponins, glycosides, etc. Three species, L cornuta, I. chinensis, and L rotunda have been admitted in Chinese Pharmacopoeia 2015 to treat dyspepsia, stomatitis, and hyperactivity cough and protect the liver and kidney. Recent studies showed that several species have been daily drunk to promote human health and prevent cardiovascular diseases in the folk. Here we reviewed the genus Ilex L. in phytochemistry, ethnopharmacology, and pharmacology.
