Abstract
Ilicis Rotundae Cortex (IRC) consists of the bark of Ilex rotunda Thunb, and its chemical constituents mainly include flavonoid glycosides, phenols, and triterpenoid saponins. In this study, a preliminary analysis was performed to identify and obtain the chemical components from IRC to better control the quality of the medicinal materials and provide a chemical basis for the study of the efficacy of the active components. Simple and efficient sample pretreatment and ultrasonic-assisted extraction methods were used to analyze the mass spectrum fragments and fracture modes in the anion mode by UPLC-Q-TOF-MS/MS. Using a two-step strategy, the neutral loss, diagnostic ions, and characteristic fragments were studied to screen diverse skeletons and substitutions, and the possible compounds were identified by comparison with databases. The representative compounds were compared with the standard, and the mass spectrogram was found to match perfectly. Thus, our findings reveal that this method is feasible and reliable and can be used to analyze the chemical components of IRC. We identified 105 compounds, including 22 triterpenoid saponins, 15 chlorogenic acids, 33 phenylpropanoids and phenylpropanosides, 3 iridoids, 1 flavonoid, 10 lignans, 12 glycosides, and 9 other compounds. This method lays the foundation for further elucidating the pharmacodynamics of IRC and provides a practical method for the identification of IRC.

Curr Top Med Chem 2020; 20:698-709. [PMID: 31976836 DOI: 10.2174/1568026620666200124105027] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2019] [Revised: 10/10/2019] [Accepted: 10/25/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND Medicinal phytochemistry involving UPLC-DAD in an exhaustive analysis involving quantification of eight commercially important phytochemicals viz. syringin, cordifolioside A, magnoflorine, tinocordiside, palmatine, 20β-hydroxyecdysone, L-tetrahydropalmatine and berberine has been done in 143 accessions from eight states and the union territories of Delhi and Jammu & Kashmir of India representing three different ploidy levels viz. diploid (2x), triploid (3x) and synthetic tetraploid (4x). The study was done to assess the effect of sex, ploidy level and ecogeography on the expression level of secondary metabolites in stems of dioecious, medicinally important shrub Tinospora cordifolia. METHODS Two different UPLC-DAD methods were used for the quantification of eight selected phytochemicals from the alcoholic stem extracts of T. cordifolia accessions. The Waters Acquity UPLC system hyphenated to the QTOF micromass system, equipped with PDA and ESI-Q-TOF detectors was utilized for the quantitative analysis, Mass Lynx v 4.0 software was used for data analysis. RESULTS Significant quantitative changes were observed in the analysed secondary metabolites among different accessions of T. cordifolia. The triploid (3x) cytotypes revealed higher amounts of seven out of eight analysed secondary metabolites than diploids and only 20β-hydroxyecdysone was observed to be present in significantly higher amount in diploid cytotypes. Further, at the tetraploid level, novel induced colchiploid (synthetic 4x) genotypes revealed increase in the yield of all of the analysed eight phytochemicals than their respective diploid counterparts. The quantity of active principles in tetraploid cytotypes were also higher than the average triploid levels at multiple locations in five out of eight tested phytochemicals, indicating the influence of ploidy on expression levels of secondary metabolites in T. cordifolia. Additionally, at each of the three ploidy levels (2x, 3x and synthetic 4x), a significant sex specificity could be observed in the expression levels of active principles, with female sex outperforming the male in the content of some phytochemicals, while others getting overexpressed in the male sex. The manifestation of diverse ecogeographies on secondary metabolism was observed in the form of identification of high yielding accessions from the states of Madhya Pradesh, Delhi and Himachal Pradesh and the Union territory of Jammu & Kashmir. Two triploid female accessions that contained approximately two- to eight fold higher amounts of five out of the eight analysed phytochemicals have been identified as superior elites from the wild from the states of Delhi and Madhya Pradesh. CONCLUSION The paper shows the first observations of ploidy specificity along with subtle sex and ecogeography influence on the expression levels of secondary metabolome in T. cordifolia.

Abstract
Ilex Rotunda Thunb has been shown to have anti-inflammatory and antioxidant effects. In human keratinocytes, we investigated the effect of rotundarpene (4-caffeoyl-3-methyl-but-2-ene-1,4-diol) on the TNF-α-stimulated production of inflammatory mediators in relation to the Akt, mTOR, and NF-κB pathways, and the JNK and p38-MAPK. Rotundarpene, Akt inhibitor, Bay 11-7085, rapamycin, and N-acetylcysteine inhibited the TNF-α-stimulated production of cytokines and chemokines, increase in the levels of p-Akt and mTOR, activation of NF-κB, and production of reactive oxygen species in keratinocytes. TNF-α treatment induced phosphorylation of the JNK and p38-MAPK. Inhibitors of the c-JNK (SP600125) and p38-MAPK (SB203580) reduced the TNF-α-induced production of inflammatory mediators, binding of NF-κB to DNA, and activation of the JNK and p38-MAPK in keratinocytes. The results show that rotundarpene may reduce the TNF-α-stimulated inflammatory mediator production by suppressing the reactive oxygen species-dependent activation of the Akt, mTOR, and NF-κB pathways, and activation of the JNK and p38-MAPK in human keratinocytes. Additionally, rotundarpene appears to attenuate the Akt, mTOR, and NF-κB pathways and the JNK and p38-MAPK-mediated inflammatory skin diseases.

Abstract
CONTEXT Lyoniside is the major constituent of Saraca asoca Linn. (Caesalpiniaceae) bark. There is an immediate need to develop an efficient method to isolate its chemical constituents, since it is a therapeutically important plant. OBJECTIVE A rapid extraction method for lyoniside based on microwave-assisted extraction of S. asoca bark was developed and optimized using response surface methodology (RSM). MATERIALS AND METHODS Lyoniside was analyzed and quantified by high-performance liquid chromatography coupled with ultraviolet detection (HPLC-UV). The extraction solvent ratio (%), material solvent ratio (g/ml) and extraction time (min) were optimized using Box-Behnken design (BBD) to obtain the highest extraction efficiency. The optimal conditions were the use of 1:30 material solvent ratio with 70:30 mixture of methanol:water for 10 min duration. RESULTS The optimized microwave-assisted extraction yielded 9.4 mg/g of lyoniside content in comparison to reflux extraction under identical conditions which yielded 4.2 mg/g of lyoniside content. Under optimum conditions, the experimental values agreed closely with the predicted values. The analysis of variance (ANOVA) indicated a high goodness-of-fit model and the success of the RSM method for optimizing lyoniside extraction from the bark of S. asoca. DISCUSSION All the three variables significantly affected the lyoniside content. Increased polarity of solvent medium enhances the lyoniside yield. CONCLUSION The present study shows the applicability of microwave-assisted extraction in extraction of lyoniside from S. asoca bark.

LC-MS/MS Determination and Pharmacokinetic Study of Pedunculoside in Rat Plasma after Oral Administration of Pedunculoside and Ilex rotunda Extract. Molecules 2015; 20:9084-98.

Abstract
Ilex rotunda is widely used to treat many disorders as a traditional Chinese medicine (TCM) containing 4%–5% pedunculoside (PDC). A rapid, selective, and sensitive liquid chromatography-tandem mass spectrometry method (LC-MS/MS) was developed and validated to determine PDC in rat plasma by using 3β,19α-dihydroxyurs-12-en-28-oic acid 28-β-D-glucopyranosyl ester (DEOG) as an internal standard. The analytes were extracted by protein precipitation and eluted on a C18 chromatography column using a mobile phase of methanol–H2O (70:30, v/v) delivered at a flow rate of 0.6 mL/min. Detection was performed using positive ion electrospray ionization in multiple reaction monitoring modes. The assay was linear over the concentration range of 0.60 ng/mL to 200 ng/mL, with a quantification limit of 0.60 ng/mL. Intra-day and inter-day precisions (%RSD) ranged from 2.12 to 9.51 for PDC, whereas the accuracy was within −7.83%~9.40%. The validated method was successfully applied to the pharmacokinetic study of PDC in rat plasma after oral administration of pure PDC and Ilex rotunda extract (IRE). Pharmacokinetic parameters of PDC in IRE, such as Cmax, AUC0–t, AUC0–∞, t1/2z, and CLz/F, statistically differed from those of the pure monomer (p < 0.01). However, Tmax and MRT showed no significant differences between the two groups. Results suggested that other coexisting components in IRE may decrease the absorption of PDC. Compound-compound interactions between PDC and other herbal extract components can alter the pharmacokinetic behavior of PDC. The study will be helpful in providing references for understanding the action mechanism and clinical application of Ilex rotunda.

Abstract
The extract of from the barks of Ilex Rotunda Thunb has demonstrated anti-inflammatory and anti-oxidant effects. Nevertheless, the effect of rotundarpene (4-caffeoyl-3-methyl-but-2-ene-1,4-diol) on the neuronal cell death induced by cholesterol oxidation products is unclear. We assessed the preventive effect of rotundarpene on the cholesterol oxidation product-induced apoptosis in neuronal cells using differentiated PC12 cells. 7-Ketocholesterol and 25-hydroxycholesterol induced a decrease in Bid, Bcl-2, Bcl-xL and survivin protein levels, increase in Bax levels, loss of the mitochondrial transmembrane potential, cytochrome c release, activation of caspases (-8, -9 and -3), cleavage of PARP-1 and an increase in the tumor suppressor p53 levels. Rotundarpene attenuated the cholesterol oxidation product-induced changes in the apoptosis-related protein levels, formation of reactive oxygen species, depletion of GSH, nuclear damage and cell death. The results show that rotundarpene may attenuate the cholesterol oxidation product-induced apoptosis in PC12 cells by suppressing the activation of the mitochondrial pathway and the caspase-8- and Bid-dependent pathways. The preventive effect appears to be attributed to its inhibitory effect on the formation of reactive oxygen species and depletion of GSH. Rotundarpene appears to attenuate cholesterol-oxidation product-mediated neuronal degeneration.

Abstract
The extract and hemiterpene glycosides of Ilex rotunda Thunb have demonstrated antioxidant and anti-inflammatory effects. Nevertheless, the effect of rotundarpene on the tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-induced apoptosis in keratinocytes that may be involved in skin diseases has not been studied. In this respect, we investigated the effect of rotundarpene on TRAIL-induced apoptosis in human keratinocytes. TRAIL triggers apoptosis by inducing a decrease in the cytosolic levels of Bid, Bcl-2, Bcl-xL, and survivin proteins, increase in the cytosolic levels of Bax, and increase in the mitochondrial levels of VDAC1, loss of the mitochondrial transmembrane potential, release of cytochrome c, activation of caspases (-8, -9, and -3), cleavage of PARP-1, and an increase in the tumor suppressor p53 levels. Treatment with rotundarpene prevented TRAIL-induced changes in the levels of apoptosis-related proteins, formations of reactive oxygen species and nitric oxide, nuclear damage, and cell death. These results suggest that rotundarpene may reduce TRAIL-induced apoptosis in human keratinocytes by suppressing the activation of the caspase-8- and Bid-pathways and the mitochondria-mediated cell death pathway, which is associated with the formation of reactive oxygen species and reactive nitrogen species. These data suggest that rotundarpene appears to be effective in the prevention of TRAIL-induced apoptosis-mediated skin diseases.

Abstract
Wax esters are long-chain esters that have been widely applied in premium lubricants, parting agents, antifoaming agents and cosmetics. In this study, the biocatalytic preparation of a specific wax ester, cetyl octanoate, is performed in n-hexane using two commercial immobilized lipases, i.e., Lipozyme® RMIM (Rhizomucor miehei) and Novozym® 435 (Candida antarctica). Response surface methodology (RSM) and 5-level-4-factor central composite rotatable design (CCRD) are employed to evaluate the effects of reaction time (1–5 h), reaction temperature (45–65 °C), substrate molar ratio (1–3:1), and enzyme amount (10%–50%) on the yield of cetyl octanoate. Using RSM to optimize the reaction, the maximum yields reached 94% and 98% using Lipozyme® RMIM and Novozym® 435, respectively. The optimum conditions for synthesis of cetyl octanoate by both lipases are established and compared. Novozym® 435 proves to be a more efficient biocatalyst than Lipozyme® RMIM.
