Caffeoyl Quinic Acid

Gardenia latifolia Ait. (Rubiaceae) is also known as Indian Boxwood is a small deciduous tree often growing in southern states of India. In the present study, phytochemical profiling of methanolic extract of G. latifolia fruits were carried out using FTIR and LC-MS/MS analysis. Besides, its antioxidant and antimicrobial potential have been analysed using DPPH activity, differential pulse voltammetry and resazurin microtiter assay, respectively. Phytochemical profiling revealed the presence of 22 major diversified compounds and main were 3-caffeoyl quinic acid (chlorogenic acid), 3,4-Di-O-caffeoyl quinic acid, 6-O-trans-feruloylgenipin gentiobioside, 10-(6-O-trans sinapoyl glucopyranosyl) gardendiol, isoquercitrin, scortechinones, secaubryenol, iridoids and quercetin 3-rutinoside (rutin). The extract showed antioxidant activity (IC50 = 65.82) and powerful antibacterial activity with lowest minimum inhibitory concentration against Gram-positive Staphylococcus aureus (15.62 µg/µL), Bacillus subtilis (31.25 µg/µL) than gram negative Escherichia coli (62.5 µg/µL), Klebsiella pneumoniae (62.5 µg/µL), Pseudomonas aeruginosa (31.25 µg/µL). This study shows that the fruits of G. latifolia have tremendous potential to be used in food industries, phyto-therapeutics and cosmetic industries.

Caffeoyl Quinic Acid

A new high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS) method has been developed for the simultaneous determination of nine major compounds, namely chlorogenic acid (1), caffeic acid (2), sweroside (3), loganin (4), secoxyloganin (5), 3,5-di- O-caffeoyl quinic acid (6), luteolin-7- O-glucoside (7), rutin (8) and 3,4-di- O-caffeoyl quinic acid (9), in Caulis Lonicerae Japonicae (CLJ), a commonly used traditional Chinese medicinal herb. The separation was achieved on a C-18 column (250 × 4.6 mm, 5.0 μm) with a column temperature of 30°C and a flow-rate of 0.8 mL/min. The mobile phase was composed of (A) aqueous formic acid (0.1%, v/v) and (B) methanol, using a gradient elution of 30% B for 0-13 min, 30–40% B for 13–17 min, and 40–49% B for 17–30 min. The limit of detection ( S/ N = 3) ranged from 0.8 to 5.1 ng/mL and the limit of quantification ( S/ N = 10) varied from 3.4 to 16.9 ng/mL. All calibration curves showed good linear regression ( r2 > 0.9976) within the test ranges. The intra- and inter-day precisions, as determined from sample solutions, were below 2.2 and 4.3%, respectively. The recoveries for nine compounds were within 91.3 and 104.2%. This proposed method has been successfully applied to evaluation of commercial samples of CLJ from different markets in China, which provides a new basis of assessment of the quality of the herbal drug.
