Two phenylpropanoids, three caffeoylquinic acid deravatives and an iridoid were isolated from the stem of Lonicera macckii. On the basis of physico-chemical data, these compounds were identified as caffeic acid methyl ester(1), 5-caffeoylquinic acid n-butyl ester(2), methyl 3,4-dicaffeoyl quinate(3), 3,5-dicaffeoyl quinic acid n-butyl ester(4), loganin (5) and caffeic acid(6). All compounds were isolated for the first time from the stem of this plant.

From $70\%$ ethanol extract of the roots of Smilax bockii warb., seven flavonoids, kaempferol (1), $kaempferol-7-O-\beta-D-glucopyranoside$ (2), quercetin (3), isorhamnetin (4), (+)-dihydro­kaempferol (5), engeletin (6), isoengeletin (7), and $n-butyl-\beta-D-fructopyranoside$ (8), caffeic acid n-butyl ester (9) were isolated and identified by means of chemical and spectroscopic. Compounds 2, 4, and 6-9 were isolated for the first time from the roots of S. bockii and compounds 2, 8, and 9 were firstly isolated from the genus Smilax. In addition, using the SEAP (Secreted alkaline phosphatase) assay system, we investigated the in vitro anti-inflammatory activity of the $70\%$ ethanol extract of the roots of S. bockii, which showed moderate activity in inhibiting $TNF-\alpha-induced NF-{\kappa}B$ activation with an $IC_{50}$ value of $166.6 {\mu}g/mL$.
