Phytochemical investigations on the leaves of Valeriana officinalis L. led to the isolation of 18 compounds, including eight lignans (1–8), three sesquiterpenoids (9–11), five iridoids (12–16), and two aldehydes (17–18) The structure elucidation of isolated compounds was achieved on the basis of NMR and mass spectral data. Among them, three compounds (9–16 , 18) are reported from V. officinalis for the first time and one compound (5) was isolated from the genus Valeriana for the first time. In addition, six compounds (2 , 4 , 6–8 , 17) are isolated for the first time from Valerianaceae family. The chemotaxonomic significance of these isolated compounds has also been discussed. Image 1 • Compounds 9-16 and 18 were firstly isolated from Valeriana officinalis L. • Compound 5 was identified for the first time from the genus Valeriana. • Compounds 2 , 4 , 6-8 and 17 were new for the family of Valerianaceae. • The chemophenetic significance of the isolated compounds was discussed.

A new C21 steroidal compound (1), along with 12 known compounds (2 – 13) were isolated from the whole herb of Pachysandra terminalis Sieb. et Zucc. Their structures were determined by extensive analysis using various spectroscopic techniques. Notably, compound 6 was reported for the first time from P. terminalis , and compounds 3 – 5 , 7 and 9 were isolated from the family Buxaceae for the first time. Image 1 • Thirteen compounds were isolated from the whole herb of Pachysandra terminalis, one of which was a new compound. • 6 was reported for the first time from P. terminalis, and 3-5, 7 and 9 were identified for the first time in Buxaceae. • Our findings have showed the chemotaxonomic significance of P. terminalis.

Chemical investigation of the root and rhizome of Silene tatarinowii Regel led to the isolation of nine ecdysteroids (1–9) and one sterol (10). All the compounds were determined on the basis of MS and NMR and by comparison with those in the literature. All these compounds were isolated from S. tatarinowii for the first time. Furthermore, compounds 7 – 10 were isolated from Silene genus for the first time, of which compounds 7 and 8 were isolated from Caryophyllaceae family members for the first time. This is the first study to report the chemical constituents of S. tatarinowii and the chemotaxonomic relationships between Silene and other genera of Caryophyllaceae. Image 1 ● Ten compounds were isolated for the first time from the roots and rhizomes of Silene tatarinowii. ● The compounds were assigned as ecdysteroids and sterol. ● First study to report these compounds in S. tatarinowii. ● Compounds 7–10 were identified for the first time from the genus Silene , and compounds 7 , 8 were new for the family of Caryophyllaceae.

Phytochemical investigation of the roots and rhizomes of Smilacina japonica A. Gray led to the isolation of 16 compounds, including six steroidal saponins (1-6), one amide (7), one fatty alcohol (8), one steroidal sapogenin (9), two flavones (10 - 11), one glycoside (12), one phenol (13), one aliphatic acid (14), and two sterols (15-16). All of these compounds were isolated for the first time from the roots and rhizomes of S. japonica while compounds 1 - 13 were identified for the first time from the genus Smilacina , of which compounds 9 , 11 , and 13 were isolated from the Liliaceae family for the first time. Furthermore, the isolation of compound 9 was reported for the first time in plants. Their structures were identified by spectroscopic methods and compared previously published data. The chemotaxonomic significance of these isolated compounds has also been discussed. Image 1 • Sixteen compounds were isolated for the first time from S. japonica. • The compounds were assigned as steroidal saponins and sapogenins, flavones and other constituents. • Compounds 1 - 13 were identified for the first time from the genus Smilacina , and compounds 9 , 11 , 13 were new for the family of Liliaceae. • Compound 9 was reported for the first time in plants.
