“…The sequence of sample 3 was consistent with the sample being a hybrid of L. vellerea and L. kanaitzensis (sample 6). From the atpB-rbcL sequence of sample 3, its maternal parent was judged to be L. vellerea, as the sequences were distinct between L. vellerea (sample 1, see also [4]) and L. kanaitzensis (sample 6, see also [7,8]). The parental lineage of sample 2 could not be deduced, as the atpB-rbcL sequence was similar to that in L. cyathiceps [9] and L. vellerea [4] (Table 2).…”

Ligularia vellerea and L. melanothyrsa have been found to share chemical characteristics based on geography. In one chemotype (Shangrila type), the major components were either 15-oxygenated furanoeremophilanes or eremophilanolides; and in another (Luguhu type), either 1-angeloyloxyfuranoeremophilanes or corresponding lactones. The two L. vellerea samples were found to have experienced hybridization with either L. cyathiceps or L. kanaitzensis; however, compounds typical of L. vellerea alone were isolated from them.

“…The 2 methyl groups of the senecioate (= 3-methylbut-2-enoate) moiety in 6-senecioyloxy-1,10-epoxyfuranoeremophilane was observed at δ 2.13 ( Z -Me) and 1.43 ( E -Me) in C 6 D 6 . 17 HMBC correlation was observed between H-6 and C-1″ for both 1c and 1d , supporting that 1a , 1c , and 1d are variants of the acyloxy group at C-6.…”

The composition of root chemicals was studied for 7 samples of Ligularia tongolensis collected in Yunnan and Sichuan Provinces of China. The structures of 2 new 3β-angeloyloxy-6β-acyloxyfuranoeremophilan-15-oic acids were determined. It was found that the plant harbors chemical diversity in the acyloxy groups in 3,6-bis(acyloxy)eremophilan-15-oic acids. The presence of a 3-methylpentanoate moiety at C-3 appears geographically differentiated to a degree. Consistent with this low diversity, results of DNA analysis indicated little genetic differentiation, although introgression was inferred for one of the samples.

“…In the hope of obtaining a clearer picture of the phylogenetic structure of L. kanaitzensis , we carried out analysis on the present and the previous samples, [9,10,27] totaling 27, listed in Table S3 . For this purpose, we re‐analyzed the samples whose sequences remained ambiguous using a new set of primers [9,10,28] . The ITS1‐5.8S‐ITS2 sequences are summarized in Tables S4 .…”

Root chemicals and the sequences of the internal transcribed spacers (ITSs) were analyzed for 9 Ligularia kanaitzensis and 3 L. subspicata samples collected in northwestern Yunnan and southwestern Sichuan, China. Subspicatins A and C were isolated from two L. kanaitzensis samples. Introgression of genes responsible for these compounds from L. subspicata was suggested by their strong connection with L. subspicata/L. lamarum and the geographical proximity of the samples to L. subspicata. DNA analysis of a set of 27 L. kanaitzensis samples including those analyzed previously showed that they belong to two clades, designated A and B. Together with the presence/absence of furanoeremophilane, the 27 samples were sorted into three groups: clade A/furan, clade B/furan, and clade B/non‐furan. The ancestral plant presumably belonged to clade B/non‐furan, because furanoeremophilanes are biosynthesized from eremophilan‐8‐ones. 1β‐Angeloyloxyfukinone, a likely intermediate between fukinone and subspicatin C, was isolated for the first time. This finding allowed us to propose plausible biosynthetic pathways of subspicatins A and C.
