“…However, because there is no previous report that allyl esters occur naturally, the possibility of an uncontrolled source of contamination cannot be eliminated. Diethylphthalate also has not been unequivocally shown to be a naturally occurring constituent, but it has recently been reported that diethylphthalate was found in diethyl ether extracts of wheat leaves (14), and an increase 'Compound designations in parentheses denote tentative identification. of diethyl phthalate was observed to occur during fermentation of honeysuckle berry wine, Lonicera edulis (15).…”

The Salvia mellifera (Labiatae) assemblage consists of S. mellifera Greene, Salvia munzii Epl., Salvia brandegei Epl., and Salvia columbariae Benth. These four species comprise a clearly defined natural group and are easily separated from the other California Salvia species by distinctive morphological characters. Three of these species formed subsection Parishiella when Epling elevated two varieties within S. mellifera (i.e., var. brandegei and var. munzii) to specific level (1). The inclusion of the fourth member, S. columbariae, to the natural grouping was first suggested by Neisess (2). The most definitive characteristic of this group is the flower type, which is uniquely suited to optimize pollination by smalland medium-size bees (3). S. mellifera is a dominant species in much of the California coastal scrub sage and bordering chaparral zones from Contra Costa County south to the border of Baja California. In northernmost Baja California as the coastal sage scrub becomes increasingly xeric, S. mellifera is replaced by S. munzii, which ranges as far south

It is widely believed that phthalates are xenobiotic pollutants whose prevalence in the environment is associated with their facilitated diffusion from plastic materials. Studies into the effect of synthetic phthalates on living organisms revealed their extremely negative action on the metabolism of animals and humans. The acting mechanism of these compounds is realised through a ligand-receptor pathway. Along with dioxins, polychlorinated biphenyls and similar compounds, phthalates are classified as endocrine disrupters. However, at present, sufficient evidence has been accumulated confirming the natural origin of phthalates. Thus, phthalates were de novo biosynthesised from labelled precursors in an algae culture. These compounds were detected in closed experimental systems, including cell cultures of highest plants, as well as those isolated from a number of bacterial, fungi, lowest and highest plant forms located far from the sources of technogenic pollution. The concept of phthalate biogenesis assumes the action of these compounds on living systems. Phthalates exhibit bactericidal and fungicidal action and compose allelopathic exudates, suppressing the growth of competing plant forms. Phthalates possess insecticidal and repellent properties. An analogy can be traced between the action of phthalates and endocrine disrupters of another chemical category, namely phytoestrogens, which regulate herbivorous mammal populations. A hypothesis is proposed about the biological role of endogenous plant phthalates representing secondary metabolic compounds. Exhibiting predominantly a shielding function, these compounds participate in the network of interactions between plants, animals, fungi and microorganisms. It should be noted that synthetic and endogenous phthalates are characterised by essential stereochemical differences, which can explain their different action on living organisms.

Mimusops elengi, commonly called Bakul, is a medicinal plant belonging to the family Sapotaceae. It is a small to large evergreen tree up to 15 m in height. All parts of the tree have medicinal properties. The bark, flowers, and fruits are acrid, astringent, cooling, and anthelmintic [1]. The bark is used as a tonic [1][2][3][4], febrifuge, and as a gargle for odontopathy, inflammation, and bleeding of gums [1]. The powder of dried flower is a brain tonic and is useful as snuff to relieve cephalalgia. Young twigs are used for cleaning teeth [2]. It is antipyretic and increases fertility in women [1,3]. It is also useful in urethrorrhea, cystorrhea, diarrhea, and dysentery. Flowers are used for preparing lotion for wounds and ulcers [3]. The unripe fruit is used as a masticatory and helps to fix loose teeth. Seeds are used for preparing suppositories to treat constipation, especially in children [2][3][4]. Ripe fruit pulp is useful in chronic dysentery [3,4]. Leaves are used in snake bite [3,4].In our continuing research on bioactive metabolites of plant origin, we have isolated dibutyl phthalate (1) for the first time from the bark of Mimusops elengi. It has been also isolated from other plants, marine algae, bacteria, and fungi [5][6][7][8]. The cambridge Crystallographic Database has been searched for single-crystal analysis. So far, the molecular structure for compound 1 has not been determined; however, the manganese complex of the same has been studied by D. Moon and M. SooLah [9]. General Comments. Instrument: HPLC (Shimadzu 2010, LC Solution); LC-MS (Shimadzu 2010, LC-MS). Solution. Instrumental conditions: HPLC column YMC ODC -A (5 cm u 4.5 cm u 5P), A = 0.1% TFA in H 2 O, B = 0.1% TFA in acetonitrile, gradient = 5% B to 90% B in 8 min hold for 2 min, injection volume 3 PL; column oven temperature 30qC; flow rate = 1.0 mL/min. LC-MS conditions: scan mode = positive; CDC temperature 250qC; heater block 200qC, detector voltage 1.5 kV; scan speed 1000 amu/sec; nebulizing gas flow 1.5 L/min; ionization mode ESI (atmospheric pressure ionization).Extraction and Isolation. Plant material used in this study was purchased from the market. It was authenticated at the Agharkar Research Institute, Pune, India. Its authentication number is AHMA S/B-065. Air shade dried powdered bark material (300 g) was extracted with a Soxhlet extractor using different solvents such as hexane, chloroform, ethanol, and methanol for 18 hours. The solvents were removed under reduced pressure to get the respective extracts. The chloroform extract (1.33%, 4.018 g) was further purified. Broad fractionation of the crude chloroform extract (4.0 g) was carried out using gradient polarity solvents on silica gel (60-120 mesh, 160 g) to get ten fractions. Fractions were monitored by thin layer chromatography. Fractions 3 and 4 (toluene, 100%, toluene-ethyl acetate, 75:25, 1, 2 g) were mixed together for repeated column chromatography using gradient polarity solvents on silica gel (60-120 mesh, 60 g), and a total of nine fractions was collected. ...
